Built on the SRC (Sight-Ready Carbine) configuration, this WW-15 uses a flat-top Picatinny upper and an exposed railed gas block with no sights installed, allowing the end user to choose their preferred sighting system. It accepts detachable STANAG AR-15 magazines and ships with a 30-round aluminum USGI-pattern mag.
The 16" barrel is made from 4150 CMV (11595E) steel, chrome-lined for durability and ease of maintenance, and machined to the M4 profile. It is threaded and fitted with an A2 flash suppressor. A 1:9 RH twist provides broad compatibility with common 5.56 NATO and .223 Rem bullet weights. The carbine-length gas system and direct impingement action follow proven AR-15 standards.
Forged 7075-T6 aluminum receivers wear a hardcoat anodized finish and include a shell deflector, forward assist, and dust cover. Internals include a Carpenter 158 steel bolt, matching Windham's focus on established materials and specs.
Furniture consists of a two-piece carbine-length polymer handguard, an A2-style pistol grip, and a 6-position collapsible M4-style stock. The rifle weighs approximately 6.3 lb and measures about 32.375" collapsed and 36.125" extended, with an adjustable length of pull of roughly 10–14". Made in the United States.
