A new airsoft company called "Angry Gun" has just released their Super Recoil Kit for gas blowback (GBB) M4 rifles. We already did a test for this kit, and it did not disappoint us with its performance. The blowback feel of our M4 rifle has significantly increased and was enhanced by this thing. Basically a much heavier steel carrier that creates more momentum and recoil on every shoot. Check out the specs:
Solid stainless steel construction
Designed as an upgrade for your M4's original recoil kit
Truly enhances and increases the blowback (recoil) force
Comes with a small L wrench for assembly and adjustment
This particular kit is suitable for use with WA M4 Series. We found that it also fits the INOKATSU M4 perfectly well!
