What makes these lower receivers different and better

• Since the creation of the GEN 2 fire control, we have not had one hammer come back broken, and they have seen from reports back up to 50,000 - 70,000 documented rounds!
• Based on 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 summertime, 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.

Personal Note - As an old school traditionalist, I have an aversion to anything that is basically all polymer.  Especially a hammer that strikes a pin over and over, but we have clients who have shot literally thousands of rounds through these. 

*Note E3 Arms Lowers are designed to function with all rifle length platforms. However, these lowers will not work correctly and should not be used in a pistol configuration.
