Jonathon - this should go right on your ATI with no problems, if you have the base model with the slip-on type hand guards, like this: budsgunshop.com/catalog/product_info.php/products_id/41118/ati+gomx556p3+omni+hybrid+maxx+p3+semi-automatic+223+remington%2f556+nato+16+30 Its just a matter of removing the old ones and bolting on the new one.

Jonathan, yes Sir it will fit. Just follow this "How Too" video and you will have it replaced in 3 or 4 minutes (same procedure) : youtube.com/watch?v=8xrcCIokNz8

Yes it will fit and work just fine

Jonathon, This should fit and work well on the ATI omni max hybrid. Pull delta ring back. Place both halves in groove. Bring them together and fasten together. No problem. At 6.7" long fits great with he carbine length gas block.
