In addition to greater production by established AR15 outfits, each and every Firearm company that has a pulse seems to be producing some version of an AR-15 today. 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 2 brothers, Mark and Chuck Larson, who worked out of a garage. It has grown steadily ever since as well as now employs in excess of ninety folks. Although Rock River produces firearms for numerous federal agencies, the particular majority of their product sales are to the civilian marketplace. Rock River Arms offers fifty or so versions of rifles, however shoppers can make up their own designs, making use of countless parts alternatives - sights, rails, stocks, barrel length and contour, and more. Rock River will also include add-ons like flashlights and red dot sights. Roc k River Arms is like an a la carte workshop for guns. Rock River does not make numerous parts on site. Rock River designs and spec components, then receive them, perform inspections, finish them, assemble them into weapons and ship them out. The Rock River Arms facility is actually complete with a buffing and blasting room, where raw forgings become completed parts. Rock River Arms is truly 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 manufacturing 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 u pper half for the AR15 rifle.Components are measured and examined as they come in to the production 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 examine the dimensions of the chamber. The bolt of a rifle should close 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 lb weight from the trigger. If the weight does not 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 ri fle, 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.Preparation for the firing test begins with the loading of magazines which is a full time job. The finisher snaps 20-30 rounds into waiting magazines in preparation for the final function testSeveral times a day, assemblers and rifle testers load the Rock River van with weapons and take all of them out to the range. Shooting from the back of the vehicle, each and every Firearm with sights i s sighted in, and then test-fired for function. Testers shoot at least two magazines through the fully automatic guns. Who says semi automatics are not accurate? With barrels provided by Wilson Barrel, the main allure of Rock River Arms rifles is that they shoot much better than advertised.Thanks to Rock River Arms Tactical Rifle AR-15 Model BB2512 Rock River Arms light weight, it is painless to carry and the Rock River Arms AR-15 AR15 Model BB2512 Rock River Arms Tactical Operator 2 is even simpler and easier to shoot. Fabricated with completely leading-grade materials and built to the strictest criteria, this Rock River Arms AR15 BB2512 Tactical Operator 2 is unbelievably precise, durable, and well-performing, and makes a superior addition to any Firearm collection.The Rock River Arms Tactical Rifle AR15 BB2512 Tactical Operator 2 rifle includes a Rock River Arms winter trigger guard and the ERGO Sure Grip. While I prefer a hard pist ol grip, I have long endorsed 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 doesn't have child-size hands, and they encourage poor shooting technique by putting the second joint of the finger on the trigger. After market grips such as the ERGO correct that dilemma. The rifles are furnished 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 accustomed to. When I first acquired the Operator and tried the trigger, I was really pleasantly surprised. As a general rule, production line triggers on AR-15s are awful. 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 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.I also shot the Operator alongside another AR-15 with no brake, just a standard A2 birdcage flash hider, and the Operators brake did not seem to be noticeably louder. This is an important consideration when using a rifle indoors.Here are the technical specs just as shipped through my online dealer.Manufacturer Rock River ArmsModel: Tactical Operator 2 Series Type: direct-impingement AR semi auto Capacity: accepts AR-15 magazines of any capacity Caliber: 5.56 NATO chamber Barrel length: 16-inches chrome moly, 1:9" twist Overall length: 37 inches Weight: 7.2 pounds-8.0 pounds (depending on hand-guard style) Hand guard: Varies between models with Half Quad Midlength / Half Quad Carbine/ Full Quad Carbine) Stock: RRA Operator CAR compartment stock, ERGO Sure Grip pistol grip Sights: post front; wind age-adjustable rear aperture Trigger : RRA 2 Stage Match, 4.5 lbs.

Abbreviations: FMJ, full metal jacket; HP, hollowpoint; SP, softpoint.It is easy to get great groups from a sub-par 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 trigge rs that enable the user to get the most out of them.Most dealers in my area wanted retail plus which did not set well with my budget. I purchased my Operator from Class 3 Weapons in Houston Texas at a sizeable savings of only $969.00 which included shipping.
