6310RF and 6315RF are Plan B compatible flash suppressors / compensators, a collaboration between Revival Defense https://www.revivaldefense.com/ and Forward Controls Design. Based on the successful 6310 and 6315 designs that have been well proven on many of our Dead Air Keymo and Xeno devices, both are a closed bottom flash suppressor / muzzle rise compensator that provides 15 to 20% better compensator performance, without the extra muzzle flash, concussion and noise normally associated with a compensator. The shorter and smaller 3 o'clock and 9 o'clock ports force more gas to be vented through the 3 upward facing ports. 6310RF and 6315RF, like all 6310 and 6315 family Mfg: Forward Controls Design
