I don't have any cold hard numbers on the wear factor, just a working knowledge of brass and steel. With what I have invested in my barrels, I don't want the wear that will result from shooting steel cased in it until the barrel is worn to the point that chamber wear won't influence accuracy or repeatability. I want my chambers to wear as little as possible for as long as possible, and brass is far preferable to steel in that respect.

... and now he can see noises! <laughs> <lmao>

Well, if you're gonna twist my arm... We start with a center drilled piece of 316SS bar stock.. Step drill it up a little... Bore it out to .800" with boring bar... Now cut OD to .936" to match gas block.... Cut 20 degree angle at front per drawing... I don't have any pictures of cutting the 45 degree chamfer in the rear, but it was very simple, and finally pictures of the finished product.

It's together! The beast is finished and will see it's inaugural test firing tomorrow afternoon! I took some pics of the process too, gonna try and get them uploaded to update the thread.

*Crosses arms and begins with a know-it-all tone of voice* I'm very partial to my Ops Inc 12th Model (30 cal). Of course, I haven't even shot it yet, and really have never even fired a suppressed weapon in my entire life, but I'm very partial to mine... <laughs> <lmao> <thumbsup> Seriously though, tomorrow that is all going to change, hopefully.

I've spoken with George, not a whole lot but enough to be impressed with what a nice, knowledgeable guy he is. I wouldn't hesitate to use their services for anything.

There's a 1k range at Butner, NC. That's about 4-5 hours from me, I'm in the southwest part of the state. Welcome to the forums brother!

I wouldn't for one very simple reason, and that is chamber wear. It's going to be far more aggressive with steel than brass.

Uhm, is it a vowel or a consonant? :help:

Crickets & Tumbleweeds bro, gotta learn to love 'em!

This made me laugh out loud for quite some time. Thanks for making me feel better.

The typical 308 AR isn't piston driven (though a select few are), rather are Direct Impingement systems and thus aren't as adversely affected by overgassing. Semi-autos like the M1 and it's variants can be sensitive to the issues you are talking about, but the average large-frame AR probably won't be unless it's a piston-driven system. I'd venture to say that outside of shooting suppressed, off-the-shelf ammo won't be a concern with regard to a DI gas system.

The answer to all of those questions is a definite and emphatic NO. You should be far more wary of shooting handloads through your 308 AR than off-the-shelf ammo.

Man am I relieved to hear you say that, I've had the same concerns of late. Bringing the topic back on track literally greyed a few of my hairs, I'm pretty worried about him too.

Yessiree! I want this on a t-shirt STAT!

*insert 45 minutes of purple faced cursing here* It just simply didn't happen today. I got to the shop ready to do my bit, and the whole thing fell apart piece by piece, and ended up with the machines being needed for work more pressing than mine. So, it looks like I'm going to be making attempt #2 at this project next weekend. Dammit all!

You're right on brother, 20 degree taper and a minimum rear shoulder height of .920. The collar is going to be .936 so that my gas block will still slip over it with it in place, has a female 45 degree chamfer in the rear to match the profile of the front of the gas block shoulder. Overall length is 1.066 and on the front is the 20 degree gas seal taper coming rearward. Here's the drawing that Daniel Dregne sent me:

I'm going to the machine shop tomorrow to cut the taper attachment for my barrel so I can attach my suppressor. This has been a long time coming, and I'm really excited. Keep your fingers crossed that I get the part right on the first go. If it all goes well, I'll be updating my suppressor timeline thread with some range pics/video.

I'll send you a PM with further instructions... <thumbsup>

Hot diggity! I'll take the one on the left... You guys can fight over the rest!

It just has to be a picture of your actual item, it doesn't have to be eligible for any awards.... :) If you have pictures, we can walk you through getting them on here.

Medic, do you have any pictures of the item?

I noticed the same thing, but it looks like it makes the charging handle more accessible that way, which leads me to believe it's intentional.

Hey this would probably do great in the for sale section, just add your picture to the post and we'll move it there for you.
