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 and rifle calibers. 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.
Installation instructions can be found, here.
