For: Madbull SWS Licensed 7.25" Free Float RIS for M4/M16Product Information:
VERY nice Rail system. It is light weight but durable and looks amazing. It is almost identical to the Noveske RIS except it has 1 less QD sling port and different trades. Free float system is pretty cool. Though the barrel nut doesn't properly align with my KWA receiver when fully tightened. A spacer might fix this but i just slapped my red dot on the bridge area to prevent it from wiggling.
Aluminum light weight.
Doesn't align properly with a KWA KM4 RIS
