The WC-15F receiver is clearly marked and paired with a flat-top upper that carries a full-length 1913 Picatinny rail, an ejection port door, and a forward assist. Wilson Combat branding is carried through the build with a marked muzzle device, logoed bolt carrier, and grip.
The 16 in stainless steel barrel uses a 1:8 RH twist to stabilize a wide range of 6.5 Grendel loads. The barrel is threaded and fitted with the Wilson Combat-marked muzzle device. No iron sights are installed.
Its Wilson Combat free-float M-LOK handguard is aluminum and features a continuous top rail for uninterrupted accessory placement. The direct impingement, semi-automatic action keeps the package light and familiar for AR-15 users.
Furniture includes a collapsible polymer stock with a 13.5 in length of pull, and the rifle uses a manual safety selector. The matte black finish ties the build together, and capacity is 10+1. Made in the USA.
