We have re-filmed this with a true Colt 6921 recently using an actual USMC RCO (ACOG TA31) and will publish that instead as the M4A1 Block 1*** One of our GWOT classic U.S. Issued M4A1 clone with a Trijicon TA31 ACOG, stepping it out. (In hind sight we were pretty harsh on the M4’s performance. The rifle actually performed very well for a standard rifle with a mil-spec trigger.) This same configuration saw a lot of action world-wide with the U.S. Armed Forces in the last two decades. This rifle is still frequently seen in news images and videos. Shot with Fiocchi .223 55grain ball ammunition. Parameters: 2x shots per target from 150y to 500y, segmented per 50 yds. Shot with Fiocchi .223 55grain ball ammunition. Trijicon TA31 ACOG 4x32mm https://amzn.to/32hrB3U We have a discount for Slate Black Industries MLOK accessories! 👉 www (dot) slateblackindustries (dot) com Discount code: 9HOLE Consider supporting us via Patreon 👉 http://www.patreon.com/9HoleReviews (you an also access the Practical Accuracy Scoreboard here) Shopping on Amazon?
