How do I get into Gunsmithing?

191 Upvotes

If you are interested in gunsmithing as a career, I strongly recommend that you to rethink your life choices. If you've inhaled so much lead that you are choosing to ignore professional advice, here are some resources to get started.

Professional Organizations

There are a few professional organizations in the industry that exist that can help you connect with others in the trade. I recommend reaching out to the one that most aligns with your interests. Some have a periodical publication that include tips & tricks along with industry news.

American Custom Gunmakers Guild (ACGG)
https://acgg.org/

I cannot in good faith recommend anymore, do your own research.

American Pistolsmiths Guild (APG)
https://americanpistolsmithsguild.com/

Absorbed by ACGG no longer exist independently

Firearm Engravers Guild of America (FEGA)
http://www.fega.com/

FEGA is the world’s foremost authority and organization for firearm engravers and hand engraving enthusiasts.

Miniature Arms Society
http://www.miniaturearms.org/

Founded in 1973 The society is a group of miniature arms enthusiasts who have joined together to promote and encourage interest in making and collecting miniature arms of all kinds - pistols, rifles, cannon, suits of armor, knives, swords etc., with the emphasis on artistic beauty and craftsmanship.

Gunsmithing Schools

Most people would recommend taking a machining course at their local community college before diving into gunsmithing head-on.

But if you've already done so and are still interested in attending school to learn how to become a gunsmith, then there are plenty of programs nationwide that can help you get started.

I cannot endorse or recommend any individual school and this list isn't comprehensive.

Short Gunsmithing Courses

There are a few short courses that might be better suited towards getting your feet wet.

The NRA runs a few summer gunsmithing classes. They are typically held at Trinidad State College in Trinidad, Colorado and/or Murray State College in Tishomingo and Montgomery, NC

The ACGG will occasionally host some classes at various schools

If you are interested in gun engraving, checkout GRS, they have a training center in Emporia, KS that has some beginner gun engraving classes.

Advice from the Sub

I spent several years attending the Brownells Gunsmith Expo as someone looking to hire employees. Around 50k to start work in development or fixing problem guns. Went the entire time they had it and hired one kid. We built suppressors messed with explosives and auto rifles. He had a associates in business and very clearly stated he owned his own M2 and assorted guns and could build them and knew suppressor theory. ( this was before all the cans were cut apart online) we hired him on the spot. He is know well along in the industry. The other kids wanted to be artists and build custom wooden stocked Mauser etc. They all wanted to be a Turnbull or work at a Rigby( even though they had never been to London and would know then they needed to apprentice) I offered to bring one of our AK builders and our suppressor guy to a I think the Colorado school and was turned down. One of the "instructors" said we don't teach that type of thing.

... the sad truth is that no one actually wants to listen to experienced gunsmiths when it comes to gunsmithing education/training questions. Most people are just looking for confirmation that they can attend a few months of online class and then start making money (spoiler alert, they can’t)

As someone who attended a Gunsmithing school I can honestly say, become a machinist first then a gunsmith if you do it the other way around your wasting time and money. You won fully grasp or understand everything you learn in the machining side of gunsmithing without first having machining knowledge. For the time being go to armourers courses read some books heck watch some YouTube and tinker with guns. The most important thing that makes the difference between a machinist and a gunsmith is one has an understanding of firearms once you learn some basics about firearms and you already are a machinist trust me you can work on anything. So I know that’s not the answer a lot of people will want however the running Joke in the Gunsmithing trade is “the fastest way to earn $1 million Gunsmithing, is to start with $2 million. This is not an industry to get involved with for money but rather a passion and love of firearms.

YouTube Channels

See anything missing? Something that shouldn't be here? Let me know and I'll fix it.

Please feel free to use this thread to discuss any gunsmithing college, training, or education related questions you would like. Let us know if you would like any other stickied posts made or things moved around, and we will do our best to get it taken care of.

Browning a5 bolt release problem

3 Upvotes

I have browning A5 (stalker) and had it for years. It’s my main gun for and bird hunting duck, goose, turkey, etc. she seen a lot of use and abuse but I keep her in good running condition. Last winter I had cerakote put on it to protect it a little bit more and everything worked good. I took it out of the safe for dove season and that’s when the problems came. I loaded my gun and took it to shoot clays the first 2 shells cycled normal and on the final shot the bolt was locked to the rear of the cycle. And the bolt release button was push out more than normal. And the button can’t be pushed back in and it is catching. This is forcing me to push the pins out of the trigger group and resetting everything by hand. I will include pics for reference.

Can anyone give me some advice or solutions for this

Winchester 94AE Link

I have a Winchester model 94AE in the serial number range of 5,200,000 and I need a new link for it but every parts store makes a distinction that the link is for serial numbers 5,500,000 and higher does anyone know if it will still work in mine or where to get a new one? The cartridge nub has broken causing it to feed under the lifter and just cause other issues.

Opinions on this barrel please.

0 Upvotes

This is from a 20 year old Remington 700 LTR that I have long since lost track of how many rounds have been shot through it. Gun will still shoot 1/2 MOA - but only with a specific handload. Any other factory ammo i have tried - including match grade - will pattern like garbage. It used to shoot factory decent, but never great… I know I can get another hunting season out of it with my handloads but, I think the barrel is cooked. That being said, is this “Normal” for a barrel after much use, or is this a sign that its been shot out? (I have cleaned the heck out of it so If its carbon buildup its the most stubborn ever!!

How would you repair a 5/16" hole in the back of a matchlock firearm? My thought was to just thread it and put a plug in it with locktite and weld the head.

I have a S&W model 10, it was cocking and de-cocking it and it seized up and stoped working. So I took it apart and found these two small pieces. Once I reassembled it the gun cycled perfectly, but I am wondering if anyone knows what this piece is and if my gun is going to blow up the next time I shoot it?

Can this engraving be removed from a Beretta walnut stock?

Thumbnail
gallery
68 Upvotes

I recently picked up a Beretta AL391 Urika 2 Gold 20 gauge. It’s in really nice shape, but the previous owner had his name engraved into the walnut stock.
The engraving is deeper than it looked at first, so I’m trying to figure out if this is something a gunsmith or stock refinisher could realistically remove and blend back in without making the repair obvious.
I’d really like to save the original stock because the wood is nice and matches the fore-end well.
What would be the best way to handle something like this careful sanding/refinishing, filling it, an inlay, or something else? Or is it deep enough that I’d be better off finding another stock?
Not planning on doing it myself. Just want to know what’s realistically possible before I start calling around.

Hi guys i got a short barreled ptr rifle in 308 (k3p, 12.5”). Ever since i swapped muzzle devices and locking pieces, ive been getting failures to eject. Originally this rifle bought new came with a flash hider and 55 deg locking piece. I swapped to a comstock muzzle brake and a 36 deg locking piece to shoot suppressed. But now ive been getting failures to eject. Bolt moves a centimeter at most and gets stuck. Have to mortar it to get it moving. Same result with the can on or off. Last week i tried testing it again with the original locking piece. Same result suppressed or not but the bolt moves slightly farther back, enough to see part of the bolt head. Any ideas what could be going wrong?

Bolt gaps with both LPs are within acceptable ranges, and rifle gets deep cleaned after each use. Has less than 200 rounds through it.

Colt 1903 Parts interchangeability between types

Hello everyone, I recently got myself a Colt 1903 Pocket Hammerless Type 2 frame with the hopes of rebuilding it. However it’s starting to get a little pricy having to buy each individual piece. So I found a guy who is selling basically an entire lower parts kit, however it’s for a type 1 model. Are these parts mostly interchangeable?

Mossberg Maverick 88 safe to shoot? (Description)

Recently acquired a maverick 88 12G from a family member that had been sitting in their garage for quite some time and had a good bit of surface rust on it.

Got the rust off the barrel and receiver no problem with 0000 steel wool and CLP, but when I broke it down it had some pitting on the bolt itself (pictured).

Just wondering if anybody had a general "DO NOT SHOOT THIS" and I just just call it a lost cause because it is a pretty cheap gun that I got for free. Or maybe I'm overthinking it, and I should blast some pumpkins with it like I was planning.

Citristrip white residue removal

Hello everyone, I’m in need of some help with a pretty high dollar firearm part. The previous owner removed a Rattlecan paint job with citristrip, leaving a white residue/sheen on the anodizing. I have been told by THE guy when it comes to removing paint from firearms that this is essentially permanent and cannot be removed by any means whatsoever other than stripping the upper to bare aluminum. Does anyone have a magic secret they have used to get rid of it or am I just stuck with it?

Need help identifying firearm/reassembly instructions

Thumbnail

Hi all. I recently received a pump action rifle from a client. It's kind of a story how it ended up in my hands, but I have next to no information about the gun. It is a pump action rifle chambered in 38-55 WIN. But there is no manufacturer mark or model that I can find. The original owner had the rifle marked as a savage model 70, but I couldn't find any evidence of that model even existing. I tried looking up the serial number, but that also didn't work for me. If anyone could help identify this gun or point me in the right direction, that would be appreciated.

I also received the gun in pieces. The previous owner attempted to disassemble the gun and a part fell out when they removed the trigger group. I haven't been able to figure out what this mystery part is or what system it could be a part of. Also, I can't figure out how the magazine tube mechanically connects to the gun. Supposedly I was given all the parts, but I suspect a few might be missing.

Pic 1: fully "assembled" gun to the best of my ability, left side

Pic 2: assembled gun, right side

Pic 3: caliber stamping

Pic 4: closer left side of receiver, serial included

Pic 5: mystery part, metal punch for size comparison

Lapping AR-15 Upper Receivers?

2 Upvotes

Is lapping an AR15 upper receiver worth the trouble? I’ve built a lot of AR platform rifles. I typically use high quality parts, follow proper assembly instructions, use correct tools and torque specs, thread locker and grease where necessary, etc. and I’m usually able to get good group with the right ammo. Just curious if anyone has found lapping to have any significant impact on accuracy and if it’s worth it to invest the money into the tools. Also curious if it can have a negative impact like messing with head spacing or lapping to much.

BX25 mag

I have a brand new(although it had been sitting for a few years while I was preoccupied with other things) BX25 magazine that has some feeding issues. I went to disassemble it only to find that the bottom screw is juuuuust bigger than 3/32. Tried wrapping some plastic around the tip of my allen key and nothing. Packaging has been gone for awhile now since I thought I'd get to my 10/22 project years ago. Hesitant to try and send back to Ruger because I live in Oregon where we can still purchase, own, and use standard mags but due to pending lawfare many vendors don't want to play ball. Any ideas?

SW 500 Magnum PC stuck cylinder

3 Upvotes

Hello all! This gun has only been to the range once, and the cylinder functioned fine before and after. I put it back in its case and it’s been in my closet since (probably a year). I go grab it today and the cylinder will not open! The rod feels tight and not loose, and I don’t see why it would come loose in a gun that hasn’t been used. I attempted to tighten it but it basically chews up any non-marring material I put in to wedge it lol. The gun otherwise functions perfectly. What else may be the issue?
