Barrett’s REC7 piston-operated AR-15 rifle was previously only available in 6.8mm SPC. It is now also available in 5.56mm NATO. They have also made some minor improvement to the rifle. They are now using a Magpul MOE stock, instead of a standard M4-style stock, and a Daniel Defense free-float rail system.
I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
