Re: m4 hops

changing the hop unit will not change the fps too much, the seal between the bucking and barrel is more important, the firefly bucking is extremely good however is very costly at roughly £20 or so compared to a fiver for a tm or any other make one. personally i would rate the firefly bucking a good 9.5/10 and a tm one in comparison a 8.5/10, the extra price is not a very good spend of money but then you are getting the best bucking around!
