2019年4月22日 · I left the PSA spring, because I ordered a SI bolt catch and will put the Spike spring when I swap the Bolt Catch. But as I predicted, the roll pin holes line up perfectly. PSA and Spikes are nearly identical lowers. “Linkage - Bolt Catch (9mm Glock)” part # NSP2364 And “Support - Bolt Catch Linkage (9mm Glock)” part# NSP2365

2024年10月12日 · The PSA AK-V has a 4150 10.5” nitrided barrel with a 1/10” twist, threaded 1/2x28 to interface with most common 9mm muzzle devices and suppressors. This PSA AK-V comes equipped with an ALG AKT Enhanced Trigger With Lightning Bow. The AK-V was tested and performs well while being suppressed, and is rated for +P+ 9mm ammunition

2023年2月15日 · I did the same thing. I knew PSA had a reputation for over tight barrel installation. I contacted PSA and was told they would only take the barrel out if needed for service. They would NOT remove the barrel and send the separated parts back to me. So, I tried if my self. PSA definitely over torques the barrel installation.

2020年5月8日 · I have one of the PSA 9mm uppers and I wanted to swap barrels to a shorter barrel and new rail, but am perplexed at the barrel nut. Is there a special way to get these off? I had it in the barrel vice practically leaning on it and it didnt budge.

2022年8月8日 · These are MRDS's PSA has verified to be compatible with the Compact Dagger TM RMR-cut slide. A Holosun HS407/507C X2 will fit, as well as other HS407/507C variants. Any MRDS compatible with the Trijicon RMR footprint will directly attach to the Compact Dagger TM RMR-cut slide without an adapter plate.

2019年5月23日 · FWIW- My PSA AR9 ran 100% reliable out of the box with all mags (factory Glock 17s & 33 rounders, ETS 30 rounders and PMAG 17 rounders) so I am not bashing PSA. They delivered a fully functioning 9mm AR for a very reasonable price (no small feat on its own). I simply wanted to tweak the gun to run smoother with quicker, on target, follow-up shots.

2021年5月8日 · I meant you put a 1/2-36 to 1/2-28 adapter on the PSA 9mm barrel…so that firearm and all your pistols have 1/2-28 threads. I don’t have an Obsidian, but based on the cans I do have and the pics of the Obsidians I’ve seen, I believe it’ll …

2024年1月18日 · And the PSA mags are really cheap, like $15. The 7" gun has the SB PDW brace, and an aluminum handguard that resembles the MP5, and a tri-lug muzzle device. All cosmetic. If you like it, get it. I was on PSA yesterday or the day before, and most of the ARV's were in stock again, so I don't think they are discontinued.

2019年7月1日 · I got 2 of the spartan upper with the charging handle in the back. One on 9mm and one on 45acp. Right out of the box, it works with glock mags 100%. I had to slightly bend the actuating arm thingy to get it working with magpul and …

2020年8月21日 · PSA does not show any affordable 9mm BCG's on their website. I was ready to order one from "Dirty Bird" when I received a PM from Josiah. He indicated that they will ship me a BCG.
