I bought a RRA Predator with the 20" barrel the day after Sandy Hook, and that thing has been a great rifle. Super accurate, feeds perfectly every time, and it looks good.
My Daniel Defense V7. I love it. Only thing I've really done is add a Hiperfire 24C trigger. She'll shoot a five shot half MOA at a hundo with handloads. Can't ask for much better. Id like to get a dedicated SPR one day. But this carbine is awesome. I got rid of that Vortex scope. It was a POS. Shooting pdogs in the sun even with a sun shade the glare was terrible. Go to my Leupold VX3 on my 22-250 and it was a helluva clearer. Go figure...
