    If I get a STAG 20" HBAR heavy barrel kit do I need to get an A3 upper receiver with an m4 feed ramp or not?

    I can't find any info on this on the STAG sight. Any help would be appreciated. Thanks in advance.

    More than likely, the barrel extension is cut for the M4 ramps. I'd suggest calling or emailing Stag directly to double check.
