RRA SA-E18 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
an easy and rapid access to the motor without having to use tools as well as a
double-sided tactical sling swivel.
SA-E18 carbine replica is equipped with a
short handguard in RIS 22 mm mounting system that can serve as a mount
for various tactical accessories: flashlights, grips, laser sights and optical
sights. The replica in its ultra-short version does not feature a standard
stock, instead just a cap. The cables are led to the front of the
replica, which enables concealing the batter in a PEQ case replica included
in the set. The top of the replica features foldable iron
sights.
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
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. 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 array of high-grade parts right
out of the box, which makes it characteristic for its reliability and preparedness
for further tuning. ORION gearbox is ready for cooperation with M140
springs. Inside, there are elements such as:
- reinforced polymer piston with a full,
steel jaw
- aluminum, air-sealed nozzle
- aluminum, double air-sealed cylinder head
- aluminum, double air-sealed piston head with bearings
- bearing-mounted spring slide
- set of steel gears
- 8 mm ball bearings
The box, apart from the replica, includes two
Mid-Cap S-MAG magazines with a capacity of 125 BBs each. 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 does not include a battery or a
charger.
The set includes:
- replica
- 2 x S-MAG Mid-Cap magazine
- additional M90 main spring
- User’s manual
- certificate
- GATE X-ASR diagnostics card
- vertical grip
- battery case
NiCd
rechargeable battery is characterized by high efficiency
current-carrying capacity, but there are disruptive effect on memory.
Should be unloaded and loaded in the full cycle, ie, it is recommended
to fully discharge, and after unloading must charge the battery
immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the
life - on the other hand, they earn about 30% more capacity.
Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.
It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).
1 FPS = 0,3 m/s
1 J = 99 m/s
1 J = 326,7 FPS
Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3.
Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).
