Re: Noveske?
I've owned a number of Noveske rifles over the last couple years, and have sold most of them for one reason or another. I realized that I didn't like all of the gadgetry, swithchblocks, VIS, m249 spec chrome lined barrel, etc as these items were expensive add-ons that didn't serve a purpose for me. So recently I ordered two new uppers, a 6.8 (my third 6.8 Noveske upper) and a 5.56 (fourth Noveske 5.56 upper) in the same configuration---the 16" Rogue Hunter, but with the 16" Recon barrel instead of the light profile barrel ($10 upgrade). Both uppers are built well, and are very light. The 5.56 is stored until I shoot out or sell my MSTN 17" upper (Noveske Barrel), but I've shot the 6.8 quite a bit and really like it. My experience with the Recon barrels is nothing but positive, with one of them shooting on average ~13/16" for over 60 5rd groups (using FGMM 69gr and Ultramax 68gr).
Nonetheless, sorry for the long post but I have nothing but good things to say about the Noveske uppers and rifles I've owned and used. I would think carefully though about what accessories you need and think simple and light, especially for a GP carbine.
