Having trouble with a build

[washguy]

We have established it is a rifle length correct?....if so enlarge the port...easy peasy...just put a dowel rod in the barrel to let you know when to stop if doing it by hand drill...if its a drill press no worries     Wash

[washguy]

Thumper      get you the drill bit number that is .093 #82 or even a #41.096  or a 3/32 bit which is.0938   Wash

Looks like I have it taken care of guys. I appreciate all the shared knowledge. I am new to the gas gun world and have learned quite a lot over the past couple weeks. Here is what I did. I took survivalshops and washguys advice and started looking at gas port sizes. Drilled mine to .093. Might not have needed it but purchased a JP Silent Capture Spring buffer and installed it. Went to the range and started adjusting my gas block with i round at a time. Before this it had never locked the BCG back when empty. About 5 shots at a half turn adjustment each time, it locked back. Big Smile. Loaded 2 rounds in the mag. It didn't pick up the next round. 1/4 turns at this point, 3 shots later, it fired 2 rounds. Another Big Smile. 1/2 turn more and locked it down. I loaded 10 rounds in a magazine and the fifth one misfired. Looked at the primer and it barely had a firing pin mark, but it was there. Cycled another round and shot 3 more times and the same thing happened. Odd. I pulled the upper and lower apart and looked at the JP pc. It was a little ways back from the buffer spring retainer pin, shook it and it was loose. Pulled it out and put 2 quarters behind it and fired 4 magazines with no misfires or mishaps. Came home and cut a pc of the nylon bushing they send with it .125 and dropped it in, put it all back together and Guys...I think I'm done. Now to start working up loads.  Thanks again guys for all the shared knowledge. If anybody ever needs AC advice, hit me up.

Thumper.  Way to go!  Your rifle will only get better when it broken in...you done good!    I dunno whats up with these barrel guys..you would think they would have the port size down?  Well good for you!       After its broken in and you get a load worked up...come back and we will reduce the recoil. .    Wash
