From the onset, Windham Weaponry has had one goal: to build the finest AR type rifles in the country. All of their rifles are built with 4150 chrome-moly vanadium steel barrels, which are chrome-lined for long wear and ease of maintenance, and 7075 T6 aircraft aluminum receivers with a durable black hard coat anodize finish. Their SRC is available in a modified version designed to be compliant with state regulations in Massachusetts and New Jersey. The SRC utilizes a gas-impingement system that's housed in an M4-A4 flattop upper receiver with a picatinny railed gas block. The SRC is free of sights and handles, leaving it open for optics and other accessories. The rifle's bolt is made of Carpenter 158 Steel and its 16" M4 profile barrel has an A2 flash suppressor and a 1 in 9" right-hand twist and a compliant welded muzzle brake. Other notable features include: a fixed position buttstock, 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.
