In addition to increased production by recognized AR15 companies, each and every firearm producer that has a pulse seems to be making some model of an AR-15 now. 50 % of those rifles are direct-impingement types with the same solid design envisioned by Eugene Stoner when it was first introduced more than 40 years ago.
Rock River Arms was launched 11 years ago by two brothers, Mark and Chuck Larson, who worked out of a garage. It has developed continuously ever since as well as now employs in excess of ninety folks. Although Rock River produces guns for numerous federal agencies, the particular majority of their sales are to the civilian market. Rock River Arms offers fifty or so designs of rifles, however customers can make up their very own designs, utilizing numerous components alternatives - sights, rails, stocks, barrel length and contour, and more. Rock River will additionally add accessories like flashlights and red dot sights. Rock River Arms is like an a la carte workshop for weapons. Rock River doesn’t make numerous parts on site. Rock River designs and spec parts, then receive them, perform inspections, complete them, assemble them into weapons and ship them out. The RRA factory is complete with a buffing and blasting room, where raw forgings become completed parts. Rock River Arms is genuinely a family 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 facility 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 and tested 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 firearm should close up over the green “go” gauge but not close over the red “no go,” which is slightly oversized. Cartridges can rupture, sometimes 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 desired 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 pound 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.
All rifles are built to customers specifications and each lower and upper is unique
In the shipping area, parts come in, guns go out. There seems to be no end to the demand. Rifles usually are sitting on dealers’ shelves for a few days before they’re gone. For dealers that take deposits, guns never even make it to the shelves before they are picked up by a local customer or shipped out again.
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 vehicle with rifles and take all of them away to the range. Shooting from the back of the van, 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 main attraction of Rock River Arms rifles is that they shoot far better than marketed.
Thanks to Rock River Arms AR-15 Model BB2522 Rock River Arms light-weight, it is painless to carry around and the Rock River Arms AR-15 AR-15 Model BB2522 Rock River Arms is even much simpler to shoot. Constructed with entirely leading-grade components and made to the strictest requirements, this Rock River Arms AR-15 AR15 Model BB2522 Rock River Arms Operator 2 is remarkably precise, durable, and dependable, and makes a excellent improvement to any rifle 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 advocated 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. Replacement grips such as the ERGO correct that drawback. 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 appearance of the mil-spec design better probably because its what I am used to. When I first picked up the Operator and tried the trigger, I was really 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 4 pounds -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.
Now, I understand that even without brakes .223s just don't recoil all that much, particularly when compared to the bolt-action sporter-weight rifles chambered in big game calibers. That said, these weapons are designed for use in competition or self-defense, where rapid, accurate follow-up shots might sometimes be the difference between winning and losing. And in a self-defense situation, second place is not where you want to be.

Notes: Accuracy results are the averages of four five-shot groups at 100 yards from a sandbag rest. Velocities are averages of three shots measured with an F-1 Alpha chronograph 12 feet from the muzzle. Abbreviations: FMJ, full metal jacket; HP, hollowpoint; SP, softpoint.
It is easy to get great groups from a average rifle if it has a great trigger, but put a tack-driver with a gritty eight-pound trigger in anybody's hands, and they will be lucky to stay on paper. The Rock River Arms Operator rifles are not just inherently accurate (that's one plus to the AR design), they are equipped with quality triggers that enable the user to get the most out of them.
