ATI Omni Hybrid Maxx Features The ATI Omni Hybrid Maxx is built around a 16 stainless steel barrel chambered in 5.56 NATO/.223 Rem with a 1-in-8 rate of twist for consistent accuracy across a range of factory loads. The Omni Hybrid lower features a patented hammer and trigger pin retainment system preventing movement from the hammer and trigger pins during firing for more consistent function over time. ATI's patented over-molded metal insert reinforces the buffer tube housing and rear takedown pin allowing for metal-on-metal contact at both points to increase strength and durability against recoil and repeated firing. For range shooters and budget-conscious buyers who want a durable AR-15 that holds up to regular use the Omni Hybrid's reinforced lower delivers. The 15 M-LOK handguard includes QD sling attachment points and gives shooters room to mount lights optics and other accessories along its length. The fully-patented metal-reinforced polymer receiver set keeps the rifle lightweight and versatile while maintaining the durability shooters expect from an AR-platform rifle. This model ships complete with a 60-round magazine giving shooters substantial capacity right out of the box. For range shooters and home defense users who want a lightweight accurate AR-15 without breaking the bank the Omni Hybrid Maxx's handguard and included magazine deliver.
