Mossberg 100 All-Terrain Rifle (ATR) #27230 308 Winchester, $200

Read Gun Tests Rating and Recommendation

This line was discontinued in 2014 and evolved into the Patriot series. The Mossberg’s big rail offers easy scope mounting. The rifle was not as smooth as the others, but may be purchased for just over $300 with a credible scope. The rifle did not misfeed. We liked the cheek rest. The primary problem was accuracy.

The ATR is a credible choice with decent performance, especially when fitted with a Vanguard scope that cost 150% more than the rifle itself. It included a Weaver-style rail for mounting optics. This rifle simply wasn’t very accurate.
The elliptical bolt handle offered easy lift and ejection action. It wasn’t difficult to cycle the action and get a fast follow-up shot. The lever-style safety (arrow) was positive in operation.
The trigger was set at 2.5 pounds without difficulty. It was unusual in this test to have all adjustable trigger function. Ten years ago, adjustable triggers were almost the sole province of aftermarket builders.
