MK18 SA-A03 ONE SAEC SYSTEM BK / TAN SECNA ARMS SPEARGUN (SPE-01-009315)

Specna Arms' SA-A03 assault rifle replica is made largely of an alloy of zinc and aluminum, with the use of steel elements in the most vulnerable points of the replica (steel elements: all screws, harness pins and tactical swivels). The SF stock and pistol grip are made of polymer plastic. The replica body and RIS track set have been anodized , which ensures a high level of corrosion protection. The painting of the replica itself was done by pulverizing , after the surface was sandblasted. This guarantees a much higher than normal abrasion resistance of the applied paint.
The replica uses a new generation quick-change spring system, the so-called SAEC ™ . It allows for a quick and efficient change of replica power under conditions expected in the field of play without the need to have access to a workshop or a set of specialized tools. The spring replacement process is now even faster than the previous version of the system.

Thanks to the SAEC ™ System , there is no need to remove the gearbox from the replica
By removing the stock tube, simply unscrewing the fixing ring nut by hand, we will access the SAEC system, an extractable spring guide screwed to the replica body.
Unscrewing the system we will access the inside of the gearbox leaving the replica intact.

The benefits of the SAEC ™ system are hard to overestimate. In light of the prevailing trend across Europe to apply legal limits to the initial speed of replication and to existing arrangements within the environments themselves, this system offers the user considerable opportunities and a lot of freedom. The SAEC ™ System allows you to replace the main spring with a minimum of time , and then adjust the initial speed of the replica to the playing area in order to guarantee an ideal compromise between the effectiveness of the fire and the safety of yours and the players. other players.

The replica has been fully adapted to work with LiPo and LiFe batteries. Thanks to the initial muzzle velocity of ~ 430 FPS guaranteed by the factory installed mainspring, the replica is perfect for medium range operations. The set also includes an M90 type spring , which allows the initial speed to be reduced to ~ 310 FPS, thus making the replica perfectly suited to operate over short distances or inside buildings.
The gearbox, reinforced at the height of the cylinder head, hides a steel spring guide, which is an element of the SAEC ™ System, and steel gears mounted on 8 mm ball bearings . A lightweight piston, made of polycarbonate plastic, is equipped with a series of steel teeth to increase its durability.
  The replica is factory equipped with an accurate polymer rotating hop-up chamber, which allows a very precise and stable adjustment of the BB rotation system .  

The Updated version has a number of new reinforced parts such as:
a series of reinforced steel gears
a steel spring guide with ball bearings
a light polymer piston with a steel teeth
an aluminum sealed piston head
a metal cylinder head
a metal nozzle

The replica is equipped with a 22mm RIS and an adjustable stock. The flip-up metal sights are mounted on the top RIS rail, but can easily be replaced by any front sight. Thanks to the retractable stock with a non-slip texture, it is possible to adapt the length of the replica to the body type and preferences of the shooter. The standard flash hider is mounted on a 14 mm left-hand thread , which allows the attachment of a silencer in its place.
To increase the realism of the game, the replica was also equipped with a working Bolt catch
