Davidson Defense Silver Fang 7.5-inch Pistol-Gas 1:7 5.56 NATO AR-15 Tubular Pistol Complete Upper Build

Silver Fang 7.5-inch 5.56 NATO AR-15 Complete Upper

The Silver Fang is built around a Bear Creek Arsenal "Gael" 7.5-inch 5.56 NATO barrel, machined from stainless steel, paired with a "Panhead" billet upper receiver machined in a NOFA configuration with a .458-size ejection port. It pairs a 7-inch MFFAR7 free-float smooth handguard with an AR-15 A2 GI birdcage flash hider at the muzzle, running on a pistol-length gas system. A complete bolt carrier group and Mil-Spec charging handle round out the upper, giving the buyer everything needed on the upper side.

Barrel and Gas System

The "Gael" barrel runs 7.5 inches long, chambered in 5.56 NATO and machined from stainless steel, giving it strong corrosion resistance across years of use. It carries a 1:7 twist rate suited to stabilizing a wide range of 5.56/.223 bullet weights, along with a 1/2x28 muzzle thread. Gas cycles back to the action through a compact pistol-length system, running a pistol-length gas tube paired with a micro low-profile steel gas block sized to a .750-inch diameter, keeping the profile slim beneath the handguard.

Upper Receiver and Handguard

The upper receiver is a "Panhead" billet unit, machined in a NOFA configuration that leaves the receiver's side profile smooth and uninterrupted without a forward assist boss. It features a .458-size ejection port with a standard .223/5.56 door, rod, and spring installed for reliable case ejection. Over the barrel sits a 7-inch MFFAR7 handguard, a smooth, free-float design that isolates the barrel from handguard pressure for consistent accuracy while keeping a clean, low-profile look along the forend.

Muzzle Device

Capping the muzzle is an AR-15 A2 GI birdcage flash hider, a proven, time-tested design that helps suppress muzzle flash during firing. It threads onto the barrel's 1/2x28 pattern and is locked into its final timed position with the included 1/2-inch black crush washer.

Bolt Carrier Group and Charging Handle

A complete AR-15 bolt carrier group is included, made in the USA and listed for use across 5.56 NATO, .223 Remington, .300 Blackout, and .350 Legend. That broader listing describes the BCG itself; the barrel and chambering on this upper remain 5.56 NATO. A Mil-Spec AR-15 M4 charging handle rounds out the upper's operating components.
