Product Description

A team of the finest firearms people in the U.S.A. has been re-assembled to bring to market the highest quality AR type rifle possible. These good Maine folks - all former employees of Bushmaster Firearms - offer many years of experience in the industry, and all look forward to working with you, to serving your needs, and to building you a great rifle. And, Windham Weaponry, Inc. will back up that promise of quality with a Transferable Lifetime Warranty on their rifles.

The Dissipator concept has been around for quite a few years and here is Windham Weaponry’s version of this “Old School” configuration. The Dissipator combines full length handguards for better heat dissipation and the same sight radius as a 20” target rifle on a carbine gas system. The gas block is concealed under the handguards and the 16” M4 profile barrel balances out this carbine at 7.2lbs.
