help finishing ar upper

[xtcjpr13]

So I am in the process of build an AR Pistol. It is my first build and the lower went together rather smoothly. The upper on the other hand is giving me some issues since I dont think I have all of the proper tools for the task. Is there anyone in the Poconos area that would be willing to lend a hand?

What issues are you having? Tools needed sre very minimal

well i dont have the blocks to put it in a vice so i am not sure that im getting everything properly tight. i also need a couple roll pins since i dont think i got one for the gas block and bent the one for the forward assist. My main issue though is that the compensator doesnt line up properly when it gets tight. im not sure what to do there either!

Need a vise block for the upper to get the barrel torque right. you need a crush washer to get the brake to line up.

You can also use a barrel extension torque tool, which puts less stress on the aluminum upper receiver. I've come to prefer those.

You clamp the barrel nut wrench in a bench vise, then bear down with this tool and a 1/2" drive wrench, and torque the barrel down with minimum stress on the upper.

I have the crush washer, and there is no way is going to line up right. ..
