About GunWorks

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 Harrington, 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

Jim,

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.

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.

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.

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.

Jim,

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

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!

Jim,
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.

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

Jim,
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.

Jim,

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?

thx

Roger

Jim,
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.

Thanks
Bob

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.

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.

Jim,
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,
Jason

Reply

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

Sir,
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 ?

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!!!!

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?

Thanks

Christopher
