    Grant, thanks for narrowing the list down to 1. Very informative thread.

    ok noob question - I had always thought that 4150 is milspec. So whats the diff between a milspec 4150 and vanilla 4150? So basically guys like CD do not really offer milspec barrel then?

    You are welcome.

    MANY manufacturers use 4150 with the SOLE purpose in trying to make you the consumer believe that they are getting the best barrel steel available. If the steel does not follow this spec: MIL-B-11595E it is not the same grade/quality.

    I believe CD said their barrels are MPI but not HPT, which is somewhat useless IMHO.

    Do they sell barrels alone? I didn't think they were planning on doing that.

    They most likely do not follow the MIL-B-11595E standard. They are also most likely not HPT or MP'd as Shaw does not do that at their facility.

    I am pretty sure you can get barrels like what you are looking for in various lenghts at Specialized Armament, but you are going to pay a premium for them.
