PSA 9mm Glock Style AR15 Lower Receiver | PSA AR-9

Palmetto State Armory aka “PSA” has embraced pistol caliber AR’s in a big way. In the case of AR 9mm they offer them in Colt and the subject of this post Glock Magazine compatible style. PSA is currently offering no less than 20 different options of 9mm AR-15 lower receiver. Now that number is slightly misleading because PSA also includes 7 blemished models as 9mm AR lowers for sale. The 13 9mm lower receiver models that remain are actually PSA’s way of having a 9mm AR lower your way. They offer basic stripped 9mm lower receivers, 9mm AR Pistol Lower Receivers as well as variations with different stocks and triggers. Examples would include SOB Brace, KAK SHOCKWAVE, Magpul MOE Furniture and EPT Enhanced Polished Trigger.
