Select. I was mistaken by calling it an intermediate: I meant to say it's a 'medcon', which is a lighter contour. It only weighs something like 33oz. I do not see it currently listed on their website, but they do list the 16"&20" versions of that barrel.

I have the Rainier intermediate Wylde 18" barrel. It shoots MOA with M193 ammo which is not match ammo. It also cycles reliably with an H2 buffer. If it does not run on your 6oz buffer, you'll need a lighter buffer. An adjustable gas block does not perform magic, it just reduces gas available to cycle the rifle.

Shot a steels match suppressed last Sunday. There were no fewer than three suppressed PCC's and I didn't hear of any scoring difficulties.

H4198 at 19-20 grains. It is a fast power so you get good muzzle velocities with low recoil and good economy. I have loaded 335 at 21 grains, I don't get near the velocity or accuracy with this load-- about 2-3 MOA WITH 335 vs 1-1.5 MOA with 4198.

Do you have anti-rotation tabs on your handguard? If not, you might rethink the antisieze, there is no gas tube to keep the barrel nut from backing off. I noticed my handguard backed off a couple degree after a few hundred rounds.

I think SBR's work better on USPSA stages with walls and ports. I have been running a 10.5" SBR for a couple years in 3gun matches. My registered lower is now a converted host to my PCC. My only complaint is the weight of the PCC operating system: it's much heavier than the .223 set up.

I have seen factory Glock 33 rd mags with TTI +10's.

MRO. I have tried TRS-25 and Micro H-1. I have an Aimpoint PRO on my .22. The MRO has the least silhouette of those listed, it's about the size and weight of the TRS and micro H1 with the window of the PRO.

I have a POF drop in trigger. It works wel with no doubles or light strikes, but little take up or reset and I forget to pull it. I have a polished milspec with JP springs in my M&P 15-22 that I can run a lot faster at the steels matches I shoot.

Mine have not shown to be that consistent. I am using a Lee disc powder dropper. I do like the Prima V for its economy.

Do the Glock mags require less spring force to strip and chamber the round? I'm using a Colt set up. I tried the heavier spring with a carbine buffer and my times were a lottle slower with a looser grouping. Also charging the rifle with the heavier spring required a lot more strength.

What does it do to the brass? Is it reloadable?

I shot mine today with the silencer, I was at the range timing myself, I usually hang the timer on my belt, but it wouldn't pick up the shots. I had to put the timer on the bench in front of me uunder the muzzle to pick up. In a couple weeks, there's a falling steel match where the rules specifically allow silencers. I'll post results then.

Shooting my first match tomorrow. Should be no reloads fortunately, I have a Rock River conversion in my Sbr. The reloads require a good tap to seat the magazine. My hopes had been that it would be as simple as shooting .223, but that's not the case on the reloads.

A couple weeks ago another guy on our squad had a case separate on him in the chamber. Fortunately my wife was also shooting PCC, so we just let him use hers. A spare gun might not be a horrible idea. I usually carry a limited pistol for back up to my carry optics gun in case of catastrophic failure.

Same here, have to spank it on a closed bolt--that goes even for a down loaded mag. I have the PSA mags in a Rock River mag block, the block and mags are very new, maybe a thousand rounds through it.

For blaster ammo through a suppressed SBR, try 19gr H4198 with 55gr FMJ @2.20". This load is low pressure, low recoil. It mght not group well beyond 50 yards, but it's a gentle round that won't put a bunch of gas in your face.

Doesn't help with recoil much, but puts a big grin on my face.

I did some more tweaking tiday and went back to the AR15 carbine spring with an H2 buffer. I tried a combination of AR10 and AR 15 carbine springs mixed with carbine, H2 and 9mm buffers. With a target set at 15 yards, I did some timed double taps. I found ultimately with the AR15 carbine spring and the H2 buffer my times were a little faster by about .1 sec and the hits were about 1"-1.5" vs 2"-3" with the other combinations. The noticeable recoil was negligibly less too. Other advantages are it's much easier to charge the bolt, and since there are more coils on on this spring there is overtravel.

Get your reloads down. That appears to be the downside of these guns.

Right now AR-10 carbine buffer with 9mm buffer and a stack of quarters. The bolt has a lot of overtravel behind the bolt catch, so I may rethink this: the AR 10 spring has fewer coils than an AR15 spring, it is also much stiffer and my wife struggles with charging it.... but it shoots well with this set up.

I had the same experience with the Troy ambi on a Rock River mag block conversion. Too bad....

Some of the 9mm AR makers recommend against anything other than milspec triggers.... Thanks for the write up.

Two shooters ran our Rock River mag block conversion in a 140 round match without a single hitch. Also about 500 rounds testing, sighting and tuning it this week.
