That sucks, Rick - that leave Ed right out. He's no "normal man..." <lmao>

^^^ He has issues. <lmao> Only 1 is his, and the rest belong to Char... :banana: My Fulton/Criterion 18.5" stainless MW contour rifle gas barrel does it, all day long, with minimal effort from the trigger puller. The Rainier stainless 18' Select does it, too, on mid-gas. I haven't accuracy tested the Faxon Firearms 16" mid-gas yet, but it'll get tried out for groups. I don't think it'll be over MOA, based on the initial shooting of it. Another damn good barrel. The Fulton/Criterion and Faxon barrels are 1:10" twist, and the Rainier is 1:11.25" twist.

Yep. They make a bitchin' GoPro mount for a pic-rail, too, and I need to pick that bastard up.

Just a couple points - with that bolt half-way rotated like that, attacking it from the muzzle end would have broken parts, i.e., put a rod down the barrel and try to tap it back to unstick it. What you did was probably the right way to attack that problem. You needed the bolt to fully rotate first, in order to be backed out of the barrel extension - the only way to do that is make the carrier go back, and the cam pin will unlock (rotate) that bolt from the barrel extension lugs. Mortaring, as Robo suggested right away. Always make sure your stock is fully collapsed before you mortar... Say you shear the case rim off, the BCG comes back, and the ripped up piece of brass is stuck in the barrel chamber - that's when you'd need to attack it from the muzzle end, and knock that stuck brass outta the chamber. Had you tried that in your situation, you would have broken off some/all bolt lugs... Lastly - I didn't see you mention that you checked headspace on this build... I'll just leave that last one there. <dontknow>

Called. Out. That $hit just happened... <lmao> :wwop:

You are the AR Gunsmith's dream come true - any info you want to share is more than welcome. I still think the "308AR/AR15 Armorer's Course" would be the ticket. <thumbsup>

Try CNCGuns.

The possibility of debris in the firing pin channel could have held the firing pin forward, forcing it into the primer, instead of just lightly bouncing off the primer. I've noticed in 5.56 rifles - alot - you chamber a new round from a fresh mag, using the bolt release. Pull the round, check the primer, slight, small dent. Not enough to set it off, but enough to let you know that it contacted. Militarily, we'd go through several rotations where we'd chamber a round, only to unload and clear later. What do most people do? Pop that pulled round right back in the top of the magazine... It's only gonna get chambered soooo many times before it gets popped. I always made my guys rotate that pulled round lower in the mag, and always check the top round to make sure it hadn't been chambered before.

If you're just talking about the PRI pic-mount flip up (for a rail, for example), then you can use any one (not the crazy-height picatinny gas block sights, though). There's more than enough adjustability in the front sight post to account for a minor height difference. If you should fall short, a few companies make front sight posts that are 0.100" taller than standard. Don't think you'll have an issue, brother.

That is the plan - anchor it down in the drill press. Looking at that, and the way they taper down the hole diameter from back to front, I'd have to wonder if I'm changing the effectiveness of it. They designed it like that for a reason, and I'd change that, boring straight through.

It says 100 because you're THREE times more badass than The 300... :hail: Robo, The Lord Of The Lap Dance, can change that to anything you want - and sometimes something you don't want... <lmao> (Watch out for Matt, too. I'm just sayin'...)

Excellent build, by far - it's badass. Like to see some more pics on those mags, and your thoughts on them compared to others. You knocked that one outta the park, man. <thumbsup>

You ever shot more than 40 rounds through your 7.62x39, yet?...

Never, ever any need to polish the trigger and hammer pin holes in the receiver - ever. Don't even know why that thought would even occur. Have no idea, either, why you'd polish the holes in the trigger itself, and the hammer itself. Where the hell did you even hear about anything like that? That might be your very problem. You increase the diameter of the hammer pin hole in the hammer, and you give the hammer "flex," and room to move where it normally doesn't. Same with the trigger pin hole in the trigger and disconnector - more movement. Before you know it, you just fucked with your disconnector sear to the hammer... Boom. $hit can that trigger, try something else. Or, take that thing back out to the range and try to get it to fire again, just by releasing the bolt catch. And observe the trigger/hammer again. Also, before you get all pissed off and butthurt about the info presented - this isn't our first rodeo. There's a bunch of smart fuckers here, including gunsmiths, asking you questions, and the answers aren't adding up. I can't even tell you the numbers of rounds myself, and very good friends, have launched from DPMS-pattered 308ARs, and never, ever had a slam-fire. That even includes Mike's crazy $hit. You need to look at that trigger work you did, get that thing out of there, and try something else, stock and unmolested.

$hit. Might be going with the Griffin... Thank you much, for the additional info. <thumbsup>

The stencils, or the Aervoe paint?...

I don't own an AR10, either - don't want you to think I was brand-bashing, because I'm not. I'm just pointing out exactly why Armalite does that in the big AR, and that's the only reason they do it. Are you positively sure that your hammer was still in the cocked position after the slam fire? Positively? Meaning, you specifically checked that the hammer was still locked down/back after this thing went off when the BCG went forward?

Awesome, brother, that would be great. <thumbsup> I'm currently debating between this one, and an offering from Griffin Armament, to see which one gets bored.

It'll read something like this, I imagine... <lmao>

DSG usually stocks the Aervoe paints - love the stuff. Same stuff I used on the Savage FV-SR. <thumbsup>

Spartan - I'm starting to look for a dedicted .338 brake or comp. Do you think there's room at the end of this device to bore the exit hole a little larger than .338"?... Any other obstruction between the barrel muzzle and the end of this device that would need attention?

If it's truly a slamfire and not any other kind of mechanical malfunction... This is exactly why Armalite uses a firing pin spring in the AR10.

Gonna miss you, Micro. Really gonna miss ya. GoodSpeed, brother.

There's also the very strong possibility that you're using the term "double-feed," just because you have something stuck in the chamber - and it's not a true double-feed. You have two live rounds trying to enter the chamber at the same time, Eddie?...

Depends more on how you treat your magazines, than round count. Double-feeds are always magazine related.
