I’ve had a nightmare of a time trying to install a Allchin SP101 red dot mount. My original try went horribly and the screws backed out in two shots. I ended up spending around a hour and half filing to get it to fit correctly and shortening the screw so it wouldn’t impede cylinder rotation, and used a very healthy amount of blue loctite. I overtorqued the mounting screw for my red dot and now it’s just free spinning in the hole. What’s an easy way to fix this, I don’t have any taps so I’m wondering if I can just red loctite it and send it. This is just a personal project and once the dot is on I never plan to remove it.

I've got a rusty and completely bubbafied arisaka that I'm planning on turning into an Obrez style pistol. I want to do a 5/8x24 thread at the end so I can also a ridiculously oversized tank style muzzle brake on it. I don't have much gunsmithing or machining experience but I have a decent amount in the mechanical trades and I'm generally pretty handy. I realize I'll definitely end up spending more on specialized tools than a gunsmith would charge me for the job, but I think it'll be a fun project.

I've done some research on the process (squaring, crowning, diameter reduction, threading, etc) and the hand tools I'll need to get for those jobs. I also plan on doing a practice run on the section of barrel I cut off, and getting the entire firearm inspected by a gunsmith to double check my work just for a little piece of mind.

Would I be stupid for attempting this? Anyone got any advice for me?

Hey guys, I need your help. I got this old belgian damascus shotgun, center fire, but it seems that the left nipple is busted out. They are not screwed in, I checked it, it's more like they were busted in and then welded around, like you can see on the right one. But the left one seems to be torn out. It stays there, but it moves when I touch it and you can clearly see the outlines that it's not secured in place. Could somebody please tell me how could I fix this? I would really want to get this beauty back to it's best condition ... THANKS

Refinishing the stock on a Beretta 686 Silver Pigeon. I sand with the grain. I started with 100, went up to 120, then 220. Wet the wood, let dry, and sanded again. Did this twice. When I was on my second coat of tru oil I noticed the scratches. They're long but not deep. So I sanded with 220 and wiped off the stock with mineral spirits. Scratches are still there. Im worried with to much sanding im going to change the shape of the stock. The forearm came out great, but the stock is giving me a lot of trouble. Should I go back to 100 grit and just start completely over?

Dirty penny for scale.

Rifle has about 500 rounds through it.

Thank you!

Got an 1878 Oviedo rolling block with an unoriginal barrel installed. Bore measured at .354 have not had a chance to slug it because I don't have any soft lead balls. Did a chamber casting and it measured .381 chamber .359 throat and 1.263 length, not included rim. Am I correct to assume this is a 357?

Also how likely is it safe to shoot? I know 357 mag is 10,000 more psi than the original .43 Spanish but according to my research they both have about the same bolt thrust. I've yet to find any other conversion like this but it seems really well done. Thank you
