CNC Aluminum Bolt Carrier

CNC machined (Aluminum). Intended to provide "crisper action" by lightening the total bolt weight. Its use was recommended during winter months when temps are cooler. (Propane loses much of its power when temps drop below 60 degrees fahrenheit.) A lighter bolt would be easier for the gas to propel backwards. The bolt didn't live up to its expectations and reports spread of them absolutely "nuking themselves" when used with the 500fps valve. This was another disappointment for WE owners who invested in this bolt. It was first downgraded to "350 fps use only" - then it was completely discontinued.
