The E-BCG's® forward porting and unique shape assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors. However, it should be noted that the E-BCG® is not a complete solution for this issue and all rifles are different. 'Over Gassed' guns will suffer to a larger extent from this problem. **SPECIFICATIONS** - Full Auto & Semi-Auto Compatible - Forward Porting, Enlarged Vents - Balanced flared boss - 8620 Carrier, Heat Treated, Hard Turned - 9310 Bolt, Hard Turned / Ground - NiB UCT EXO Coating - CP-R360-H Domed Cam Pin - Mil-Spec Gas Rings - Mil-Spec Staked Gas Key - Grade 8 Hardened Fasteners - All Hard Chrome surfaces are to MIL-STD-171 1.2.2.2 - Lifetime Warranty ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
