Specna Arms SA-E02 EDGE Series RRA Rock River Arms M4 SBR AEG

SA-E02 EDGE™ Carbine Replica

EDGE™ is a line of replicas by Specna Arms that combines an array of solutions and technologies hard to find in other replicas on the market. It is a series that puts stress on very good craftsmanship of the exterior, solutions that improve upon the versatility of the replica, prolong its lifetime, simplify the diagnostics of a malfunction as well as facilitate the possibility of a power tuning. Straight out of the box you get a replica that does not require any modification, however, if needed - they will be extremely simple. 

The replica features complete, licensed markings of the firearms manufacturer - Rock River Arms. It is a firearm parts and accessories manufacturer, but most of all, a manufacturer of high-quality AR-15 carbines. The company was founded in 1996 by Larson brothers in cooperation with Les Baer and it is based in Colona, Illinois. Today, RRA supplies under a contract AR-15 carbines to anti-narcotic DEA agency, FBI or US Marshals.

Every element of the replica had been made and fitted with the utmost care for every detail. In addition, the body features a Nano Coating finish that prevents scratches. The body also bears deeply engraved Rock River Arms markings as well as an individual serial number further authenticated by an additional hologram. Details that deserve note also include the QD pistol grip that provides easy and rapid access to the motor without having to use tools as well as a double-sided loop for the attachment of a tactical sling.

SA-E02 carbine replica is equipped with a classic, short, polymer handguard. The barrel features a muzzle device on a 14 mm CCW thread. The top RIS rail features a transport handle with an aperture sight.  

The carbine features a factory-fitted MOSFET X-ASR module by Polish GATE. It is an unprecedented cooperation between a Polish manufacturer and a factory known for its airsoft replicas. The highest-quality MOSFET X-ASR looks after the safety of the replica components, improves the trigger reaction and extends the lifetime of electronics and the battery. It will also enable diagnosing basic malfunctions inside the replica thanks to integrated status diodes. 

The replica features an internal precision barrel with 6.03 mm in diameter that provides high accuracy and repeatability of fired shots. The barrel works in tandem with a new type of a Hop-Up rotary chamber that allows for a very precise and stable adjustment of the BB spin. 

The replica features an ESA™ Quick Spring Exchange System. Due to that system, it is possible to rapidly and quickly adapt the power of the replica to the conditions expected on the playing field without the necessity to have the access to a workshop or a set of special tools - all that is required is to remove the stock slide in order to gain access to the spring so that it can be removed without having to pull out or disassemble the gearbox. 

The advantages of the ESA™ system are hard to overstate. In the light of current internal regulations inside various groups, the system guarantees the user a varied set of possibilities and plenty of freedom. ESA™ system allows with a minimal amount of time to exchange the main spring, thus to customize the muzzle velocity towards the area of the game in such a way so as to guarantee an ideal compromise between the effectiveness of fire and the safety for the user himself as well as other participants. Inside the box, along with the replica, is another M90 main spring that is excellent for indoor operations.

The heart of the replica consists of the ORION gearbox based on a reinforced frame and equipped with the function of the main spring release. The replica features an arrays of high-grade parts right out of the box, which makes it characteristic for its reliability and preparedness for further tuning.
