JT excelerator 3.0, smart parts all american 2002 2 piece barrel, revolution hopper, aci 4 stage expansion chamber, 32 degrees electronic grip frame, bandit bolt, cp drop forward
it eliminates snow, no more white smoke out of ur barrel, alot more consistent!!
well if u need an asa adaptor itll look kinda wierd
its a great expansion chamber if u wanna switch from a stock one or a gas thru grip. its great and i love it. i got the 4 stage cause the 6 stage would of looked too big on my gun. but the 4 stage is doing awesome. if ur gun can take it get the 6 stage but if u want a more compact look get the 4 stage!
its a great product and i would recomend it to anyone who asked! its worth the money!
