RRA SA-C18 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 as well as the
pistol grip were made of nylon-fiber reinforced polymer. Remaining components
such as the barrel, URX 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 change 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 ~330 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 ~260 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 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 22
mm top RIS handguard 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 wires in the replica have
been led to the RIS handguard, where the included in the set PEQ case can be
installed, which is capable of housing a square-shaped battery.
