10.3" NATO barrel w/ .070" gas port

For years if you wanted a 10.3" barrel for a faithful MK18 clone you had to buy a barrel, send it off, have it cut down and get the gas port modified, and then hope the work was done right. Alternatively you could pay a lot of money for an original Colt. Andro Corp made life way easier by offering a very high quality barrel from the factory that meets the specs to a T. The machining and finish are excellent, the rifling looks flawless, and the extension fit into the receiver is very snug. Very pleased so far with mine.
