The Omega AR12 is a semi-automatic shotgun, featuring an adjustable gas system. You can flip flop without any tool for low brass and high brass. These shotguns have a 5,000 shot warranty from the manufacturer.
I bought this AR12 a few months ago.. It shoots well and Ive had no big performance issues, yet. It comes with a useless sling, and a useless owners manual. The swivel bracket for the sling they provide is in the wrong spot. I had to take the bracket off and drill a new hole closer to the upper receiver. Even still, the sling they provide doesnt work. Its a tactical sling, but its too long. The barrel drags on the ground. Had to buy a better sling. The owners manual is just a generic one for basic shotguns or something. I have no idea how to properly disassemble my shotgun for cleaning the way its suggested by the manufacturer. I have no idea how to adjust the buffer for different loads. The manual doesnt even mention that. So Im clueless on that part of it as well. Lastly, I've tried for 2 months to get ahold of the manufacturer with zero success. What good is a warranty if you cant even get ahold of the company. Its like you're on your own after you spend 700 bucks.
