SA-H20 EDGE 2.0™ Carbine Replica

The EDGE 2.0 ™ series introduces a completely new quality to
the Specna Arms replicas family by adding new functionalities and
innovations to the standard already proven by airsoft players. As a
result, Specna Arms EDGE 2.0 ™ carbines offer an exceptional level of
quality and technical advancement straight out of the box.

What distinguishes EDGE 2.0 ™ from the previous version?

– Solar™ Trigger
– Helium™ Flat Hop Bucking
– High Torque Motor
– ESA2™ Quick Spring Change System

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 Specna 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 easy and rapid access to the motor without having to use tools
as well as a double-sided loop for the attachment of a tactical sling.

SA-H20 carbine replica is equipped with a handguard in RIS / Picatinny mounting
system that can serve as a mount for various tactical accessories:
flashlights, grips, laser sights and optical sights. The barrel features
a muzzle device on a 14 mm CCW thread. The top RIS rail features the
set of iron sights.

The replica features an internal precision barrel with 6.03 mm in diameter that provides high accuracy and repeatability of fired shots with a new type of a Hop-Up rotary chamber.

Preinstalled Helium™ Flat Hop bucking allows for a very precise and stable adjustment of the BB spin.

The replica features an ESA2™ Quick Spring Exchange 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.

advantages of the ESA2™ 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.
ESA2™ 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.

ESA2™ system is included in the European Patent with a number: 007422159-0001

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 arrays 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
– lightweight, polymer double air-sealed piston head with bearings
– aluminum, air-sealed nozzle
– aluminum, double air-sealed cylinder head
– bearing-mounted spring slide
– set of steel gears
– 8 mm ball bearings

The replica uses a powerful and efficient High Torque motor equipped with powerful neodymium magnets. The motor has 22TPA (Turn Per Arm) winding and can handle without issue springs more powerful than the one included in the set.

system is the younger brother of a well-known TITAN™ unit. This fourth
generation of AEG control systems was designed with a majority of
electric replicas equipped with gearbox V2 in mind, also those that
undergo demanding tuning. ASTER™ allows to reach maximum durability whilst retaining the attractive price. This system is characteristic for its uniquely beneficial price to efficiency ratio.

Thanks to ASTER™, you can improve your replica by replacing the connectors with an advanced controller equipped with innovative optical sensors,
which offers up to 240 trigger sensitivity settings. Trigger rapid
reaction and many other useful functions will enable you to get an edge
over opponents on the airsoft battlefield. An intelligent fuse protects
the battery, the motor and the controller, even from a reverse
connection of the battery. This function, along with optical sensors,
makes ASTER™ the most durable drop-in type system available on the

ASTER™ provides new possibilities:

– safeguard from reverse polarization of a battery
– innovative optical sensors
– 250 trigger sensitivity settings
– ability to configure with the use of the replica’s trigger or GATE Control Station application
– integrated RGB LED diode simplifying the programming of the system
– premium functionality at a reasonable price

The EDGE 2.0™ replicas are equipped with a dedicated Solar™ Trigger, which works perfectly with the ASTER™ sensors,
offering unprecedented sensitivity and precision. The new Specna Arms
trigger is made under license of Gate Quantum Trigger™.

functions of ASTER system are available in GCS (Gate Control Station).

A valid defence is required to purchase any Airsoft Replica Firearm. If you don’t have a defence you must add Two Tone to your basket.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

To purchase a realistically coloured Airsoft Replica Firearm (RIF) you must have a valid defence.  The most common of these is UKARA which stands for United Kingdom Airsoft Retailers Association and is essentially a database of registered players.  UKARA requires you must be a site member at any of the registered UK Airsoft sites.  This means you must play 3 games in MORE  than 56 Days. Once you become a member you are added to the database, please note paperwork and validation is required.  There are other types of defence, but UKARA is by far the most popular.  Please note this only applies to the gun, not the kit or accessories.

If you don’t yet have a defence, you can always add two-tone to your order. This simply means you have 51% painted in a bright colour such as green, blue or orange.  You can then purchase any RIF you wish.

If you have any questions regarding what is or isn’t a defence, or just looking for some general airsoft advice, then please drop us a call or contact us here
