New Polymer AR15 Lower Receiver from ATI

American Tactical Imports (ATI) has introduced its new ATI Omni Lower Receiver, a multi-caliber AR15 lower made of reinforced polymer. Since it was designed to milspec dimensions, ATI claims the Omni polymer lower is compatible with most current AR15 lower parts kits, grips and stocks. ATI says the durable polymer material “can withstand harsh environments as well as everyday wear and tear.” The Omni lower will be available as either a stripped lower, OR a complete finished kit including all lower internal parts and collapsible stock. ATI claims the Omni lower has tested reliably with .22 LR, 5.56×45 (.223 Rem), and .410 but is “not recommended for larger calibers“.

The Omni stripped lower has an MSRP of just $49.95 while the complete finished kit has an MSRP of $129.95. The Omni lower comes in either black or dark earth colors. The .22LR version is available now. The .223 (5.56) version is slated for release in August, 2012, and a .410 version will be offered in the fall.

Editor’s NOTE: This story is based on a press release by ATI. We have not examined or tested the product. Accordingly we can give no opinions as to fit/function, durability or safety. Likewise, we cannot venture an opinion as to whether the ATI Polymer lower would be legal in restrictive jurisdictions such as California. Nonetheless, this is an interesting technology that may prove useful in some applications. For example, the inexpensive ATI lower could work well with the Crosman MAR177 AR15 Airgun Upper, keeping total system cost down.
