In addition to improved production by recognized AR15 suppliers, [link widoczny dla zalogowanych] every firearm producer that has a heartbeat seems to be crafting some edition 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 2 brothers, Mark and Chuck Larson, who worked out of a garage. It has developed steadily ever since as well as today employs over 90 folks. Even though Rock River produces firearms for several government agencies, the actual vast majority of their sales are to the civilian market place. Rock River Arms offers 50 or so versions of weapons, but [link widoczny dla zalogowanych] shoppers can make up their very own designs, using countless components substitutions - sights, rails, stocks, barrel length and contour, and more. Rock River will also include accessories like flashlights and red dot sights. Rock River Arms is like an a la carte workshop for firearms. Rock River doesn't make numerous parts on site. [link widoczny dla zalogowanych] Rock River designs and spec parts, then receive them, perform inspections, complete them, assemble them into rifles and ship them out. The Rock River Arms facility is actually complete with a buffing and blasting room, [link widoczny dla zalogowanych] where raw forgings become finished parts. Rock River Arms is definitely 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 manufacturing facility there were many boxes of rifle carrier groups, essentially the bolts of the rifles. [link widoczny dla zalogowanych] 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 buy 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 throughout the production stage. Components are tested for hardness. When testing is finished the come together at the respective assembly stations. Care is taken with every step of the upper and lower assemblies. Uppers are matched with various barrels and lowers are assembles usually are assembled with National Match triggers at 4 lbs and various stock combinations.
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 [link widoczny dla zalogowanych] 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 [link widoczny dla zalogowanych] in preparation for the final function test
Several times a day, assemblers and rifle testers load the Rock River van with rifles and take all of them out to the range. Shooting from the back of the van, each and every firearm with sights is sighted in, and then test-fired for function. Testers shoot at least two magazines through the fully [link widoczny dla zalogowanych] automatic guns. Who says semi automatics aren't accurate? With barrels provided by Wilson Barrel, the main attraction of Rock River Arms [link widoczny dla zalogowanych] rifles is that they shoot considerably better than advertised.
Thanks to Rock River Arms Tactical Rifle AR-15 BB2522 Operator 2 light-weight, it's convenient to transport and the Rock River Arms AR15 Model BB2522 Rock River Arms Operator 2 is even simpler and easier to shoot. Created with completely top-grade components and made to the strictest specs, this Rock River Arms AR-15 AR-15 Model BB2522 Rock River Arms is very accurate, [link widoczny dla zalogowanych] resilient, and dependable, and makes a tremendous addition to any weapon collection.
The Operator butts tock itself is a six-position CAR-type assembly with watertight storage compartments and a number of sling connection points. The stock has a ribbed rubber butt pad that slides down with a push-button release to reveal the two storage compartments, sealed with O-rings. Each will hold either two AA batteries or 3 CR123 lithium batteries. As part of the package I had my choice of four rear sights: a traditional bolt-on A2 carry handle; a stand-alone rear sight; a RRA Dominator2 with an raised rail designed especially for use with the EOTech Holosight; or the RRA tactical carry handle that features an elevated rail just below the level of the sights. The mil-spec magazines supplied with all Operator 2 Models are manufactured by NHMTG (Colt). For range work I equipped the Operator with a stand-alone rear sight behind an Aimpoint Comp [link widoczny dla zalogowanych] ML2, and [link widoczny dla zalogowanych] then tried the Operator with a Dominator2 rear sight from a friend combined with an EOTech 512 (AA battery model). For reliability testing I used a Trijicon 4x32 ACOG with no sights.
Now, I realize that even without brakes .223s just don't recoil all that much, especially when compared to the bolt-action sporter-weight rifles chambered in big game calibers. That said, these rifles 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.
