The heart of this build is a Remington 870 Tactical 12-gauge pump-action with an 18.5-inch barrel, extended magazine tube, and a 6+1 stated capacity. It loads from the bottom and ejects to the right, with a steel receiver marked "Remington 870 TACTICAL" and a matte black finish.
An ATI collapsible AR-style buttstock with pistol grip is installed, providing an adjustable length of pull from 11 to 14.5 inches. A buttstock-mounted shotshell carrier keeps extra rounds at hand without adding bulk to the forend.
A ventilated metal barrel heat shield is fitted. Open sights—front post and rear notch—offer quick alignment.
At the muzzle, an extended ported breacher-style stand-off device is installed. Illumination is handled by an M3 Tactical Illuminator weapon light. A magazine tube clamp with a sling-swivel stud provides added support for the extended tube and sling attachment.
