What is the gas port dimensions?
Silver on Jan 10, 2019
BEST ANSWER: "Big." PSA errs on the side of full sized porting so that maximum gas comes through. They're not in the biz of fine tuning their stuff...rather then get it out as easy and cheaply as they can and have like 3 people working the company! lol

BroSa on Apr 25, 2019
What grain bullet is best performing in this barrel? I got 62gr match I’m hoping to zero, when this shows up next week.
208Brando on May 17, 2019
BEST ANSWER: Each barrel will like a particular bullet make, weight and charge for precision accuracy. The 62 grain match is a good starting point. I have threatened to take my pistol to a 100 yd rifle match to see if they will allow me to compete. It likes 77 gr. match.

Need better quality checks
Just received my order today, to my dismay I am missing a bunch of pcs. Didnt receive the takedown pins and detent springs. Grip screw and washer, and buffer tube locking ring. You would think they would check a list when placing the parts into the bags. Instead i received 3 bolt lever locks. Sent email guess i will have to wait another 2 weeks for those parts.

simple and effective
always go pistol. except when you want a sturdy buttstock and a 90 degree vertical grip, costs you an additional $200 to the ATF

I ordered this because I always wanted one. The price is super reasonable. The only tool I needed was the wrench needed for the buffer tube nut, the rest I just improvised. Shoots really well with no problems. Looks bad-ass with a 30 round mag.

Paired this with an Anderson lower and completed this “pistol” for $520.00 including the Romeo RD! No complaints so far. Definitely recommend this kit.
