Hello everyone. First post. I recently bought a psa ar10 with the 20inch heavy barrel upper and bought the psa gen 2 lower and wow. I was a little Leary to do so after reading post from years back on problems but this baby shoots. I have the stainless barreled version with free floated mloc handguard. No malfunctions after 100 rounds and accurate to boot. I am a hand loader but have only put factory ammo through it so far. Here is a pic of groups with Australian outback ammo and federal 168 matchking that it likes. Groups were fired from a bag at 100 yds. Not excellent but I’m happy with the rig being mainly a bolt gun guy.
