Davidson Defense Vanyar (Suppressor Ready) 16.5-Inch AR-15 5.56 NATO Rifle Upper Build Kit
The Vanyar Upper Build Kit is built around a 16.5-inch "Satellite" 5.56 NATO barrel machined from 4150 chrome moly vanadium steel in a medium profile, with a mid-length gas system and a Nitride finish. It is paired with a 7075-T6 aluminum upper receiver with M4 feed ramps and a black M-LOK handguard. The medium profile balances weight and stiffness at the front of the rifle, and the 1:7 twist suits a wide range of bullet weights in 5.56 NATO. The 1/2x28 muzzle threads accept a compatible muzzle device, and this build is listed as suppressor ready. A muzzle device is not listed with this kit. BCG and charging handle are not included.

Barrel and Gas System
The 16.5-inch "Satellite" barrel is machined from 4150 chrome moly vanadium steel in a medium profile and finished in Nitride, a surface treatment that adds hardness and corrosion resistance while leaving a clean, matte black look. Its 1:7 twist rate is suited to a wide range of bullet weights in 5.56 NATO. The barrel runs a mid-length gas system through a micro low-profile gas block sized for a .750-inch gas journal, and the low-profile block helps it sit cleanly beneath the handguard. The muzzle is threaded 1/2x28 for a compatible muzzle device or suppressor mount.
Upper Receiver and Handguard
The upper receiver is machined from 7075-T6 aluminum with M4 feed ramps and an anodized finish, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a black M-LOK handguard, and the M-LOK slots give the builder room to mount lights, grips, handstops, and other accessories wherever the setup calls for them.
Compatibility
This kit is built for AR-15 lower receivers chambered in 5.56 NATO. Handguard length, material, and free-float configuration, gas tube details, ejection port door and forward assist configuration, and muzzle device inclusion were not supplied with this listing and should be confirmed before purchase. Because the BCG and charging handle are not included, they must be sourced separately to complete the upper.
Follow all manufacturer instructions and safe handling practices.
Ensure compliance with all applicable federal, state, and local laws.
