About GunWorks

Gunsmith Jim Green standing beside the GunWorks sign.

Gunworks offers firearms repair and custom-made ammuntition for modern and obsolete cartridges. Services include but are not limited to custom built guns (bolt action hunting and target rifles, semi auto military style sporting rifles, and handguns), rust blue, hot salt blue, Dura Coat, and Gun Kote firearms finishes, rebarreling, caliber conversions, and drill and tap for receiver sights or scope bases.

The shop is located on Route 1 in Milbridge Maine, and is open from Tuesday – Saturday from 9:00 AM – 5:30 PM. GunWorks is closed on Sundays and Mondays. Please see the Shipping Information page for address and shipping info.

The shop can be reached  via email at m u l e e q u e s t r i a n [at] y a h o o . c o m.   As I am a small shop and sole proprietor, I had to change the number for the shop and no longer list it to the general public. When the phone would ring and I had to spend an hour at a time talking to people about non gun related items I wasn’t able to get my own work done. It’s unfair to the customers who are waiting for their repairs to be completed. IF YOU SEND a firearm in for repairs, you will be given the new phone number at that time. GunWorks is owned and operated by Jim Green. Jim is a former U.S. Marine and a veteran of the Gulf War. His primary job was as a field artilleryman, but he also spent 4 years as a small arms instructor at Camp Lejeune.

Mr. Green,

After several years of — for the most — ignoring YouTube, last year I finally discovered a real USE for the website; the disassembly and reassembly of various firearms. I own a Remington 11-87, and — after I had first bought it — I had the gun mostly apart, had locked the bolt back, then inadvertently pulled the trigger. After that, I’m sure you know, the bolt would not operate correctly.

I took it to my local gun shop, Loudon County Sportsman, and one of the owners diagnosed the problem and fixed it. Several years later, my 17-year-old son was — instructions in hand — taking the shotgun down and reassembling it. I blame my self for the fact that he did the same thing I did, because I was in the room, and failed to warn him.

About a week after, I thought that I might find something to help on YouTube; I did. It was a detailed, and well-narrated piece on the complete disassembly and reassembly of a Model 1100, which is close enough in design to suffice. You probably already know that the bolt spring had come out of its retaining slot, but I learned enough from this video to get everything ship-shape very quickly.

I have now acquired a Model 7400 in .308, and after watching your video presentation, I am confident that, after I finally take it to test-fire, I will be able to disassemble, clean, and reassemble the rifle with only a small learning curve.

Thank you for the videos, your service in the Corps, and a lifetime of being part of the solution, as opposed to being part of the problem. By the way, from which part of the American south do you hail, and how did you wind up in New England? Clearly, you are not a local. I know that because I am a lifetime East Tennesseean and Vol fan.

Most Sincerely,
Wesley R. Loftis


Peter Raples May 10, 2011 at 10:53 PM

Jim, saw your breakdwn of a 1907 winchester got a major question any tips on getting the bolt spring and the bolt and rod back together, I spent a couple hours and could not get it back together any hints?

Thank You


Maged Nashed May 22, 2011 at 12:23 PM

Jim: I saw your video on the model 8 and would like to THANK YOU for such a
very well made informative video.
I have a model 8 in a 30 Rem that i would like to restore, the inside of the gun
is in very good to excellent condition including the barrel condition.
What i would like to have done ,is a complete take apart clean and reblue.
The wood is perfect and would like to keep it as such.
Can this be done and at what cost and time, what kind of reblue do you
NB: live in California
Thank you.


Jim Green, Gunsmith May 22, 2011 at 6:53 PM

Angus Johnston June 11, 2011 at 3:59 PM


Can you please help me out? I have a Remington 7600 model pump action rifle. I would like to see a video of the complete disassembly when you get a chance (if you could post it on “youtube”) Maybe there are other Remington models that break down the same exact way. The problem is getting the barrel off. All I want to do is to give it a good cleaning. Thank you in advance for your time and assistance.

Angus Johnston


Jim Green, Gunsmith June 11, 2011 at 9:39 PM

NOT a problem…. to get the barrel off is easy enough. Once you remove the handguard from the pump tube ( hey you know how to do that right ? ) you’ll notice you have a tube on which the slide moves. OK… you’ll see a couple of holes in this tube. Stick a heavy duty pin punch in there and UNSCREW the tube just like it was a reallly long barrel nut.

The rest of the gun disaaembles very similar to the 7400 as far as the bolt assembly goes.


Henry Varrone August 7, 2011 at 11:53 PM

I just purchased Uberti 1873short rifle. Uberti does not show how to clean inside of receiver. Can I just remove left side plate without any parts falling out to clean inside. Also ,do you do action jobs on this gun. The trigger is very heavy.


Chuck Linderman August 29, 2011 at 4:40 PM

Dear Jim,
Thanks for the EXCELLENT video on The Remington Model 11. I’m working on restoring one right now and your video was a godsend. You may wind up with this old girl on your bench as I’m having issues with her.
Thanks a million for your Service. I too was a Field Artillery Crewmember (11B) served on a towed155mm Howitzer. Keep up the good work and keep those videos coming.


Wayne Rouse September 10, 2011 at 1:21 PM


Thanks for the great video. I have a model 11 remington 12 guage. I was having trouble with it cycling, so I was able to disassemble the gun…with the exception of the trigger, and reposition the friction ring. It will kick shells now, but will only fire one shell. After it kicks the shell, it feels like the safety is on. Do you have any suggestions as to what may be the cause of this. Thanks in advance


Craig C. Smith October 15, 2011 at 9:37 PM

Thank you so very much for the video of the Remington model number 8. It taught me enough that i need a new firing pin. i sent an email to your web sight and look forward for an answer.Best Regards:
Craig C. Smith


Eric Sens December 1, 2011 at 7:47 PM

Dir Sir,

I really appreciated your YT vid on how to make ammunition. I have learned a lot and under the strict Dutch laws on guns and ammunition I have made my first batch of 9 mm ammunition. Self casted the bullets, reloaded them and had great results with them!




Mark Johnson December 3, 2011 at 10:20 PM

Outstanding video on the 7400. Have had mine since 81 and recently got it soaked while hunting in Tennessee. Got back to Texas and needed to tear it down. Your video was exactly what i needed as i’ve never completely stripped it since purchasing it. It’s cleaned up and ready for quite a few more years of knocking em down. Thanks again.



Chase wheeler December 17, 2011 at 5:37 AM


I was just curious to how you got started doing gunsmith work and how you learned it all? I live in Texas and I like working on my guns and would like to get into it as a profession but I’m not sure exactly how? Any help on these would be great


Dennis Chagnon December 27, 2011 at 6:47 PM

Thanks for your video on the model 94. As you know the economy sucks and a friend of mine hit some tough times. I loaned him a couple of hundred bucks and he gave me his fathers gun for colateral. I figured I would clean it while I had it under my care. I don’t believe the thing has been thoroughly cleaned since it was new in 46, the oil in the bolt area is like really thick grease. Any suggestions on a good solvent to cut the sludge would be appreciated.


Roger Budris February 1, 2012 at 2:45 AM


Recently acquired a 1907 Savage 32 made in 1919. It has a 1907 frame and hammer but a 1917 slide. It is a real bear to rack the action. I can hardly do it and feel something is wrong as original advertisements for the gun seemed to be for women. Aren’t too many women going to rack this gun. If I cock the hammer first then racking it is almost reasonable. Cocking the hammer is really hard to do too. After watching your video I field stripped it and sure enough the tigger safety slipped out of the tigger assembly notch. Getting that back together seemed near impossible because the trigger safey is spring loaded and sticks out from the slot. I had to use a small screw driver to push it back into the slot while sliding the trigger assembly in. Whew.

I could see nothing obviously wrong while I had it apart.

The gun came to me well lubed and seems to be in very good shape. Blueing is very good, grips are good, no dings or scratches so it seems to be well cared for. Any suggestions on what to try first?




Linda Desjarlais February 4, 2012 at 1:27 PM

I have a high standard duramatic 22lr that I want to give to my grandson. The pistal was my fathers. I have had it cleaned and checked out. It’s in good condition. Could you give me some history on the gun. I would appreciate your input. Thanks


Bob Meyer April 4, 2012 at 6:38 PM

I am really impressed with your site and signed up for your ‘Tips’ videos. Last week I picked up a Remington, 20ga., Mod 11A, Sportsman. When shooting it, it went full auto for two rounds and fired the last round correctly. Is a good cleaning all that is necessary or should I have you or a local gunsmith take a look at it. I am in Indianapolis, Indiana.



Jim Green, Gunsmith April 14, 2012 at 4:44 PM

Try a good cleaning first. See if you notice anything out of place, or any burrs / broken parts. But you may have to send it to a gunsmith.


graham holmes April 19, 2012 at 12:01 PM

Dear Mr Green
i would like to thank you for posting the video of the disassembly of the franchi 48 AL on Utube i really enjoyed the video, i would like to ask a question on the gun if you dont mind, i found that it wont eject light loads, i was out yesterday clay piegon shooting, i was using a 24 gram 1oz 7 and a halfs compacts but it wouldnt eject them, is there a way of changing is so it will use light loads, thanks graham holmes in hartlepool, uk


Jeffrey Nault May 4, 2012 at 9:21 PM

Mr Green,

I have been following you for some time now (very interested in the new ammunition material stuff you’re doing). I believe that I remember from sometime ago that you said that you do more than just blueing.

Do you do other types of finishing? If so, I just inherited an 870 express and was told it was rusty. I want to convert it to a tactical platform. What would you suggest, Duracoat maybe?


Jim Green, Gunsmith May 6, 2012 at 10:25 PM

Flat black Dura Coat is a decent start.


Steve Dickman May 20, 2012 at 2:03 AM

I am interested in finding out how much you would charge for one of your Steel Guide Rod for the GSG 1911 (.22Lr). I just purchased one at the Gun show in Portland, Oregon.
After watching your YouTube video I was very impressed with your gun smith talent.

Jason May 31, 2012 at 9:21 PM

i saw your video on the browning fn 1922 handgun. i was wondering if i sent u pictures if you could date the one i have? im very curious as to the year and history of the gun


Jim Green, Gunsmith June 12, 2012 at 9:55 PM

I can try. Send the pics.


Jason July 7, 2012 at 5:32 AM

Love your vids, very helpful when i need to clean that odd gun that Iv only seen in books . I am by NO means a gunsmith but i’v collected modified and upgraded firearms for 33 years now. All for friends and family without compinsation.
I can usually find any parts i need or machine something that will do , being that i have worked as a machinist since “97″.
However finding a fireing pin for late 60′s Mossberg 800ASM .308 bolt action seems imposible.
I tried to make one , but the tapper is more than 2.875″ and has proven probelmatic.
Are you familiar with this model?
What can you suggest?

Up and down range,


Jim Green, Gunsmith July 7, 2012 at 10:07 AM

If the firing pin is broken at the tip, what I usually do is center drill the end that’s broken off. I put a new piece of metal such as drill rod in and silver solder it in place. Then shape the tip into a slightly flattened hemisphere shape. If you’re having a hard time locating a new firing pin, haveyou tried Jack First in S. Dakota, or even Numrich in New York yet ?


Rudolf Burgherr August 7, 2012 at 6:05 AM

Dear Mr. Green,

on YouTube, I found an excellent video, in which you dismantle a Winchester 1894. Is there also a similar video with a Winchester 1892? I would be interested very much therefore!
Thank you for an answer!

Yours truly
Rudolf Burgherr, Switzerland


Ken Warren September 4, 2012 at 10:04 PM

Semper Fi Jim and thanks for your service. I really appreciate your video on the Ruger .44 carbine. I’ll be cleaning one this weekend.

Paul September 22, 2012 at 11:08 AM


I loved your disassemble of the Savage 99…what a wonderful firearm. Also thanks for serving our great country. I was wondering if you have any recommendations for a steel weaver style two piece mount for the Savage 99. I’m currently using Weaver Aluminum mounts, but I’ve always felt more stable with steel.

Let me know and great videos!!!!




Robert Horton December 19, 2012 at 7:32 PM

Seen your vido on the Winchester 94 scout scoping. I just bought one and using the serial number i dated it around 1991. Do i have to scout scope it or can i just scope it the regular way

yours truly
Robert Horton

Jim Green, Gunsmith December 25, 2012 at 2:14 PM

Your rifle is an Angle Eject model. You can scope it in a normal way, on top of the receiver.


ahmed hussein December 24, 2012 at 5:18 PM

Hi Jim I was wondering about the bruni mod 92 it’s a blank shooting pistol can I change the barrel to true bullet shooting barrel , if I could can you send me video to show me how to do it .thank you Jim


Jim Green, Gunsmith December 25, 2012 at 2:13 PM

no, the gun is not designed to handle this kind of pressure. Not only is it illegal, but dangerous too.


christopher Lee January 3, 2013 at 2:00 AM

Mr Green,

I’m thinking of having you make me an ak style sporting rifle in the near future from parts but have a few questions since I’m a relative new that gun system.

First I’m a big fan of the .223/5.56×45 round and saw in your video that you build that caliber. My question is do you think the .223 in your experience is a reliable round in the AK style system or would the more traditional 7.62×39 or 5.54×39 ammo are the only ones that are reliable in the AK variant?

Second questions is if you can make a reliable .223 ak which you think are quality magazines for the .223 variant that aren’t impossible to find and lastly which variant parts kit is the best one for building a .223 variant ak sporting rifle or if there is little difference between them?

Lastly, which 7.62×39 parts kit variant do you think is best to build on as if there isn’t a reliable .223 option that is my fall back plan?




Jim Green, Gunsmith January 26, 2013 at 8:08 PM

Sir, the .223 or 5.56 cartridge in the AK fires fine. I have one myself. Check with Apex in CO for parts kits availability.


Ken Savoy January 6, 2013 at 11:37 AM

Mr. Green
I have watched many of your videos and have found them to be most helpful. I have a need for a good gunsmiths bench block how ever I can’t find one like yours that you use on your videos. Can you tell me where you got it and brand name as well? I have a home made version not nearly as practical as yours. What ever information you can give me will be appreciated. Thank you for your service to our country I too am a veteran I spent nearly 10 yrs. in the US Navy.

Hi from Italy Mr. Green!
I have to thanks you very much about your video “Gun Works – M1 Garand (.30-06)”.

I had needed some informations about assembly this rifle and your video was very useful to me. You have a new surplus enthusiast friend from Lombardy – Italy.

All the best!

Steve Crawford February 20, 2013 at 7:17 PM

Ref: Remington 1100 Youtube video.
Thanks Jim as my gas piston was also stuck in the cup and this video helped me troubleshoot my ejection problem. I bought my shotgun used, she was extremely dirty, and I didn’t have the users manual to show me how to tear down and reassemble, which I can now do in a matter of minutes.


Rick Sanders March 16, 2013 at 10:45 AM

Dear Mr Green, first of all thank you for your service. I recently bought a Uberti 1873 45LC. I then proceed to overload the magazine. It fed two and jammed the ejector. Your video on tear down to clean was my salvation. Once again the Marines save the Navy. Wishing you fair winds and following seas.
