The History of Cooper

Cooper was established in 1990 by Dan Cooper and two former employees of Kimber of Oregon. Initially, the company focused on the production of hunting rifles, specifically those used for varmint hunting. Their initial product line included the Model 36 TRP-1, part of their Target Rifle Project-Phase 1, and the Model 38 in 22CCM, intended for sports shooting.

In 1993, they started testing a one-shot varmint rifle in .223 Remington, leading to the development of the three-lug bolt action Model 21 also known as "Varmint Extreme". In 1998, the company underwent a rebranding, adopting the name "Cooper Firearms of Montana, Inc." and marking its products accordingly. That year, they introduced Models 21 and 22, collectively known as "Varminter", and expanded their range with the Model 57, which later evolved into Model 57M in 2001. They also added new stock designs to their offer in 2005.

2007 marked the introduction of the Model 52, designed for use with .30-06 cartridges. However, 2008 was a challenging year for the company, with a controversy surrounding Dan Cooper's financial support to a pro-gun control presidential candidate Barack Obama. This resulted in Cooper stepping down from his CEO position. Following this period, the company continued to innovate with the release of models like the short action repeater Model 54 in 2009, and the Model 56, accommodating various magnum calibers, in 2010.

Fast forward to 2023, Nighthawk Custom of Arkansas acquired Cooper Firearms of Montana, and the production facilities were transferred to Arkansas, USA. In February 2023, Nighthawk communicated to Cooper customers that they had acquired Cooper's assets, including the brand name, intellectual properties, and inventory, after a team visit to Montana in December. They relocated these assets to Arkansas and are planning to manufacture new Cooper rifles there, with operations expected to start in late 2023.

Cooper Model 92 Rifle Review

The Cooper Model 92 is a bolt-action rifle featuring a lighter version of the Model 52's action. The three-lug locking system is consistent with other Cooper models, and the extractor operates on a spring-tensioned rotation. The ejection system, however, is different in the Model 92, having a spring-loaded plunger located at the front of the bolt, as opposed to the Model 52's pivoting-blade ejector in the receiver bridge. Except for differences in the caliber choice, other structural components remain on par with model 52.

The Model 92 features a 24-inch light contour barrel, made of stainless steel and fluted for lighter weight. The rifle comes with a detachable steel magazine, with a capacity of three rounds. Every model incorporates a bolt release lever located on the receiver's right side. The receiver is drilled and tapped to allow scope mounting, and some models are supplied with pre-installed mounting bases.

The safety mechanism comes in a form of a two-position safety lever, positioned on the side of the bolt handle. Pulling the lever rearward disables the trigger, but bolt operation is unaffected. Pushing the lever forward reveals a red dot on the indicator, signifying the rifle is cocked and ready to be fired.

The single-stage trigger mechanism includes adjustments for over-travel, sear engagement, and the weight of pull that ranges from 680 to 1814 grams (1.5-4 lbs). The 92 models are available in various stocks and different finishes.
