I got my PSA 9mm ar back from PSA and all is well,so between rains I took it to the 25 meter pistol range just for a thorough ringing out, so 350 rounds through different magazines ,the ammo a mix of federal brass federal aluminum case and wolf and silver bear steel case and some speer hollow points without a hicupp ! Before I moved to 50 and 100 it started raining again and the battery on my red dot died , it’s okay it was an old battery in an old sight. So far Ive been very impressed
