I opted for A-2 grip and standard AR-15 trigger guard instead of Magpul grip and trigger guard. Both have QD sling swivels with Blackhawk two point slings. Seventeen round E-Lander in the magwell of PSA.

I think this is just another example of you get what you pay for when you gamble on cheap barrels. Maybe 75% are good shooters, but 20% are mediocre and 5% may just be unshootable. This is definitely a mediocre barrel.

I would be willing to bet if you redid the muzzle device with a accuwasher and lil to no tourqe, lapped the recover face,bedded the barrel, gas tube, gas block and reset the barrel nut tourqe too 35 inch pounds, it would shot much better groups.

I'm not wasting anymore time on that upper until after the season. Now I'm gonna have to take time off work in the middle of the day to confirm the zero on my ten pound 20 inch rifle... which I now get to lug around instead of the 12 incher all season. Guess better than borrowing a rifle.

I didn't buy the PSA upper kit because I wanted to spend hours stripping it down and building it back up correctly if they made a mistake. IMO any off the shelf AR upper should hold 2 moa with decent ammo, and that's all I was expecting this one to do. Either the barrel is crappy or the assembly is crappy, either of which is on PSA. I would consider sending it back, but it was on clearance and I dont know what their policy is on clearance items. They would probably warranty it but at this point I would rather not sit and play the waiting game for months and waste ammo testing it out to see if it's fixed yet or not.

I'm just gonna strip it down and rebuild it over Christmas, and it will shoot however it ends up shooting. If it has to remain a close ranger steel case pinker, so be it. With an AR15 I would rather deal with accuracy issues than reliability issues, I can adjust my range according to the accuracy.

meatsweats Wrote:Basically would take under 30 minutes to take off the flash hider and handguard (2 bolts) check gas block and check barrel torque specs. If even 1/2 hour. Hell I’d be willing to do it for you! My bet is that the barrel nut is over torqued. Regardless of the money spent you owe it to the gun to check it out.
