Since I started using a clip-on thermal I decided to get a monolithic upper. Got it finished this morning and then headed to the range. It is a Mega Arms MTS, 13" AR Performance 6.8 SOCOM(had it cut down from a 16"), Superbolt and NIB carrier. I am using hand loaded 95r TTSX. It took only 4 rounds to get it zero'd at 50 yards. The picture is the next 5 rounds at that distance. Measured .375". Gotta love them ARP's!!
