RRA SA-C15 CORE™ Carbine Replica

Specna Arms meets the expectations of clients by presenting the CORE™ line of products - an exceptional

series of replicas that introduces a new quality to the market. An attractive price in combination with 

an innovative spring change system as well as high-quality materials make this replica suitable for

beginners and seasoned airsoft players alike.  

CORE series carbine replicas feature complete, licensed markings of the firearms manufacturer -

Rock River Arms. Rock River Arms is an American 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 produces high-quality AR-15

carbines at a reasonable price and in various versions. Since 2003, the company has been contracted to

supply AR-15 carbines to anti-narcotic DEA agency, FBI or US Marshals.

The receiver, the stock slide and an SF stock that holds the battery, as well as the pistol grip, were

made of nylon fiber reinforced polymer. Remaining components such as the barrel, RIS handguard

, flash hider, enlarged charging handle and tactical sling swivels were made of metal (parts made of

steel include the screws, pins, shell ejection window and mock bolt carrier). The receiver bears markings

and a serial number.

The replica’s parts are aligned very well and the User will not experience any loose spots between

the lower and the upper receiver. The use of a light polymer receiver allowed for a reduced weight,

which makes it very suitable for dynamic games or long-lasting mil-sims. What’s more, the fiberglass

reinforcement makes the receiver also more durable than polymer and metal receivers. 

The replica features an ESA™ Quick Spring Change 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.

The gearbox contains 8 mm slide bearings as well as shimmed steel gears based on them.

The system is secured with four anti-reversal latches. A light, made of polycarbonate polymer piston

is equipped with a full steel strip, in order to increase its durability. Also, implemented were a type 0

cylinder and a steel circuit-breaker, as well as a precise rotary Hop-Up chamber. 

The durability of parts allows for the cooperation with M140 springs.

A carefully made Rotary Hop-Up chamber splendidly cooperates with a high-quality precision barrel

with a diameter of 6.03 mm. The implementation of a precision barrel increases the replica’s range

and accuracy. One must remember to use high-quality 6 mm BBs. 

The replica is equipped with a long, top rail as well as two M-LOK / RIS 22 mm side rails, QD tactical

sling swivels and an adjustable stock. The top RIS rail features a flip-up rear sight that does not collide

with optoelectronic aiming devices. Due to the extendable stock with an anti-slip stock pad, it is possible

to adapt the replica’s length to the body type and preferences of the User. A standard flash hider is

based on a 14 mm left-handed thread, which allows the attachment of a silencer in its place.

The set includes an S-MAG Hi-Cap magazine with a capacity of up to 380 BBs. S-MAG is an exclusive

polymer magazine designed by Specna Arms. Noteworthy is the characteristic texture comprised of 

Specna Arms logos. S-mag facilitates a seamless feeding of BBs even at high ROF.

The set includes:

- replica
- S-Mag magazine
- fixed iron sights
- additional main spring
