Torque spec?

Is there a torque spec when installing a barrel on a Mauser type bolt action receiver? A Remington 700 or Mossberg 810 for example.

Lee Enfield .303 Restoration. I bought this 1942 rifle from a guy with another .303 and a ton of ammo for $150. Both rifles were sporterized so I obtained a new old stock wood set and set about on the restoration.

Remington pre model 11 help

I just picked up a Remington model autoloading pre model 11. It is fully disassembled. Everything is included. I’m trying to find any resources or videos on how to reassemble the gun. If any of you have a video or source you recommend that would be appreciated.

Barrel porting advice

Hi so I am a machinist and I'd like to port a barrel on one of my 9mm pistols. I'm going with several top ports behind the front sight. The slide cut should be easy, but I have some questions regarding the barrel. First, how large should the finished holes be? As far as how many, I was thinking 3 to 5 ports depending on recommendations. Also how should I go about drilling? Would a carbide drill and then a carbide reamer be the best choice, or should I go with something different? Also if it becomes pertinent the gun is a Sig p365xl 3.7" barrel.

AR10 eating case rims.

This is the second time my AR10 has chewed a chunk out of a case rim and getting it stuck in the chamber. Both times this occurred I was running a suppressor which I’m assuming is the cause, just not knowledgeable how it would. It’s two different brands of ammo and I was able to fire 20-30 rounds between the first and the second malfunction both suppressed and un suppressed. What can I do to prevent this in the future?

Kimber M96 Sweden - sporterized

I recently picked up a “sporterized” kimber m96, 308 bolt action. This has an internal magazine. Has anyone had any experience with converting these to magazine fed?

JB weld to fix cylinder slop

I have an old s&w revolver with a bit of wiggle due to some worn cylinder stops. Can I just add some in JB weld to fill in where the metal in the notch has been pushed back to tighten up the gun?

Polishing frame mounted rail points on TX22C

I'm going to polish the frame mounted rail points and clean up the feed ramp a touch. I'm not a gunsmith.

For rail points, does it hurt to use a dremel cloth polish wheel and polish? The rail points are less than an 1/4" so it’s hard to do by hand with 600 grit and cloth. Or, should I use the dremel polish felt tips?

Issue: The slide is closing on the extracted round like a sideways stovepipe. I can feel the roughness in the slide action. I figure a little polish and a reduced recoil spring would do the trick. If that doesn't work, I figure that I'll try a lightened recoil spring. Firing CCI stingers, so ammo quality is not the issue. Thanks

30-06 to 35 whelen

I have a sporterized Mauser gewehr 98 in 30-06 and I want to rebarrel it to 35 whelen. As far as I understand 35 whelen is just a necked up 30-06 to 35 caliber. It would just be a barrel change and nothing else correct?

So today we had a guy bring in a badly jammed keltec PF9

This was so freaking funny. The biggest enemies to guns functioning correctly is almost always the user. The gap in the PF9 is the perfect size for a dime to fit in, but it couldn’t fit back out easily on its own.

Hate being that guy but is this normal?

I didn't notice until just now. When I put A decent amount of back pressor pulling the rifle in i noticed the hand guard seems to Compress slightly and feels under spring pressure. The hand guard is Midwest Industries and has magpul xtm/xt covers. Any insight would be greatly appreciated.

Manual stock manufacturing literature

Fellow weapon technician / gunsmith here. I am looking for literature on stock making. English or German language would be preferred but I am not picky.

Could supply several interesting books or money in exchange.

Looking to replace a Sauer 202 stock on my own.

Got some boiled linseed oil as well as mineral spirits on the outside of the barrel, how does those react to metal? All good?

Just like the title, was refinishing and got excess boiled linseed oil and mineral spirits on the barrel and was wondering if those are fine on metal? I was not mixing the two but during both processes they both got on the barrel and receiver a bit. Thanks

Help building a Remington 778 Rifle, specifically where to find parts

My uncle recently was helping his neighbor empty out her garage after her husband’s untimely passing and he was given some gun related items including a beautiful Boyd’s pepper laminate Remington 778 long action 6mm Remington stock.

I would like to price out building a new rifle from scratch but don’t really know where to start.

I have a few questions as follows:

*Can I use the parts made for a Remington 700 or do I need to use 778 parts? I believe that I can use a barrel from a 700 based on some limited information I could find online.

*If I wanted to chamber it for 6mm Creedmoor or would I need to modify the stock?

*How much gunsmithing is involved in matching components like the bolt and barrel? I’ve built AR’s before, but not a bolt gun yet.

*Where is the best place to buy the parts? There doesn’t seem to be a huge selection of 778 parts out there.

Thank you for your help and responses.

Edit: I realized that I was typing 778 when it’s actually a 788.

CETME C bolt gap

I bought a Century C308 a while ago. It had a ground bolt head but nothing about the operation of the rifle gave me pause. While firing it during my most recent range trip I noticed significantly increased recoil from the last time I shot it. Both with Russian steel cased ammo and hand loads. I just installed an original unmodified bolt head and switched over the rollers and wedge from the ground bolt. My bolt gap is less that .003”. Should I get plus sized rollers, a different locking wedge (currently have a 50* wedge) or both?
