Hello Jensen Arms.
Don't know all the number codes (6XXX) for Colt AR's. I am looking for an A3, full length HBAR, 1/9 twist Match Target type AR-15. I have this in preban config and it is called a Match Target (might be a 1/7 barrel, cannot remember).
Do you have anything like that in the latest (LEO?) versions or whatever Colt is shipping these days?
