COBALT KINETICS OVERWATCH-XL P.R.S. SCORES HIGH ON ACCURACY
If someone would have told me 10 or 20 years ago that a gas gun in a caliber less than .308 Winchester would outshoot any of my military-grade bolt-action sniper rifles for accuracy, as well as distance, I would have called them either insane, or a liar, or probably both.
After test-firing the Cobalt Kinetics Overwatch-xl P.R.S. in 6.5 Creedmoor, I am finally willing to concede that point. Yes, now it can be done!
Hyperbole aside, semi-automatic precision rifles have been improving every year. No longer are our military and police snipers necessarily slaves to the bolt-action, or conceding with archaic semi-auto rifles that compromise on accuracy.
All of Cobalt Kinetics’ rifles are custombuilt, one at a time. These are not mass-produced, cookie-cutter rifles, but true custom guns from the ground up. The XL designation means that it is built on Cobalt’s larger-frame, or Ar-10-size rifle, and the rifle will accept Magpul 308-pattern double-stack magazines. There are Overwatch rifles built on the Ar-15-size receivers in the shorter calibers like .223 Remington and .224 Valkyrie as well.
Cobalt Kinetics builds all their receivers and handguards out of 7075 aluminum, making for the strongest aluminum you can use in a rifle build. In turn, these are hard anodized with a Type 3 coating and then Cerakoted over the anodizing. This makes for probably the most advanced and superior coating that we have ever seen on any firearm. The heart of this rifle is a match-grade 24-inch full-profile barrel, crafted from stress-free 416-R stainless steel. For those not familiar with the term, 416-R is formulated specifically for gun barrels. It has a minimal amount
of chromium (the metal that makes stainless steel “stainless”) and it is still susceptible to corrosion, but nowhere near that of plain carbon steel. The free-machining characteristics of the steel make it perfect for high-definition rifling and crowning. It allows the gun maker to craft a more accurate barrel.
Cobalt’s bolt carrier is made of 8620 steel, which is a case-hardening steel-containing nickel, chromium and molybdenum as alloying elements. The cam shaft in your vehicle may be made out of this same steel. The bolt head is made of 9310 steel, which is similar to 8620, but is more likely to be used in the construction of a tractor-trailer crankshaft or landing gear of an aircraft. A lithium-iron surface conversion (or Life) is used to treat these components and it increases the steel’s hardness, strength, and resistance to erosion. The bolt is micro-polished and QPQ (Quench Polish Quench) finished; this is a modern and very advanced form of case hardening through nitro carbonizing that creates an iron oxide layer to inhibit rust.
If you are unfamiliar with Cobalt’s rifles, you may think there are two forward assists, and while I have always
thought that the forward assist was the most useless feature attached to the AR-15/M16/M4 platform, in this case, it is not.
Each one will function like a forward assist, and if you think it is a good idea to force a high-pressure cartridge into a chamber that is not allowing it, then more power to you. In the case of a Cobalt Kinetics rifle, there is a better reason for their presence: they allow the shooter to send the bolt home by using the thumb of the shooting hand without releasing the hold on the rifle. The trigger finger can remain indexed without having to search for a bolt catch extension.
Speaking of the trigger, the Overwatch ships with a Timney Targa two-stage trigger that breaks like glass. The rail system is fully M-LOK compatible and the stock incorporates a Delrin bag
When running a riflescope on any AR, it can be tough to get hold of a standard charging handle. The wings of the Radian Raptor charging handle protrude far enough to give you an easy grasp.
The Pro Muzzle Brake utilizes a symmetrical linear array of five intersecting spheroid cuts that vent the blast to the sides in order to reduce dust signature and prevent muzzle rise.
