ATI Omni Hybrid Maxx Semi-Automatic 5.56 NATO/.223 Remington Rifle
Incredibly tough. 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. You can deploy this dependable AR-15 in your collection for less than you think when you order here from Sportsman's Guide.
