I have the RRA Coyote Carbine, 18" PP, 18" ATH, 16" Varmint and 24" Varmint, as well as 2 other LAR-15's. All are very accurate, all shoot better than RRA's accuracy guarantee. If I could only keep one, it would be the Coyote Carbine. I have shot literally thousands of FMJ's in tactical classes, both as a student and instructor, as well as killing several coyotes (often running), crows, PD's etc. with it. It has great balance, is light weight, has a superb trigger and with the six position Operator lower, is a favorite of my 9 and 11 yr. old grandsons. It has carried a Leupold VX-II 3x9x40 since I got it and I have never had to change anything since I Locktited it on. It shoots the PMC & Federal 55gr.FMJ's to the same POA as Hornady 55gr.PSP's (at least to 300 yds.) It will be one of the last rifles I ever part with. That said,and as previously mentioned, you can't go wrong with any of them. Second choice would be the PP, since it has a more hand friendly forearm than the ATH (at least w/o rail fillers). Good luck!
