American Tactical Omni Hybrid MAXX 5.56 NATO Black AR-15 Pistol

A: A firearm chambered for 5.56 will also shoot a .223. A firearm chambered for .223 should not use a 5.56 round. So you would be able to shoot .223 through this firearm as is it chambered for 5.56. Hope that helps!

A: To clarify: Too many people tell you "they're the same round" Not true. .223 will shoot from a weapon designated as 5.56. But not the other way around.

A: Mounting a "shoulder butt" requires a BAFT tax stamp ($200 or so) for the manufacturing of a short barrelled rifle. If you don't want to do that, then you may want to look at SIG's arm brace.

A: The cheaper one is a 5.56 chamber, the more expensive model has a wylde chamber that accepts .223 and 5.56. I would buy the cheaper one and not look back.

A: Jovahn, I sorry to hear this! I've never seen a price jump like that.

A: Jovahn, you may want to speak with a manager. It's been my experience that prices go up that high when inventory goes low. I'm almost certain the price will drop when stock level rises. I whole heartedly agree that a price cannot be honored from a mere 2hrs prior is ridiculous for a company the size of Buds..

A: Richard, barrel diameter under the gas block is .75"

A: Richard, the gas block is 0.75" hope this helps.
