Product Description

What's in the Box

  • Omni Maxx P4 300 Blackout AR Pistol
  • (1) 30 Round Magazine
  • Owner's Manual

The Omni Hybrid Maxx P4 features ATI’s metal-reinforced polymer upper and lower receivers for reduced weight and increased 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 durability to withstand recoil and constant use. Bottom line: you get an AR Pistol with “heavy metal” strength…at a price that can’t be beaten.

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.

Firearm Features

  • Both the upper and lower are built from a fiberglass-composite polymer over a zinc metal insert, with extra reinforcements in high-pressure sections
  • 8.5″ barrel with 5/8×24 threads
  • Fully patented inter-lock hammer and trigger pin retainment system prevents movement during firing
  • 7″ M-LOK handguard
  • Plum Crazy lower parts kit
  • Standard charging handle
  • Trinity Force Breach 1.0 Pistol Brace
