Hi!, do you know in some way how to fix well the hop-up chamberl to the outer barrel? the hop up chamber and the outer barrel are fixed by a little tiny screw and it get loose somtimes and the hop chamber wobbles, ruining my accuracy. Please don't said thread lock the screw

Btw it's a m28 rifle

Well.... Threadlocker would be the ideal solution to the problem as that is what it was designed to do... 222MS (purple) or 242 (blue) would work for that. Purple would likely be ideal for that as its made for small screws and its low strength.

Conversely you could put some teflon tape on the screw.

You could also drill and tap some holes into your hopup and externally secure it with more bolts. Shimming with tape also works.

Thanks for you reply, i don't want it the threadlocker because is not complete the upgrading of the chamber, so i will dissasembly again the all thing

I would try wrapping the front portion of the chamber with the teflon tape as well (keep it clear of the arm(s) obviously). I had the same issue with my M24 before and just two wraps makes it nice and snug, so even when that screw decides to back out it holds true.

that seems more feasible for now, it seems that our rifles have their own personality and will, they never work as one would like
