MRA has AR-15 short barrels with carbine length gas systems, and non-restricted barrels with rifle length gas systems available for backorder. It may cut into the Renegade sales, but there will be a market demand for barrels for the WX-MCR kits with carbine length gas ports on non-restricted barrel lengths. Will you be adding that as an option to your web site, or can people contact MRA directly to order a non-restricted barrel cut with a carbine length gas port?
