18.6" heavy vx 16" light barrel advice needed
I'm looking at buying a XCR to use primarily in 7.62x39. The pricing seems to make it attractive to buy a 5.56 XCR rifle and then 7.62x39 conversion. I will probably use the 5.56 only for target shooting (200-600 yrds) or shooting varmints. Given this use, which would you recommend - 18.6 or 16 inch barrel? Since RA only offers 1/9 twist, will the 18.6" barrel stabilize 75-77gr bullets better than the 16" barrel? I guess bottom line what I'm asking is will the 18.6" barrel provide meaningful improvements in velocity and accuracy over the 16"?
