ATI Omni Multi-Caliber Complete Lower Receiver


    Many of you know we have covered the stripped ATI Omni receiver previously. The model I looked over today is the complete lower ready to mount an upper and head to the range.

    This Omni receiver is made to handle about any caliber upper you care to name.The user just needs to mount say a 6.8 caliber upper and it will function as well as a 5.56 upper. The main body is made of a polymer material with standard fire controls made of metal. Internals are mil spec parts. The buffer tube is metal with an included recoil spring. The stock is very similar to the military version. The trigger pull is a standard pull weight for most AR 15’s.

    The lower itself has been tested extensively for durability and reliable function and passed all of the factory test. The price will get most readers attention. While the stripped lower is about $50 this complete lower is priced at $134.00. That’s a great price for any complete lower.
