Rocket Airsoft M4 Plastic Hopup Chamber Set

Rocket Airsoft M4 / M16 Hopup Chamber. Plastic. Comes with all the internal parts needed to operate and bucking. (please note: packaging may be generic or labeled as 'Rocket Airsoft', but is made by SHS OEM).  

This is a complete hopup assembly kit to replace your factory's.  Plastic units are good, have some give, and in some cases, are superior to metal chambers.  The SHS M4 AEG airsoft chamber is a good replacement kit for all guns.  Similar in design to the Krytac rotary (not a copy or replacement).
