Ive been using gun oil, clp, and a brass brush but it's pretty badly rusted shut. I am not against some more harsh treatments or refinishing the gun as it is already pitted and I don't aim to sell it, just get it looking better and functional.

Need help with a Winchester 94 from WW1

Post image
5 Upvotes

Hello Reddit community, I'm a French user and I've acquired a Winchester 1894 from WWI, used by the French army. My father and I found all the parts to restore it, but one part is completely broken: the hammer spring. It's impossible to find anywhere in France, and I saw that it's in stock in the USA, but I can't have it shipped. Could someone help me get this part so we can restore it?

The part is cracked, here's the photo, and it's impossible to repair it yourself.

Thank you! 👍

Anyone Seen This Fox Before? Deagle Mk1

Post image
16 Upvotes

This is a mk1 Desert Eagle from 1984. Very early production. Can anyone identify what I’m seeing here on the frame? It almost looks like polished welds or something. Very odd. Let me know if you know anything about what this might be as I’m looking to potentially buy this. Btw if it’s not obvious, this is directly below the barrel under the slide.

Oversized chamber concern

I picked up a Radian ramjet for a sig365x and had a few concerns, I was hoping some one can verify if this is safe and common for radian or if rep at radian is full of it.

  1. Uneven brass expantion up to 10.03mm with a buldge near the base.

2.un-even carbon fowling on brass and chamber wall at 11 o clock position. Ferthest most brass to the left was shot from the OEM barral

  1. Rounda exceeding 1000fps are being thrown verry low left not even close to the target ( might be me but no issues with 900pfs rounds or anything from the OEM barral.)

  2. visibal ring around the neck of the brass fired from radian, it was explaned it is intentinal to provide a better seal. Seams reasonible but dose not appear to be working.

Thanks.

There's this design of the Malorian that I really want to try and make a 3d print prototype, but I wanted to ask what improvements can be made on it so I can try and add it to the plastic prototype, just so it can cycle dummy rounds. (I did not design this myself, the credit goes to OnyxPlateau)

Building my First AR-15. Need some pointers on proper tools.

1 Upvotes

Hey yall. I am dabbling with the idea of building my own ar-15 using a complete PSA upper and a stripped psa lower with their magpul lower part kit. I’m wanting to buy all the tools I could possibly need before starting to buy my components. What are some stuff I would need? My upper is coming fully assembled with a charge handle and bcg already installed so all I’m assembling is the lower portion. Thanks for yalls help in advance.

Home made shot gun?

2 Upvotes

Update I did a lot of research last night and found a solid choice for the barrels. I found a company near me that makes seamless 4140 steel tubing and does custom orders. So the plan for that is a pair of 28 inch tubes with a I’d of 18.5mm and a wall thickness of 1/4inch.

For starters this is perfectly legal in the state I’m in and it is mostly going to be for display but I’ve been doing research on how to make shotgun out of parts from a hardware store and I wanted to get some advice before I even start drawing it up so here are my questions

Has anyone tried this if so how did you do it? what’s the safest way to test it? how thick would a steel pipe need to be to handle 2 3/4 target loads ? Would I need to worry about tapering the chamber side of the pipe? Should I port the muzzle end? And is longer better than shorter? My ideal plan is to have with 28 inch barrels and another 20 for the stock. Would 18 inch barrels be safer pressure wise or the 28? Not trolling actually serious about designing and making it

Savage 720 repair opinion

Thumbnail

24 Upvotes

I picked up 2 Savage 720s over the weekend. It is late 30s and appears to operate as it should, but it has a cracked handguard. The other one is ww2 and has a broken charging handle, roll pin, and cracked barrel ring thing. I can't justify taking the complete operating one apart, and I can get the parts I need. BUT main question: What would you do to fix that barrel loop that rides on the magazine. Weld it? Silver solder it? Replace it(no idea if possible)? I would like to keep the correct ww2 barrel on it.

Aftermarket stock fitting issues

1 Upvotes

Need help with Savage 110 Tactical + Boyd’s AT-One stock installation
I have a Savage 110 Tactical with an AICS-pattern magazine, and I recently installed a Boyd’s AT-One laminate thumbhole stock.
I’ve run into a few problems and would appreciate advice from anyone familiar with this setup.
After installing the Boyd’s stock, my trigger became extremely stiff and barely moved, almost like something was physically blocking it.
I noticed the magazine hinge/trigger-guard area was contacting the stock. I had trouble getting the long threaded action screw out because the hinge was in the way.
The hinge is held in place by a small hollow-looking pin that appears to be a roll pin.
I carved out a small amount of material around the area where the trigger was interfering. The trigger now works, but the bolt has become extremely tight.
I’m wondering whether the action is binding in the stock, whether the action screws or magazine-hinge assembly are causing the problem, or whether this stock requires a different fit or hardware.
My questions:
Has anyone installed a Boyd’s AT-One on a Savage 110 Tactical and run into similar issues?
Is the magazine-hinge assembly supposed to sit flush in the stock, or should there be clearance around it?
Could the stock or action-screw fit be causing both the trigger interference and the tight bolt?
What should I check to make sure the stock is compatible and the action is sitting correctly?
I haven’t fired the rifle since these issues started. I’d appreciate advice from anyone who has experience with this exact setup. I can post pictures of the hinge, stock inlet, and trigger area if needed.

1942 Winchester Model 12 Bluing Questions

Thumbnail
gallery
8 Upvotes

I recently purchased this Model 12 16ga Full choke for bird hunting & sporting clays. Well, what I and the shop thought was a 50's-ish build date, at a price I couldn't walk away from, turned out to actually be a 1942. I'm not wanting to totally restore it, as it's got a lovely charm. I'd like input on rebluing, or atleast how to protect and bring some life back into it.

The trigger group was the worst of it, evidence of it having sat upright, the guard's bluing is all but gone and light surface rusting has occurred. The magazine tube, along with the band missing a screw (Which I've already sourced the parts to repair), has the heaviest wear to where the pump rides. The barrel, particularly the muzzle is also in rough shape, I cleaned the surface rust off, but, the bluing is gone, there's heavy scratches at the slide.

I was considering the Birchwood Casey kit, but would be open to ideas, again, I'm not wanting to totally reblue it, just bring some life back, and protect it. Also, any input on what kind of paint to use to re-red the safety?

I recently acquired this ar from a family member. Broke it out this afternoon to take a good look at it and she's well past a little dirty. There's this sticky gunk all over it that gun scrubber ain't working on. What can I use to get a better clean. The stuff on the barrel is pretty much hard but will flake off a little. I'd imagine its been hot a time or two.

Rear sight blade.

I asked S&W as well as Bowen Classic Arms and sadly couldn't help me. I'm trying to source a .222" tall rear sight blade for my model 29-3 silhouette in .44 magnum. I bought it last year knowing the blade was broken. The rear sight base seems fine still. Can anyone help me out or perhaps point me towards someone who could make one?

Plumb Bob Best Scope Leveling Method??

3 Upvotes

I’ve used just about everything (spirit levels, Arisaka leveling tool, feeler gauges, eyeballing it, etc.). Currently mounting an older MK4 that was visibly off when using the Arisaka leveler due to the shape of the body. Is a plumb bob and flashlight my best bet or is there something more reliable? I know nothing is ever truly perfect but I wanna get as close as possible.

Beretta O/U ejector slow acting

3 Upvotes

I shot about 8,000 rounds with my Beretta 686. The ejector on the upper barrel works fine only about 90% of the time if you open up quickly. If you do it a little bit too slow only the lower barrel ejector spring will eject the spent shell, the upper one stays pushed in and will eject a couple seconds later while you‘re already trying to get the shell out with your fingers. As one can imagine that is quite annoying.

Now, I‘ve cleaned the bloody thing with brake cleaner and got quite a bit of dirt out. I‘ve flooded it with gun oil on several occasions and pressing the ejector in it comes right back out with no resistance or scratching. What else could I do?

Also I‘ve had on a few occasions now, that the upper barrel will not fire after shooting the lower one. There‘s no imprint on the primer, the trigger just doesn’t do anything. It almost feels like the trigger is blocked.

I‘m usually only shooting single targets so not that problematic but still not like it‘s supposed to be.

Any advice?

New Build Advice

1 Upvotes

Built out my first 300 blk AOW and trying to diagnose why my bolt won’t lock open on the last round of my mag. For reference, I am using an Andro Corp upper with an 8 in barrel and using an Armaspec SRS gen 4 H2 weight buffer system. What I find weird is that the bolt does actually lock open if only shooting with one round in the mag but not if I load in more. It’s tough to gauge ejection timing because I only have access to an indoor range but I am noticing the casings landing on the shooting platform and some behind me so I think it might be under gassed. If I swap out the weight to the “H” weight, could this lead to a catastrophic failure if I’m wrong about it being under gassed?

Trinidad State Summer Certificate

2 Upvotes

I've been taking machining, welding, and a few carpentry/furniture making classes at my local community college (Integrated studies degree) and I've been looking into the summer technician certificate Trinidad State offers. I might do the custom pistolsmithing and NRA safety instructor course as well if possible. I have the GI bill so tuition isn't a concern and I won't have to take out any loans or anything to support myself. I'd like to get into gunsmithing, but even if I just end up using what I learn for my own projects it's not the end of the world to me.

Has anyone here done any of those three certs? Would you do it again if you could go back?

How specialized is the pistolsmithing cert? Did the skills you learned translate much to other firearms?

General Trinidad questions: How was living in Trinidad and what's the school like?

Rusted bore on a Mosin Nagant can it be saved?

I have a Mosin Nagant that my brother used corrosive military surplus ammo then put away without cleaning it. It sat in the safe for about a year.

I’m hoping to save it and would appreciate recommendations for cleaning products or methods to remove the rust. Has anyone dealt with something similar?

I’ve already ordered a carbon fiber cleaning rod, .30 caliber and 8mm bronze brushes, and bore mops.
Any advice would be appreciated!!

P.S. Lesson learned my brother’s Mosin privileges have been revoked.

Chassis Prototyping

1 Upvotes

Hi All,

Over the last year, i've been on-and-off developing a precision chassis for one of my rifles.

I've been prototyping with my 3D Printer and I'm at the stage where I'd like to start an aluminium (or alloy whichever is cheaper at this point) prototype, however much like 99% of the population I don't own a 5-axis milling machine.

Has anyone done anything similar and can recommend a company that I can send the files to, have them manufacture it, and ship it back to me?

Edit: ideally, somewhere in Australia
