lapping

I have a Howa 1500 LA, that I have put about 300 rounds through, but I have cycled the bolt quite a bit to run it in. But I have noticed right behind the one lug, the bolt has a wear mark that I'm not sure is supposed to be there. See pictures. I'm also wondering if I should lap my lugs, since...

I bought a Seekins MXM Cantilever scope mount to pair with my Vortex Viper PST II 5-25x50. Since the purpose of this build was a long range gas gun do I need to lap the scope base? I’ve heard you should lap the rings, but I’ve also heard quality rings shouldn’t need to be lapped. I would like to...

Hey guys, I know you’re all sick of these threads. I know there are a lot of guys pro & a lot of guys against lapping receivers. After going back & fourth I decided I would just go for it & ordered a brownells lapping tool. When I first received the tool it seemed like it had slight burrs & I...

First time lapping lugs myself. Just wanted to check to make sure it looks like I have full engagement on both lugs and also ask if I should switch up to a jewelers rouge to polish the engagement surfaces a bit or just leave it be and let it self "polish"? Thanks for looking.

So I've been doing a lot of reading and lurking and picking up a lot of useful info. So a big thanks to everybody on the forum. But along with reading I've been doing some thinking, and couldn't find any posts on this topic. I've been reading about scope lapping and think it seems a good...

Gents, I've got a scope in a set of good quality scope rings, on a good mount. Had some issues at the range today that would suggest that the scope was bound and/or that the mount was in a tweak. Basically the rifle patterned like a shotgun (this rifle doesn't even do that with irons), and...

Hey Everyone, Would anyone happen to have one they would be willing to ship to me to use for a 'rental' fee? I can pay shipping both ways. Thanks, Jake

I see kits from Wheeler and Kokopelli that offer scope alignment tools and lapping bars. Of what real use are the alignment bars if you have to use the lapping bar anyway to fix any misalignment? Why not just drop in the lapping bar and fix what the alignment bars would have shown needs...

Would you bother lapping the factory barrel on a precision .22LR (specifically, a Savage MarkII FV)? I ran some searches, but did not find anything specific to rimfires. Thanks in advance.

Should I? Should I not?

When you guys lap your rings do you do until the alignment points are exactly lined up or very very close? Mine are within a millimeter of each other vertically and lined up horizontally. I don't want to take off excess material if I don't have to. Thanks. Tom

I was testing out the engagement of the lugs on my factory .338 RUM - degreasing the bolt/action, covering the rear surfaces of the lugs with black magic-marker, inserting a fired case and working the bolt up and down. Then pulling the bolt and seeing how much of the lugs engaged (scraped off...

I was wondering what in your opinion is the best lapping compound. And correct if i am wrong but dont you just put some on the locking lugs and work the bolt a few times?

Is there any disadvantage of lapping your lugs with your firing pin in and letting the tension of the firing pin spring lap your lugs? Please advise.. Thanks

Another forum (6mmbr.com) brought up a point about hand lapping factory barrels. The general idea seems to be a plastic bristle brush, some 0000 steel wool and JB Bore paste. Put a plastic or wooden stopper in the muzzle so you don't pass the lapping equipment through the muzzle. Count 50...

just got a pair of 4 screw seekins rings. I CANNOT easily rotate my us optics sn3 in them without scratching the scope body. Has anyone lapped their rings before?

So I will be mounting a Leupy Mark 4 in some Seekins rings on my Remington 700 in a week or so. I don't have a torque driver so is it possible to gauge it fairly close without? I am familiar with torque wrenching and I think I could guess pretty dang close but does anyone have any tips that I'm...
