    A tactical rifle dream, my Rock River Arms AR15 Model BB2522 Rock River Arms Firearm
    Recently, Rock River Arms released a new series of rifles. The Operator 2 line involves three different versions of Rock River Arms revered direct-gas-operated LAR-15 style rifles. Each will share some typical capabilities, and the weapons take their name from the new Operator stock Rock River Arms has recently released. Rock River Arms started out constructing very nice 1911s, years before it was cool, the Corona, IL, company got into the AR-15 field. Its firearms were so perfectly made that the U.S. Drug Enforcement Agency selected Rock River to produce its issue rifles available currently as the LAR-15 Pro-Series Government Model.

    Rock River Arms was founded 11 years back by 2 brothers, Mark and Chuck Larson, who worked out of a garage. It has grown continuously ever since and today employs more than ninety people. Although Rock River produces guns for numerous government agencies, the vast majority of their sales are to the civilian marketplace. Rock River Arms offers 50 or so versions of weapons, however customers can make up their very own configurations, making use of countless parts substitutions - sights, rails, stocks, barrel length and contour, and more. Rock River will additionally include accessories like flashlights and red dot sights. Rock River Arms is like an a la carte workshop for weapons. Rock River doesn’t make many components on site. Rock River designs and spec parts, then receive them, perform inspections, complete them, assemble them into rifles and ship them out. The RRA factory is complete with a buffing and blasting area, where raw forgings become completed parts. Rock River Arms is genuinely a family small business with the brothers Chuck and Mark Larson as well as their father and one of their sons working at the plant. Looking about the factory there were many boxes of rifle carrier groups, essentially the bolts of the rifles. Rock River Arms offers an almost countless number of chambering options for the basic AR platform. Once you own a lower half which consists of the stock and receiver, you can purchase upper halves (barrel, carrier group, and gas system) in all kinds of chambering and interchange them freely. There's even a company that offers a .410 shotgun upper half for the AR15 rifle.

    Components are measured as well as examined as they arrive in to the manufacturing facility and at various stages during production. Tested for hardness, testing is done all the way down to the flash hider. All of the little sub assemblies - sights, gas blocks, carrier groups, safeties, and so on -- come together at the stations where the upper halves and lower halves are put together. Once at a work station the gunsmith assembles the upper half of what will be a future complete rifle. The gunsmith takes special care to assemble the upper with the silver tube running along the top of the barrel which directs gas from the gas block to run the action. During the upper half assembly, the headspace gauges are used to check the dimensions of the chamber. The bolt of a gun must close up over the green “go” gauge but not close over the red “no go,” which is slightly oversized. Cartridges can rupture, occasionally dangerously, in an oversized chamber. Rock River offers the choice of a standard trigger or a two-stage National Match trigger for serious target shooting. A two stage trigger is the favorite style for military rifle competitions such as the famous National Match at Camp Perry, Ohio. Pulling a two-stage trigger, you feel slack as the trigger moves a short distance, then a light, clean break. The Rock River Arms gunsmith will check the weight of the trigger pull by dangling a 4 1/ 2 lb weight from the trigger. If the weight doesn’t trip the trigger, he will file the trigger sear to lighten the pull. Lighter trigger pulls are also available from leading Rock River Arms dealers. Lowers also come with options such as an oversized winter trigger guard, originally designed for police officers who needed to keep their hands inside warm gloves but still be ready to shoot in cold weather. Winter trigger guards work perfectly for winter coyote hunters as well. As the final pieces are assembled into a lower half of what will be the final rifle, this lower half could also be matched to an endless combination of barrel lengths, barrel contour, hand-guards and calibers.

    As uppers and lowers are joined by a master gunsmith assembler, the firearms are tagged and prepared for the test fire phase of the product.

    The shipping area is a flurry of activity. Parts coming in and rifles going out. A literal symphony in action as the Rock River arms factory pushes in raw components destined to become full rifles. Oddly enough, there seems to be no end in sight as the operation continues day after day.

    Every rifle is sighted in and test fired before it leaves the factory. The Rock River Arms finisher loads the magazines prior to every rifle test fire. Using a fast bench loading tool, the finisher snaps 20-30 rounds into a magazine in an instant.

    Several times a day, assemblers and rifle testers load the Rock River van with weapons and take them out to the range. Shooting from the back of the vehicle, every firearm with sights is sighted in, and then test-fired for function. Testers shoot at least two magazines through the fully automatic guns. Who says semi automatics aren’t accurate? With barrels provided by Wilson Barrel, the primary appeal of Rock River Arms rifles is that they shoot considerably better than advertised.

    Thanks to Rock River Arms AR-15 BB2522 Operator 2 light weight, it is convenient to carry and the Rock River Arms Tactical Rifle AR15 BB2522 Operator 2 is even less difficult to fire. Built with exclusively top-grade components and created to the strictest specs, this Rock River Arms AR15 Model BB2522 Rock River Arms is exceptionally accurate, tough, and dependable, and makes a incredible addition to any gun collection.

    The Rock River Arms Tactical Rifle AR15 BB2522 Operator 2 rifle includes a Rock River Arms winter trigger guard and the ERGO Sure Grip. While I prefer a hard pistol grip, I have long strongly suggested use of pistol grips such as the ERGO that add a little material to the backstrap of the rifle. Standard AR pistol grips are too small for anyone who do not have child-size hands, and they encourage poor shooting technique by putting the second joint of the finger on the trigger. Upgraded grips such as the ERGO correct that dilemma. The rifles are designed with the RRA Star safety/selector, which sticks out a bit more from the receiver than a mil-spec safety. It is not ambidextrous. The safety performed just like it should, but I like the looks of the mil-spec design better probably because its what I'm used to. When I first picked up the Operator and tried out the trigger, I was really pleasantly surprised. As a general rule, factory triggers on AR-15s are horrible. Not so the Operator trigger. Its crisp, light, two-stage trigger that breaks right at four lbs -not what I was expecting at all. This was just before I realized that all the Operator rifles come equipped with Rock River Arms well-respected two-stage National Match trigger system, which includes a lightened hammer.

    The first headache constantly, with any kind of weapon, is consistency, my Operator functioned with not a hitch. I fed the Operator ammo from Wolf, Winchester, Remington and Black Hills, with different bullet weights and types, and the weapons digested it all. I used the provided magazines for testing as well as some surplus magazines I found lying around, along with a a couple of MagPul PMags.

    Here are the specific features just as delivered from my online dealer.

Depending on where you live your cost will fluctuate based on shipping and taxes if relevant. For the time being, thanks Rock River for a awesome firearm and keep up the good work.
