Based on good reviews and a really cheap price. I recently bought a used TriStar Arms shotgun that had a broken trigger guard. I called the company to order a new one and they said that it would be about twenty bucks for a new one. They also said that they would put it on for free and check out the shotgun for me. They said they like their products to be in top shape.
I sent it in. They got it on a Wednesday. I got a call that morning from them but missed it and they left a message. by the time I could call them back that afternoon, they had replaced the entire trigger group, replaced an "O" ring, test fired it and already had it on it's way back to me. NO CHARGE Top that Bennelli! It shoots great too. That is, it shot great, before it was lost in an unfortunate boating accident. Anyway that kind of service is noteworthy. Click here for a great value.

For about $350 Bucks TriStar's Cobra Force Pump. It comes with Picatinny rails atop the receiver and on the underside of the fore-end. It has a stock, you just can't see it in this picture.
