    VLTOR A5 RE Buffer spring T&E

    The rifle is a DDM4 with an Azimuth BCG, JP gas-ring (1 piece), and carbine RE. The gas-port was pin gauged at between 0.0735" and 0.0745". There is roughly 5,000 rounds on this rifle, with about half of it on the Azimuth BCG. A Colt mil-spec ejector spring was used, and a SAW/Ken Elmore "Green" extractor spring with black mil-spec buffer and no O-ring was used. The suppressor depicted is a Surefire 556-212. Ammunition used was .223 Bronze 55gr for unsuppressed videos, and PMC XTAC M193 55gr 5.56 for suppressed videos. The same A5H2 buffer was used for all videos, as it is the OEM included buffer with the A5 system.

    Of significant note, the BCG and upper receiver remained MUCH cleaner during A5 testing than it did during my Carbine RE testing. 2-300% cleaner, by guesstimate.
