From the manufacturer

For anyone using .308/7.62 AR-type rifles, it is common knowledge that many factory rounds exhibit excessive primer flow and/or ejector smear. At its core, this is a result of ammo development being done by manufacturers only for manual platforms without testing in semi-auto platforms. Some rifle manuals even record the maximum recommended load data beyond the functional range of these rifles. Unfortunately, these issues will persist until the manufacturers of ammunition realize that an AR platform requires a unique pressure curve to allow for both accuracy and reliability. Manufactured to the exacting standards of our standard bolt offerings, the High Pressure EnhancedBolt(TM) des Mfg: J P Enterprises SPECS: SAE 9310 nickel-chromium-molybdenum steel, chromium nitride. Fully assembled with extractor, gas rings, ejector, pins, and springs installed. .308 fits DPMS/AR-10 Style rifles.
