This little AR 9 is well worth the money you won’t be sorry. PSA makes excellent weapons.
One of the nicest AR 9 I have EVER SHOT. Shoots extremely well right out of the box. I put on a reflex sight and some pop up backup metal sights and it took less than 5 rounds to get it sighted in. Was shooting 3” groups at 50 yards with just ball ammo. Has a wonderful smooth trigger. Absolutely love this little gun. Very little recoil with the 9mm and very light. I was surprised at how accurate it was right out of the box. PSA makes EXCELLENT GUNS at affordable prices. I will be buying more fron them. Keep up the great work PSA.
