Getting closer to purchasing an AR10. All the semi battle rifles I've owned (just about every platform in 308, sans the SCAR) I've never owned a AR, but have always been intreaged by the piston POF. Now that they're showing up in stock again I'm getting down to the nitty-gritty. I'd really like the revolution, but in my frugality (and more weight reduction) I may settle for a DI Rogue, but a little concerned I will probably want to upgrade to the adjustable gas system and the trigger. That starts to mitigate cost saving. I was planning on the pistol, but I have to admit I was really disappointed with the velocity drop in my 10" Draco compared to my 20" SKS. Maybe 308 would do better?? From what I've read the 12" POF & the SA Saint Victor still maintained velocities around 2100fps. My primary use would be for +/- 100yd hunting. Would someone care to opine & share advise? I'm also intreaged by the new 6mm ARK, but have never really embraced odd (non-military) calibers, just because surplus fodder is more affordable for practice.
