The receiver is rollmarked "Remington MODEL 700 AAC–SD," and the barrel is marked "REMINGTON ARMS COMPANY INC. ILION, NY 300 AAC BLACKOUT." Both the receiver and barrel wear a uniform, non-reflective matte black finish. A 2D matrix/QR-style code is present adjacent to the serial on the receiver.
The 16.5-inch carbon-steel barrel is hammer-forged with a heavy contour and crisp 1:7 rifling. The muzzle is externally threaded 5/8x24 to accept compatible devices. The bore presents a clean, mirror finish with sharp lands and grooves.
This is a steel short-action receiver configured as a barreled action only. It reflects the AAC-SD series traits in .300 AAC Blackout, including the heavy barrel profile and factory threading. The internal box length is 2.931 inches (74.5 mm).
The AAC-SD series in 300 BLK was originally positioned for use with threaded muzzle devices, and this example retains the standard 5/8x24 thread pattern. The overall presentation is consistent and clean, with only light signs of prior handling.
