And now, the moment we've all been waiting for... maestro, drumroll please...

TA-DA!

Finally got the last few little incidentals. Got to shoot them last weekend, get some kinks ironed out. Waiting on a Wolff extra-power hammer spring to resolve some light primer hits on Wolf ammo, but other than that (and the hope to someday add a red-dot to each) THEY'RE DONE!

Ok here are some of the specs -

Both rifles have Stag lowers, Sun Devil billet uppers, Magpul MOE grip, forend, and rear sight, JP adjustable gas blocks, Truglo fiber optic front sights, and BCM Gunfighter charging handles.

The 5.56 (OD green) has a Bravo Company stainless NM barrel, FailZero bolt & carrier, Magpul MOE buttstock, JP "BENNIE COOLEY" muzzle brake.

The x39 (FDE) has a chrome lined barrel, SMITH ENTERPRISE muzzle brake (thread adapter required), VLTOR E-Mod buttstock, YM chrome bolt carrier, and MGI Enhanced Reliability bolt.

Took me a while to get all the parts together (nearly 4 years). Yes, I punted and had the assembly done by Sacramento Black Rifle. They did all right, but did not lube any of the parts or test fire the guns. I suppose that's my bad, I did not ask them to provide oil, although I would have thought that would be pretty "standard" when putting a new AR together from parts. On the first range outing I forgot about the adjustable gas blocks and had rounds stuck in the chamber and short stroking. Next range trip, I remembered the adjuster tool (just a small allen wrench) and put some FrogLube on a spent shell and worked it in/out of the chamber until that was all nicely coated. No problems on the second range trip, except the Wolf ammo issue. Very happy so far with how these turned out.

While I can't say they're truly "finished" (need a good red-dot for each of them) at least for now they are USABLE. Good thing, I have a carbine class next month and am counting on at least one of these to get me through that.

which brake did you go with, the cooley or the other one?

Also, what is the breakdown of specs. I can see most of it, but who made the barrel, BCG, etc.

Whats the purpose of the rear sight being further down? do you have better target acquisition that way?

Clean and simple I can dig it!

When the Magpul BUIS is all the way rear, when folded down it interfered with me getting a good easy hold on the charging handle. Maybe more of a perception than an actual issue - so I moved it forward to compensate... maybe overdid it a bit. For now, I'm letting it ride. Might change it later.

The Wolff XP hammer spring arrived and I got it ("ummmmpf!") installed this morning. Hopefully a range trip this weekend will tell if the occasional misfires are resolved now. Wish me luck.

Sorry, should have followed up sooner.

The Wolff XP hammer spring did improve the situation by about half. Still too many fail-2-fire for a defensive firearm. My last hope before abandoning Wolf ammo is the Model 1 Sales enhanced firing pin. I have one on order now.

Hopefully that will be the icing on the cake that fixes the issue. I'll try to check back after the next range trip with results. Wish me luck.

Mil spec trigger?

Have your tried lightening the hammer?

Lighter Hammer = higher velocity when it strikes the firing pin = no more light primer strikes.

Simple mod, you can do it at home with a dremmel, a grinder... took me like 2 minutes with a table grinder.
