UPDATE: The kids and I had a range day with a number of guns including the PSA AR-9. Put about 200-300 rounds through it. No FTE or FTF were noted except for a couple occasions where the magazine was not inserted completely (not me!
). The kick was similar to a .223 AR.
The Glock-compatible magazines seemed to function well, and are from ETS (
etsgroup.us). They are 31-rounders and picked up in a "package" from PSA. We had 2 in the rotation and I think I paid about $10 each in quantity. Of note is that there were only 25 rounds loaded as that is half of a box of ammo and was just more convenient for the kids to load. A Glock loading sleeve helped with that... The mags also functioned perfectly in a G26 that was in the rotation.
Before the trip I installed MBUS sights. The MBUS were dialed in near perfectly as received from PSA (bought on sale for $50 inc. S/H) and the kids were nailing cans on the plinking range from 75' no problem.
I also converted a spare A2 grip into an A1 but a Hogue grip (without raised backstrap) will be going on soon.
The last mod planned will be replacing the "regular" AR upper with a 9mm version. I hope the handguard matches the new upper... The FA is superfluous in this gun with the bolt used and the upper will simply be used for a different build. I picked the upper up from Thunder Guns in Daytona (
thundergunsar.com). I was there picking up some anodizing from their sister company DEC. Also got a few other goodies!
(300BO 16" w/FH, adj. GB, carb tube, anodized U/L 80s) Great group of people to deal with!
