Tactical rifle decision time? How about the Rock River Arms Tactical Rifle AR15 BB2512 Tactical Oper In аddіtion tо enhanсеd рrоductiоn by rесоgnizеd AR15 busineѕsеs, еаch аnd everу firearm manufaсturеr thаt haѕ а pulse ѕееms tо bе mаkіng ѕome variаtion оf an AR-15 nоw. Hаlf оf thоѕе riflеs arе dіrеct-imрingemеnt tуpеs wіth the sаme ѕolid dеsign еnvisiоnеd bу Eugеne Stоner when іt wаs fіrѕt intrоduced mоrе than 40 yеаrѕ аgо. Rock River Arms was launched 11 years ago by 2 brothers, Mark and Chuck Larson, who worked out of a garage. It has grown gradually ever since and now employs more than 90 folks. Although Rock River produces guns for numerous govt agencies, the vast majority of their product sales are to the civilian sector. Rock River Arms offers fifty or so models of rifles, but customers can make up their own designs, using countless components substitutions - sights, rails, stocks, barrel length and contour, and more. Rock River will also add accessories like flashlights and red dot sights. Rock River Arms is like an a la carte workshop for weapons. Rock River does not make many components on site. Rock River designs and spec components, 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 room, where raw forgings become finished 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 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 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 as well as 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 examine the dimensions of the chamber. The bolt of a gun should close 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 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 rifle, this lower half could also be matched to an endless combination of barrel lengths, barrel contour, hand-guards and calibers. Once uppers and lowers are joined to complete the final rifle configuration they are tagged and ready for test firing. All rifles are custom built according to customer specifications. 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 are 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. 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 test Several times a day, assemblers and rifle testers load the Rock River van with weapons 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 are not accurate? With barrels provided by Wilson Barrel, the principal appeal of Rock River Arms rifles is that they shoot significantly better than advertised. Thanks to Rock River Arms AR15 Model BB2512 Rock River Arms Tactical Operator 2 light weight, it's easy to haul and the Rock River Arms AR-15 AR15 BB2512 Tactical Operator 2 is even less difficult to fire. Manufactured with completely top-grade materials and built to the strictest requirements, this Rock River Arms AR-15 AR15 BB2512 Tactical Operator 2 is incredibly precise, long-lasting, and reliable, and makes a very good improvement to any gun collection. All Tactical Operator 2 rifles feature flat-top receivers and 16-inch chrome moly 1:9" twist barrels with 5.56 NATO chambers, tipped with the RRA Tactical Muzzle Brake. I purchased the Rock River Arms AR-15 AR15 Model BB2512 Rock River Arms Tactical Operator 2. I found the BB2512 Operator was the most unusual-looking member of the group with its gas system and a unique Free Float hand guard. The light, two-stage trigger was a welcome asset in speed drills, but not as much as when shooting the Operators from the bench. If you've ever had to wrestle with a heavy, gritty AR trigger when attempting to shoot groups, you know just how difficult that can be.

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 mediocre 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. Rock River Arms AR-15 AR15 Model BB2512 Rock River Arms has a list price of 1515.00. I ended up ordering it over the internet for much less. Nearly all dealers in my location required list price ... plus which did not set well with my spending plan. I acquired my Rock River Arms AR-15 Model BB2512 Rock River Arms Tactical Operator 2 from Class 3 Weapons at a significant cost savings. Rock River Arms is at this time promoting the Operator rifles as a package deal, with the rifle of your choice equipped with its National Match two-stage trigger, any one of four rear sights, a one-inch or 30mm Hi-Rise scope mount, two 30-round magazines and a case. These bundles start at an incredibly economical price of $1,000 according to the RRA factory website. I ended up purchasing it online for much less. Most dealers in my vicinity desired retail plus which did not set well with my budget. I purchased my Operator from Class 3 Weapons in Houston Texas at a substantial savings of only $969.00 which included shipping. Based on where you live your cost will deviate based on shipping and taxes if relevant. For the time being, thanks Rock River for a awesome firearm and keep up the good work. I'm off to the community firing range to discover what this power house is capable of doing again. Best tactical rifle at the best price, Rock River Arms Tactical Rifle AR15 Model BB2512 Rock River Arms Firearm, Rock River Arms Tactical Rifle, I searched the internet for the new Rock River Arms AR-15 Model BB2512 Rock River Arms Weapon, After a long search I decided on the Rock River Arms Tactical Rifle AR15 Model BB2512 Rock River Arms Rifle | | Wednesday, September 14th, 2011 | | 3:12 pm |

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 firearm testers load the Rock River vehicle 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 automatic guns. Who says semi automatics are not accurate? With barrels provided by Wilson Barrel, the principal appeal of Rock River Arms rifles is that they shoot significantly better than advertised. The fit and finish of the Tactical Operator 2 firearms are fantastic and undoubtedly a step above the normal, rack-grade, Parkerized mil-spec AR on the market these days, although they are barely more expensive than those lesser grade types. The Operators upper and lower receivers fit together so strongly I needed a tool to work out the push pins. While the Rock River Arms Operators don't have pistons or monolithic fore-ends or flip-down rear sights, they have everything you need in an accurate, reliable semiautomatic rifle, at a price that in the past would have been unheard of. The Rock River Arms AR-15 Model BB2512 Rock River Arms Tactical Operator 2 is created with a 16 1/2" Chrome Moly barrel for accuracy, Rock River Arms Tactical Muzzle Break with exceptional signature reduction, Flip forward sight, Rock River Arm Quad-rail hand guard and much more... The Rock River Arms AR15 BB2512 Tactical Operator 2 also contains such quality enhancements as rugged fixed rear sight and flip forward sight to give you even more resilience and aesthetic appeal. With the forward flip sight feature, the Rock River Arms AR-15 Model BB2512 Rock River Arms Tactical Operator 2 is ready for action to further add a scope or red dot. The Rock River Arms Tactical Rifle AR15 Model BB2512 Rock River Arms Tactical 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 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 placing the second joint of the finger on the trigger. After market grips such as the ERGO correct that downside. 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 accustomed to. When I first acquired the Operator and tried the trigger, I was really shocked. As a general rule, factory triggers on AR-15s are unpleasant. 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 prior to 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. You never know if you are going to like a gun unless you shoot it, and I was very curious how well the RRA Tactical Muzzle Brake would perform. It looked well-designed, not to mention cool, but that was no assurance it would really work. It worked especially well. When engaging targets at 10 yards with the Entry Operator equipped with an Aimpoint, I discovered that under full recoil the Aimpoint dot moved upward one inch on the target before falling back down to its original spot. This is outstanding performance from a brake. I then experimented with the Operator on some IPSC targets at urban engagement distances. With the help of the muzzle break, the muzzle did not move upward at all, even during rapid fire, I have to say, that the brake appeared to work really well. Between the efficient brake and the light trigger, how quickly I might hit targets inside 25 yards with follow-up shots was entirely a test of how fast I could pull the trigger.
