    Product Description

    Steel - CAR Length Bolt Extension for STG Universal Heavy Bolt System U9SF, U45, & U762

    This is the heavier extension for lower rates. This is typically used with the 45 and 7.62 setup.  It can also be used with the 9mm setup but only with 'hot' ammo and/or suppressed setups with more blowback energy.
