We've decided on barrel profiles for the new batch! Both the 20" and 18" barrels will have an SPR profile. The 18" barrel will have a mid-length gas port, while the 20" barrel will be able to accept a gas port at both the intermediate as well as the rifle positions, depending on buyer preference. We will supply the gas tubes for all of these gas-port locations.
