    Govt Profile vs M4

    The BCM 14.5 Mid Length uppers come with a Govt Profile barrel. How do these differ in weight and balance to the M4?

    The M4 barrel is a government profile barrel. It just has the additional cut-out forward of the front sight base to accommodate the M203.



    The original "government profile" barrel.



    M4 barrel




    BCM 14.5" midlength

    So weight wise they are going to be real close?

    I do not understand why companies try to sell barrels with the M203 cut to civilians. It seems to increase the risk of inaccuracy (residual stresses, warping due to heat) without providing any benefit.

    Because civilians continue to buy them. Once upon a time, I wanted an M4 profile barrel because they were uncommon and they were covered by the Rule of Cool. Now, I'd rather have something like Noveske's Afghan barrel because they aren't as common and are covered by the Rule of Cool

    Its just marketing appeal, and for a while the only 14.5" carbines with good barrels were coming in M4 profile. Even BCM's only 14.5" carbine length guns are still M4, and they only recently introduced the 14.5" middy.


    Noveske is only one of a couple who are making hammer forged 14.5" carbine guns.

    Are there any companies (Besides Noveske, and LWRCi) who's barrels are the same width through the whole thing? (Not government profile, or M203 cuts, etc.)

    They're heavier for sure, but I like them a lot more. Especially in SBRs.

    This is off topic, you'll get more visibility if you start your own post on the subject.

    Incorrect. The Noveske N4 light barrels weigh the same as an M4 government profile barrel of the same length.
