Here's my AR pistol.
It's a cheap ATI Omni Hybrid 7.5 inch 5.56mm. Receivers are polymer. Trigger group is composite. It was very inexpensive. The stock trigger is very light and very smooth despite the low price. It's a definite upgrade over milspec. So far the thing has been completely reliable. It's accurate and fun to shoot. Loud, yes, but it's not uncomfortably so as long as you wear good hearing protection. I use 32DB rated foam plugs, and they're just fine with the pistol.
It does look a little different now. I changed out the brace to an SBA3, and the pistol grip to a Magpul overmolded grip.
