With the Kentri short buffer system you make your AR rifle or pistol more compact, and still have the option to use a pistol stabilizing brace, without breaking the bank. 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). The tube is available in two profiles compatible with popular stabilizing braces: the SB Tactical (KTRSB) and Shockwave Blade (KTRSH). The Shockwave profile is shown in the photo with the units installed.
Compatible with pistol (9mm and 40S&W, BCG without pinned weight) and rifle calibers (up to, but not including 375 SOCOM). In rare cases, under gassed AR15 systems have a slightly increased instance of failure to feed. In every instance increasing gas pressure has led to a successful resolution. Use with blowback pistol calibers will experience a reduced duty cycle of the carrier spring versus direct impingement based on multiple factors including ammo and carrier mass. Replacement carrier springs will be made available.
