AR-15 rifles are the “Reliability-Enhanced Carbine” of the 21st century. The Barrett REC7
utilizes the fewest number of parts in any AR style rifle with a piston system dividing heat and powder residue from the bolt and trigger assembly. The result is a cooler, cleaner operating system. The piston can be removed without removing the top hand guard, making maintenance a breeze and routine maintenance does not affect the optical system. Barrett REC7
rifles are available in both 5.56 NATO and 6.8 SPC.
