The Latest PRi GenIII AR15/M16 Freefloat Forearm System and barrel nut are constructed of light weight high strength carbon fiber aluminum and high strength steel for the best possible combination of weight and strength. The carbon fiber also reduces the amount of heat transferred to the shooter’s hand during rapid or high volume firing. The long top rail matches the height of the top rail on the standard flattop receiver.
This version includes the 8.5″ rail mounted at the 6:00 position. A $35 value!
