AR-15 Build Kit (Upper, Lower & M-LOK Forend Set)

Build your next rifle with a precision-matched combo engineered for reliability and performance. This kit brings together three premium Windham Weaponry components:

• 7075-T6 Upper Receiver (Stripped or Assembled)
CNC-machined from aircraft-grade 7075-T6 aluminum and finished with hard-coat black anodizing for a durable, non-reflective surface. Comes stripped or fully assembled with an ejection port cover and forward assist. Features an integral MIL-STD-1913 Picatinny top rail compatible with optics, rear sights, or an A4 carry handle.

• Stripped Lower Receiver
A high-quality lower receiver supplied stripped, with the trigger guard already installed—ready for your preferred internal components and build setup.

• M-LOK Picatinny Railed Forend
Windham’s premium M-LOK forend, CNC-machined from American-made 6063 aluminum and hard-coat anodized to MIL-SPEC 8625. The top rail is T-marked and perfectly aligns with the upper (“same-plane” height). M-LOK slots are positioned at 1:30, 3:00, 4:30, 6:00, 7:30, 9:00, and 11:30 for maximum accessory flexibility. Includes integrated QD sling swivel pockets (3:00 & 9:00), a QPQ-treated barrel nut, and all mounting hardware. Laser-engraved WW branding completes the design. Made in the USA.
