I wasn't as concerned with barrel profiles or cold hammer forging as barrel length for velocity and barrel quality for accuracy.
The close range carbines 10.5" 14.5" and 16" with Red Dot Sights have; NATO chambers, chrome lined barrels, and single stage triggers, whereas the 16" Recce and the 18" SPR have tweaked chambers, stainless match barrels, and 2 stage triggers.
