RRA SA-C11 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.

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.

The receiver, stock slide, handguard and a SF stock that holds the battery, as well as the pistol grip,

were made from fiber-glass reinforced polymer. Remaining components such as the barrel,

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 fit very well together and the User will not experience any loose spots

between the lower and 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, fiberglass reinforcement makes

the receiver also more durable than polymer and metal receivers. 

The replica features a 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 ESA™ system are hard to overstate.

In the light of the 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 change the main spring,

thusly 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 safety for the

User himself as well as other participants.

The replica is fully compatible with LiPo and LiFe batteries. 

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

The system is secured withfour anti-reversal latches. A light, made of a 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.

The precisely-made rotary type Hop-Up chamber perfectly fit with high quality 6,03 precision barrel.

The use of precision barrel has a positive effect on the range and accuracy of the replica. 

The replica is equipped with a 22 mm short top RIS rail and an adjustable stock.

The top RIS rail features a floding rear sight. 

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 silencer is based on 14 mm left-handed thread, which allows the attachment

of a silencer in its place.

The set includes:

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