    • Based off a Billet Aluminum design where all others are of a less superior Forged design, ours are reinforced in all areas of concern and the strongest available on the market bar none!


    • Has an internal pocket radius in the GEN 2 design toward the rear of trigger which eliminated the back strap from breaking


    • Has a Reinforced water line on our receiver, all others do not have this upgrades


    • They are impervious to gasoline, acid, acetone, kerosene, and will not break after being dunked in liquid nitrogen and thrown onto a concrete floor unlike aluminum which would shatter!


    • These can handle up to 500 degrees and in the summer time, they are not hot to touch like aluminum receivers!


    • They are lighter than aluminum and can be run over at the mag-well where aluminum will be crushed and rendered useless!


    • If you scratch ours they retain color and also a little WD-40 and some green scratch pad removes the scratch.


    • Our fire controls require no lubrication whatsoever


  • The castle nuts do not need to be torqued, or staked as they are factory torqued with blue loctite, and will not come loose
