NJK Custom Bolt carrier weight
Solid stainless construction designed to fit into the back of your bolt carrier. The extra weight will delay the opening of your bolt so there is less pressure on your brass when it is ejected. Especially useful for 16" carbine length gas systems that run at high pressure. Fits bolt carriers with an opening of .610" diameter or bigger. Some upper/Lowers will require both takedown pins open for installation. Adds 2.8 oz to your recoil system.
