I got the new JP high pressure bolt in and ran it yesterday. Flawless, and not the slightest hint of primer cratering now. Shot off the rest of the PP ammo without incident. Do think I will avoid buying more of that stuff.

Accurate. the upper left group came from cheap Federal 147 gr ammo while sighting in a new scope and experimenting with bench positions and supports. Have yet to shoot match grade ammo through it or try for best groups. Had a scope go weird and been getting back to square 1. Gas block is...

Gun has gotten so accurate, starting to examine everything.

At least 300 rounds through the barrel at this point. After bedding the barrel, it is easily a MOA rifle even with some inexpensive commercial ammo. No cratering seen on mil surplus M80 ammo which is what I shot mostly when I built the gun. Been collecting the brass as I was nervous about...

Pretty much my plan at this point. I did try to do the hook under the extractor thing, but it would not hold on. Got suspicious just what buffer spring I had in the rifle after starting to build a mouse gun. Gof a "Neverwear" AR-10 flatwire spring. Had to tweak the GB adjustment slightly, so...

With an AR, the rotation has to come from the bolt carrier, no way I can grab the bolt and turn by itself. I tried and thought of getting a stick to shove into the firing pin hole to rotate it. Am I missing something?

Been watching that cratering for some time, why I finally bought the JP High Pressure bolt to try. Just off the shelf .308 ammo, no handloads. Some surplus Fn marked ammo does not show cratering. Read that factory ammo is a bit hot in gas guns. Ejector made a faint mark, extractor as well on...

Original bolt and carrier from DPMS. Not shot the JP bolt yet. Rifle length gas, rifle rcvr extension and .308 rifle buffer and spring. JP adj gas turned down to reliably cycle.

Doing some range time with my frankengun LR308. Barrel is a Fulton Criterion 18.5 " mated with old style DPMS Upper and lowers Adjustable gas block. Ammo was Privi Partisan 165 gr. Have had mildly crater primes on some commercial ammo, never on surplus M80. This round sounded and shot...

Re: 308 PMAGS Crazy shiite, a buddy sent me one a few weeks ago as a Chrismas present, said a friend bought it without knowing it did not fit the Armalite. OK, now I have four of the puppies, along with a few DPMS 19 round clunkers. Will stand pat for the moment unless I decide to change to...

Re: Stripped AR lower: where can I NOT send it? Absolutely legal to ship to HI as long as you send it to a FFL. Magazines with greater than 10 rounds may be an issue, but it is largely ignored. If they are sent disassembled even that is OK since they are now just "parts". What are you selling?

Re: Bipod options besides Harris? Sinclair (Brownell's?) and Weaver also sell tactical style bipods you rarely hear mention of.
