The Windham Weaponry HBC is a semi-automatic carbine chambered in .223
Rem. or 5.56 NATO. Long story short, Windham Weaponry used to be
Bushmaster Arms. The owner of Bushmaster sold the company to Remington
and then in early 2011, he bought it back and renamed it Windham
Weaponry. The HBC is one of three AR-15-style rifles Windham produces. The HBC is identical to the standard model (the MPC) except for its heavy barrel that adds almost a full pound to its overall weight.
The HBC uses a gas impingement operating system, meaning the propellant
gases that push the projectile out of the bore are captured in a tube
near the muzzle. The tube directs the gas backwards toward the bolt and
ultimately push the bolt back and cycling the action.
Features include 6 position telescoping buttstock, which allows shooters
to adjust the stock to his or her liking, and the receiver is made of
7075 T6 aircraft aluminum, which is a corrosion resistant alloy. The
material was originally designed by the Japanese in the 1940s for
fighter jet frames. Now it’s commonly used to make bikes, planes, boats,
cars and firearms.
