The JP Enterprises tungsten weight is used to tune AR-15, M16 and AR-308 rifles. Tungsten is dense, so it adds mass in a small space for adjusting how the action cycles. It works with both .223 and .308 AR platforms. Compare it with your existing part or the manufacturer's parts diagram to confirm it matches your firearm before ordering.
