Hard Cast
The heavyweight alternative to tungsten.
Buffer Weights
With basic H1 carbine buffers approaching $40 due to the the cost of tungsten, we had to start thinking outside of the box. Hard cast lead is 50% heavier than steel, and having dug hard cast bullets out of a dirt berm that looked like they could be re-loaded and shot again, I can attest hard cast is more than up to the task. With 90/6/4 alloy (water quenched) at ~20 BHN, over twice that of lead shot.
Bolt Weights
Those of us who can, do love to have fun with those forced reset triggers/safeties. When installed in a blowback pistol caliber AR, these systems demand removal/modification of the bolt weight. Since a blowback PCC requires a certain amount of weight to reliably function, removal may not be an option and not everyone has the means to modify one. Enter the hard cast PCC bolt weight.
