Remington CSR: Out of Hiding

The Remington Concealable Sniper Rifle is a lot like upgrading from a Motorola Razr to the iPhone X — you didn’t know what you were missing until it’s in your life.. Remember when smartphones weren’t readily available? And now, you can’t imagine life without access to such life-changing advancements? In a nutshell, this is how we feel about the CSR.

The CSR impacted us way back in 2014. We’ve been fortunate enough to have been privy to the ins and outs of the CSR and have tried to beat the brakes off it — but to no avail. This rifle quickly became a personal favorite, but it was not available to the public until now with a limited production run.

We were stoked to hear the CSR is finally going to bless others with its advancements in rifle technology. There are a few rifles with similar features, but certainly not all the features. The CSR comes with a hefty price tag, but you get what you pay for.

Similarly so, that paying for the bells-and-whistles smartphone is worth denting your wallet versus the agony of trying to text on a flip phone.

Overview
The Remington CSR was originally designed for its namesake: to be a concealable sniper rifle. This precision tool was made for the most elite warriors the world has ever seen. It was intended to be used during bold, challenging, and curtained missions across the globe. A captivating aspect of the CSR is its purpose and ability to be broken down and reassembled by the end-user and still make hits without re-zeroing. How many rifles would you be willing to at least bet your lunch money it would still hold zero after taking the barrel off in the field and putting it back on? For us, so far, the answer is one.

Genetics of the CSR are based off of Remington’s Modular Sniper Rifle (MSR) and Precision Sniper Rifle (PSR). This family of rifles features the ability to change barrels and calibers within minutes. Not having to tote around a full-length musket, and instead carrying a rifle that fits in a backpack and can be quickly assembled is a unique benefit. While that benefit isn’t necessary for most of us, it undoubtedly has a cool factor.

Straight to the Point
The heart and soul of the CSR is the barrel design. Being able to easily switch out parts on the AR platform has spoiled us. We didn’t expect such user-friendliness from a bolt gun until getting acquainted with the CSR. After being able to fully disassemble the CSR with one tool, our expectations have been upped.

Chambered in 7.62 NATO, the barrel is 4140 hammer-forged steel and melonite-treated. Fluting of the barrel lessens the weight of the rifle without sacrificing accuracy. Melonite-treating barrels improves the barrel life, but is known to be a difficult treatment to control. During the coating process, imperfections and uneven thickness affects barrel accuracy. In order to have the advantages of melonite without the negative effects, Remington thoroughly tested and adapted its process for a more controllable end result. Those improved processes have tightened up the accuracy standard of the CSR/PSR/MSR family. Initial CSR barrel length offerings from Remington includes either a 14-inch or a 16-inch barrel, with 1:7 or 1:10 twist rate, respectively. The 14-inch 1:7 twist is optimized for subsonic ammunition, while the 16-inch 1:10 twist is ideal for supersonic ammunition.

The CSR can be partially or completely disassembled in under 60 seconds.

Akin to an AR barrel extension, the CSR barrel extension looks familiar. Remington says it’s conceptually an M16 extension, but for a bolt action. If you’ve ever built an AR, inserting the barrel into the receiver fits together like Legos. You’d have to severely screw up the simple task if you couldn’t get an AR barrel into the upper receiver. That’s assuming the receiver and barrel are spec’d correctly. Point being, the CSR barrel snugly slides into the receiver in the same manner. The alignment pin and stop shoulder locates the barrel extension against the receiver the same way, every time the barrel is removed and reinserted.

Locking lugs of the bolt lock into the barrel extension. Important for maintaining zero after disassembly is the bigger, beefier extension. While the CSR barrel has similar features to an AR barrel, it will not fit on any other rifles other than the CSR/PSR/MSR series.

The CSR barrel is held in place by a barrel nut that can be quickly removed and reinstalled with the Remington-supplied torque wrench. The torque wrench head slides into cutout holes on the barrel nut. It’s torqued to 20 ft-lb. After a lot of testing, Remington found that 20 ft-lb of torque provided all the needed rigidity and zero retention, while also making the barrel easier to install and remove.

Not Just for Looks
This is a sexy rifle. We would understand if you liked her just for her looks, but every aspect of the design is justified. It’s a beauty and brains kind of rifle. We’ll give a front-to-back rundown.

Seeing as how Advanced Armament Corporation is owned by Remington, it’s not surprising the CSR sports an AAC muzzle device. The AAC BLACKOUT 7.62mm 90T Tapered Flash Hider has Nitride finish and mates to AAC SR7 fast-attach silencers. Since we’ve already covered the barrel, we’ll jump to the bolt.
