With the Pantheon Arms Kentri short buffer system you make your AR rifle or pistol more compact, and still have the option to use a Shockwave Blade pistol stabilizing brace.  Made from type III hardcoat anodized 7075 aluminum and stainless steel, the Kentri extends just 3.5 inches from your lower receiver, and uses a standard bolt carrier (not included). This system is compatible with standard AR-15 pistol and rifle calibers. 

The introductory price of $55 is valid until Nov. 27th, 2017.
