Not a regular h2 buffer. avoid for binary, frt or full auto - Dark Storm Industries DS-15 H2 Carbine Length Buffer 4.5 oz

I purchased this buffer thinking I would receive the standard H2 buffer which typically has two tungsten weights and one steel weight. With this buffer the actual carrier is made out of steel to increase the weight and then it has three standard steel weights inside of it. After installing this buffer I started experiencing bolt bounce and light primer strikes when trying to use a forced reset trigger. The problem immediately went away when I swapped back to my conventional H2 buffer. For semi-automatic it function just fine and had a very similar ejection pattern to an H2 buffer. If you're in the market please spend the extra $5 and get an actual H2 buffer that comes with the tungsten weights a posted this one where corners were cut to save a little money and not use the right materials. Avoid this entirely if your goal for purchasing a heavier buffer includes reducing both bounce as this one functions even worse than the standard buffer when it comes to that.
