I ordered my new AR today for USPSA rifle and 3 gun from Cabelas in Rogers MN. The gun library there had a brand new (never fired anyway) Sabre Defence XR15 Competition Extreme. It has 45 degree offset irons, an 18 inch barrel with rifle length gas system, and a gill brake. List price on the gun was alot more than I wanted to spend, Cabelas had this one for $1700, and I got it for right under $1400 (employee discount). Now I'm thinking of ordering a Trijicon Accupoint 1-4x24 w/ green illuminated triangle reticle. i can pick one up for under $500. Opinions on the rifle? The optic?
