ATI® Omni-Hybrid Maxx P3 5.56 NATO/.223 Remington AR-15 Rifle
The Omni-Hybrid Maxx features ATI's metal-reinforced polymer upper and lower receivers…which help to reduce weight and increase maneuverability without sacrificing durability! The lower receiver features an over-molded metal insert, which reinforces the buffer tube housing and rear takedown pin. This allows for metal-on-metal contact with both the buffer tube as well as the rear takedown pin, delivering the strength and durability to withstand recoil and constant use.
In fact, the Omni-Hybrid lower has been specifically tested to withstand all sorts of use and abuse. The folks at ATI put it through all the pressure and weight-bearing tests, similar to the US Military's testing, and found it to function flawlessly, even after supporting up to 250 lbs. and being run over by an 800-lb. forklift. Then, they ran 2,000 rounds through it without a hiccup.
