I was looking at a 509mm Prometheus 6.03 tight bore barrel and a Prometheus Neo Strike Hop Chamber, but i'm stuck on the type of bucking/rubber the most voted ones i have seen are for systema bucking and an SCS nub OR firefly bucking with their nub. Any experiences with the above setup? or the above rubbers? Cheers.
P.S. i know the barrel is longer than a stock m4
but i'll have a silencer to compensate.
