From the onset, Windham Weaponry has had one goal: to build the finest AR type rifles in the country. The SRC-CF-THD utilizes a gas-impingement system that's housed in an M4-A4 flattop upper receiver with a picatinny railed gas block. The SRC-CF-THD is free of sights and handles, leaving it open for optics and other accessories. The rifle's upper and lower receiver are made of molded carbon fiber composite and its unique Thordsen stock makes it compliant for New York. The bolt is made of Carpenter 158 steel and its 16" chrome-lined M4 profile barrel has a crowned muzzle and a 1 in 9" right-hand twist. Other notable features include: M4 double heat shield handguards and an A2 black plastic grip. Each rifle ships with a hard plastic carrying case, a web sling, and one 10-round magazine and carries a lifetime warranty.
