When the name Remington enters the conversation regarding rifles, a tone of seriousness ensues. Known for its quality and accuracy, Remington has built a reputation around the world as a producer of gold-standard rifles. With the bar set this high, it is always of major interest when a new rifle emerges from the craftsmen at Remington. The latest one to hit the bench is the Remington R10.

Many tactical writers these days would say the R10 is an AR-platform “tack driver.” It delivers a heavyweight punch in a lightweight platform without sacrificing accuracy or durability. The rifle design was conceptualized, redesigned and optimized to create one of the best 7.62mm NATO platforms available. Primarily built for the military and law enforcement markets, the R10 provides a versatile and reliable weapon for duty.

Remington R10: Built For Duty

The R10 is the non-suppressed version of the Remington Compact Semi-Automatic Sniper System (CSASS). In formal terms, the Remington R10 is an advanced, modular, semi-auto, AR-platform carbine designed around the 7.62mm NATO/.308 Winchester cartridge with dimensions and ergonomics comparable to conventional AR-15 carbines in 5.56mm NATO.

The direct-impingement R10 starts with forged 7075-T6 aluminum upper and lower receivers that have been hardcoat anodized black. The upper features a 16-inch barrel with a 1-in-10-inch twist rate (though other barrel lengths will be available) and is equipped with an Advanced Armament Corporation (AAC) Blackout muzzle brake. The muzzle features 5/8×24-tpi threading so it’s easy to install other muzzle devices.

Surrounding the barrel and carbine-length gas system is Remington’s RAHG handguard—the same one used on the Remington M2010, MSR/PSR and R4-RGP—with a fixed top rail, and users can add Picatinny rail sections along the seven other sides to mount other mission-critical accessories. In other words, the handguard is very low profile while still offering maximum adaptability. The rifle also comes with flip-up front and rear sights. The handguard also offers six quick-detach (QD) sling swivel sockets—three on each side—with four near the muzzle and two near the receiver. Finally, you’ll notice a grooved handhold on the bottom of the handguard where it interfaces with the receiver. This provides a good grip for shooters who prefer a tighter hold on the gun.

The lower receiver features fully ambidextrous controls, including the magazine release, bolt release and safety. The magazine and bolt releases are integral to the receiver for rugged reliability. Within the enlarged, glove-friendly triggerguard is a single-stage trigger unit. The flared magazine well is designed to accept 10- and 20-round magazines, and my test model R10 came with one 20-round magazine.

The mil-spec-sized receiver extension, or buffer tube, is equipped with a polymer Magpul STR stock that can be adjusted to six different length-of-pull positions. This pairs nicely with a Magpul MOE pistol grip, another gold standard in terms of AR ergonomics.

Proving Grounds

While the Remington R10 has an impressive pedigree, we needed to test it a bit on the range. Our range time included not only basic accuracy testing, but more dynamic applications as well. To measure the test gun’s accuracy, we mounted a Leupold 3-18x44mm Mark 6 riflescope. After a brief zeroing-in period, we were ready to shoot groups.
