The Mossberg 100 ATR is an often-overlooked bolt-action rifle designed for hunters and law enforcement working on a limited budget. And it really delivers. Available in many, many different configurations is a handful of popular calibers the ATR (All-Terrain Rifle) cuts costs by implementing a simple construction.
That doesn’t mean that it’s short on features. The 100 ATR comes with an adjustable trigger from the factory, which is especially easy to tune down to a crisp two pounds. It’s called Mossberg’s Lightning Bolt-Action (LBA) trigger. Depending on the model, ATRs come with polymer or wood stocks, standard-profile barrels with or without iron sights and fluted, free-floating barrels.
All ATRs come drilled and tapped for scopes and have Weaver scope bases pre-installed. Most ATRs feed from an internal, integral magazine, which is one way they have cut costs. The magazine is top-loaded through the open bolt. Two variants, however, feed from box magazines, the Mossberg 4×4 and MVP.
The Mossberg 4×4 is available in the ATR calibers, .243 Winchester, .270 Winchester, .308 Winchester and .30-06 Springfield, but also adds .22-250 Remington, 7mm Remington Magnum, 7mm-08 Remington, .300 Winchester Magnum and .338 Winchester Magnum. Mossberg 4x4s also come with an enhanced feature-set, including a ported muzzle break, fluted free-floated barrel. And the 4×4 sells for less than $400, in some configurations, closer to $300.
The MVP or Mossberg Varmint Predator is chambered for high-velocity .223 Remington and 5.56 NATO ammunition. Conveniently it also uses AR-15/STANAG magazines. It also has a medium-profile fluted bull barrel and fluted bolt. Designed with bench-rest shooting in mind as well, it features a more vertical pistol-style grip wood laminate stock. The MVP comes with or without a 4-16x50mm variable riflescope, and runs between $400 and $500.
The Special Purpose “Night Train” was specifically designed for the tactical shooter and police department of limited resources. It comes in two models, digital camo or black, both in .308 Winchester. It has a 22-inch barrel and includes a 4-16x50mm riflescope on a custom Picatinny rail. The Night Train also features a Harris bipod and heavy-duty nylon sling. The Night Train also runs between $400 to 500.
But the shining star of this bargain is the plain-Jane 100 ATR. With its simple and bulletproof magazine, lightweight polymer stocks (and heavier wood stock options) and good selection of calibers, .270 Winchester and .30-06 in long-action, .243 Winchester and .308 Winchester in short action, the vanilla Mossberg ATRs are often priced right around $300, and can be found online for even less.
Whether you’re a new shooter on a budget, an experienced shooter who knows how guns get knocked around or just a fan of great values, the Mossberg ATR is one bolt-action rifle worth looking into.
