Ive got two of those element nozzles, works like a dream! Only problem was that there was no any instructions how to assemble it (there`s more parts in element nozzle than agm)
Spend good two hours and finally got it right.
parts in my 061:
-Element nozzle in AGM bolt carrier
-PGC/Pro-Win Hop-up replica and 6.04 Cyma barrel (waiting for vanaras, cyma is too short, from ak74su)
-ACM bearing hammer
-Element reinforced spring-set
Everything else is stock.
Bolt catch didnt work even whit those 8bbs behind mainspring. Waiting for my 5ku mags...
ACM antirotat
