The UTM MMR conversions offer a live round lockout and consistent controlled velocity (a result of our patented dual primer system and driving bands).  We offer the most reliable Man Marking Round available on the market with not shavings in the barrel, no dislodged domes and superior marking.  UTM maintains accuracy without making our rounds faster – the UTM Man Marking Round is “bullseye” accurate up to 20 yards and “combat” accurate to 40 yards.
