ATI AR-15 Omni Hybrid Stripped Lower Receiver - Multi Caliber Accepts all standard AR-15 barrels and lower parts.

As a home builder myself I love these lowers, they are tough as nails, scratch resistant, user friendly, and best of all you don't have to worry about finishing the receiver to match your rifle. Drop in design and all standard AR-15 lower parts not only fit but in many cases work far better with this receiver than others due to ATI's Patented Inter-lock hammer and trigger pin retainment system which stabilizes and prevents movement from the hammer and trigger pins during firing.

The Omni Hybrid Multi-Cal AR-15 lower receiver is the perfect combination of strength and durability. Tested and rated to be as strong as a billet receiver, the new design provides extra strength in the high pressure sections and is designed to surpass the military pressure and weight bearing testing.

Primarily used for building .223/5.56 rifles but receiver is marked as Multi Caliber so ideal for use for 7.62x39, .300 B/O ... etc. builds.

Some folks have an aversion to these receivers due to the polymer coating.My opinion is exactly the opposite. If you look closely at our image you can see the steel frame in the forward threaded portion of the receiver. It truly has the strength of a Billet Lower, with the toughness and corrosion resistance of the best polymer blend available.

Each receiver carries A.T.I.'s Limited Lifetime Warranty. If nothing else, get a few of these and set them back, in this climate they are not only a great deal, but a great investment. 

Watch The Drop Test Video Here!
In this test they took an American Tactical OMNI HYBRID lower and paired it with a 5.56 upper receiver, and performed a drop test, similar to the test H.P. White Laboratory performs to test the safety and functionality of firearms.

To perform this test, they dropped the firearm from 48" on all sides, and checked to see if it still functions and remains undamaged, but more importantly does not fire on impact.  The result Success! No cracks, no misfires!

In this test they took an American Tactical OMNI HYBRID lower and put it to the ultimate test... run it over with a 8,000 lb. forklift tow motor! This test isn't intended as a real world simulation, rather to prove the strength of the zinc alloy metal insert that is contained inside of this reinforced polymer lower. Weighing in at only 1/2 a pound, this 8 ounce OMNI HYBRID lower receiver is lighter than most aluminum lowers, yet has the strength or more of a steel body lower!

The result Success! The metal threaded insert was not distorted or broken in any way, and the reinforced polymer survived, and is fully functional! Needless to say, this tough OMNI HYBRID held up to a test we all thought was impossible!
