Cooper's mileage obviously varied, but the two RRA AR-15's I have had, they were much more finicky to feed than any of the bushmasters I've had. The 2 RRA models I had were the 20" Coyote Rifle and a CAR UTE2. I HATED the coyote rifle trigger, but I'm totally intolerant of creep. The UTE was a great 3 gun rifle, but I had a lot of feeding issues with it, and it cost me about 25% more than the Bushmaster Superlight carbine that replaced it as my 3gun standby (other than my Wilson Combat). I also didn't understand why the UTE came with a 2stage trigger? Maybe I got lucky with my bushmasters, but the accuracy and feeding has been 2nd to none.

Admittedly, the fit and finish was better in the RRA's than the Bushmasters, but I'd rather have an average looking wife that could cook than marry a supermodel that burns maccaroni and cheese. Then again, I'm pretty picky about feeding. Either a gun feeds what I want to feed it, or it gets sold.
