    M4 upper

    Posted by David Robinson on Jan 6th 2021

    I couldn’t be more happy with this upper. I’ve ran cheap 223 and hot 5.56 in the same mag through it and never a problem. Off the bench it shoots quarter size groups at 100 yards if I do my part.

    No caliber marking found on barrel

    Not sure if upper is both 556 and 233 as there are no caliber markings on barrel. Need conformation before firing 556. Customer rep claimed it was both calibers Wylde but without markings I need conformation before use. Otherwise upper looks great in all respects.

    Top of the line item! Using a PSA M4A1 marked lower, built a very close clone of Military M4! Happy camper!
