• yes, that is a problem. I've found out that when the bolt travelling back close to the end and I can see the returning spring is tilting up and down a bit, and the top cover can't be closed easily, have to push it and force it to close. I didn't like it and it's not parallel with the bolt, that could create higher impact and get more wear on the bolt too. even when I shoot in auto, almost every 5 shots and having one to two weak shots, so strange. then I shim a small piece of paper and hold it in place(tilt down a bit), everything are working perfectly......spring rod parallel with the bolt and moving freely, cover is closed easily, full auto is so smooth now.

Not sure if its effecting the bolt travel much, as its only a very slight incline upwards, but I'm thinking of shimming it on one side as it can impact the release's return, and thus the cover locking ability until its moved into place again.
