The 18-inch stainless steel barrel has a 1:10 twist, short flutes near the muzzle, and factory threading capped by a multi-port muzzle brake. The excellent bore condition and sharp rifling are consistent with careful prior use.
Furniture and rails are set up for versatility and control. The 15-inch free-float M-LOK V-Rail handguard includes textured panels and a DB crest, with a Picatinny rail on the receiver and rail sections on the handguard. The stock is a 6-position collapsible carbine unit in black with an approximate 11–14 in. length-of-pull range, paired with a Magpul black polymer pistol grip.
The receivers are aluminum with a Flat Dark Earth finish. Markings include "CAL. MULTI" on the receiver, "308 WIN" on the ejection-port cover, and "DB .308 CAL 1/10" on the barrel. The factory item code aligns with this configuration, and the receiver serial matches the carton label.
