It weighs in at 4.3oz. (Depending on the density and size of the HDTP, the weight can vary slightly.)

So you're probably wondering what's inside to make this thing so great and different
Each buffer is filled with HDTP "High Density Tungsten Powder" so there is No reciprocating weights inside to make a lot of noise. It also makes for a Very Smooth cycling rifle. It eliminates the chance of bolt bounce and muzzle rise in full-auto. It also cuts down on Felt Recoil. It's a HUGE upgrade from a Standard Carbine buffer! It's designed for .223/5.56 but it works in all Calibers!
After it's filled with HDTP it's topped off with a mil spec bumper!
