RRA SA-C05 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 exchange 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, the RIS handguard, the silencer, the enlarged
charging handle and tactical sling
swivels were made of metal (parts made of steel include screws, pins, the shell
ejection window and the 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 replica is fully compatible with LiPo and LiFe batteries. Due to a base muzzle velocity of ~380
FPS provided by the main spring installed by default by the
manufacturer, the replica is perfect for operating on a medium range. The set
also includes an M90 spring, which allows reducing the muzzle
velocity to ~310 FPS and as a result to adapt the replica for
close-ranged and indoor operations.

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 1
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 22 mm top RIS rail, RIS handguard and an adjustable stock. The top RIS rail
features flip-up iron sights that do 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. The silencer is based on a 14 mm left-handed thread.

The set includes: 

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