The 100 ATR is chambered in .270 Win and uses a 22-inch sporter-profile, unthreaded barrel for balanced handling. Its matte gray/silver finish complements a carbon-steel receiver, and the rifle is made in the USA.
The push-feed bolt employs a plunger-style ejector and a small extractor. A barrel lock-nut system is used for headspacing, aligning with Mossberg’s practical, serviceable approach to the ATR series.
Feeding is via a blind, internal top-loading box magazine with a 4+1 capacity. The rifle has no iron sights, and the receiver is outfitted with two-piece scope bases and horizontal-split rings that secure the included optic.
The black synthetic stock features a straight comb, molded checkering, and a ventilated recoil pad. Length of pull is 13.5 inches, and the rear sling stud is missing (insert present); the front sling stud boss is cracked/broken and the stud is missing/damaged.
A Simmons 3-9x40mm scope with a duplex reticle is installed, offering versatile 3–9x magnification and a 40mm objective for practical big-game use.
