love how RA has produced so many variations of the XCR-l but there is always one other thing that's missing. I suspect it'll ALWAYS be that way for some folks particularly on teh interwebs and among those not inclined to purchase.
the 1-7 barrel is available now but in limited quantity. I actually saw one on a new rifle a month ago with my own eyes.
funny thing about barrel twist is that in real life the 1-9 in the XCR stabilizes everything I've run thru it just fine. I think some folks are more interested in numbers than results and few will ever see any benefit to a 1-7 in the XCR, as the faster twist barrels seem to be un-needed until about 300 yards with only the heaviest of projectiles. I have a 1-8 twist and 1-9 and they are REALLY close in on target results and both stabilize the heavy bullets just fine.
