Thanks for your input AR180Shooter, learning from more experienced shooters like yourself is the greatest benefit to being a member here at Gunnutz. Now that I have a better understanding of the x39Rd. from your explanation I think I'll go back to my original plan of using the 7.62x51 calibre.
Now my dilemma will be to go the NR route with an "OKAY" rifle such as the XCR-M, RFB, FNAR... (well that's at least how I feel about those rifles when comparing them to a decent AR-10); or step over to the Dark Side and the way of a Restricted and all that implies with what I'm really itching for an AR-10. Right now with my budget I would be looking at either an Armalite in 7.62x51 with a SS 20" barrel or the DPMS Recon II .308 with a 16" SS barrel. Yet until I find a range report on the DPMS (Epoxy7 please report

) I'll be leaning towards the Armalite with what I believe will be accuracy that satisfies me. However the DPMS may be the smarter buy from a financial perspective (a few hundred dollars less while offering more features) and that shorter 16" barrel doesn't necessarily mean less performance from an accuracy standpoint even if you give up a little velocity. Add to that the more compact package of the DPMS which I prefer and it becomes a very difficult choice.
