Description

Rosco Manufacturing has made a proprietary patrol length gas system to make the dynamics work the best for you on and off the range. This system features an optimized gas port that will function properly when suppressed or unsuppressed. If you are an avid marksman and use your weapon frequently, the K9 continuous taper helps dissipate heat for the best performance possible. If you want to attach new accessories to your rifle but worry about being unbalanced, you do not need to fear that issue with this product. Rosco Manufacturing has shifted the weight to the back of the weapon so that the weight of accessories will balance out.
