Is it possible to modify ours a little bit?
My M4 also has a trouble: the small part in the nozzle was moving quite freely(noticed it yesterday) Okay I told myself just clean the barel(there where 4-5BB's struck in there) and simply glue that thing in place(glue become at its peack after ~24h) I just tried it back and there is just pressure enough to assure a part of the blow back action but too less to reload...Oh I forgot....When I removed the 4-5BB's from the barel, a steelstring came out too...Do I have to assume my Hop Up is also dead?(I'll order a new "power tune up kit" ASAP but
