Davidson Defense Lawman's Decree 14.5-inch Mid-Gas 1:7 5.56 NATO AR-15 Tubular M-Lok Pistol Complete Upper Build

Lawman's Decree 14.5-inch 5.56 NATO AR-15 Complete Upper

The Lawman's Decree is built around a 14.5-inch 5.56 NATO barrel with a medium profile, finished in nitride, paired with a 7075-T6 aluminum upper receiver finished in black anodizing. It pairs a 12.5-inch tubular aluminum M-LOK handguard with an A2 GI birdcage flash hider at the muzzle, running on a mid-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 barrel runs 14.5 inches long, chambered in 5.56 NATO and built from 4150 chrome moly vanadium steel with a nitride finish and medium profile. It carries a 1:7 twist rate and a 1/2x28 muzzle thread. Gas cycles back to the action through a mid-length system, running a stainless steel mid-length gas tube and a micro low-profile steel gas block sized to a .750-inch journal.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished in black anodizing, cut with M4 feed ramps for smooth feeding and fitted with an AR-15 forward assist assembly. The ejection port carries a standard .223/5.56 door with its rod and spring installed. Over the barrel sits a 12.5-inch tubular handguard machined from aluminum with a 1.77-inch internal diameter, built in a Suppressor-Ready design, using an M-LOK attachment system along its length.

Muzzle Device

Capping the muzzle is an A2 GI birdcage flash hider, compatible with both 5.56 NATO and .223 Remington. It threads onto the barrel's 1/2x28 pattern and is secured in its final timed position with a 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.
