SA-B15 KeyMod 14” Carbine Replica

SA-B15 by Specna Arms was mostly made from an alloy of zinc and aluminum with several steel elements placed in the most troublesome spots of the replica (pins, screws and tactical sling swivels). The SF type stock, which stores a battery, as well as the pistol grip were made from polymer. The body of the replica has undergone a process of anodizing, which guarantees a high level of protection against corrosion. The paint job was conducted by powder coating, after the surface has been sandblasted beforehand. Such a way of applying the paint provides a higher than usual paint resistance against abrasion. The body bears USMC markings.

All parts of the replica fit very well together – a standard so high that so far it could only be observed solely in replicas from such well-known brands as G&P or Classic Army – and it is exceptionally well balanced. All that makes this replica highly maneuverable and its weight is practically imperceptible when put against the shoulder.

Features a fast spring release system, so-called Enter & Convert™. It allows for rapid and seamless adjustment of spring’s strength to expected conditions on simulated battlefield without a workshop nearby or access to special tools – once the gearbox has been removed from the body, the process of changing the spring takes mere seconds.

Advantages of Enter & Convert™ cannot be overestimated. In the light of currently reigning policy in Europe to adhere to law enforced restrictions on muzzle velocity of the replica and regulations concerning the environment itself, this system guarantees the user wide possibilities and a lot of freedom. Enter & Cover™ system allows with minimal amount of time to exchange the main spring, as a result, to adjust muzzle velocity of the replica to the battlefield area so that the best compromise between fire efficiency and safety of the user as well as other players is struck.

The replica is fully compatible with LiPo and LiFe batteries. Stock muzzle velocity of ~420 FPS is guaranteed by the default main spring, which allows this replica to perform well on medium distance. The set includes a M90 spring, which allows to reduce the muzzle velocity to ~320 FPS, thus adapting the replica to use in close quarters and indoors.

The gearbox which is reinforced on the height of the cylinder’s head hides a steel main spring guide which is the element of the Enter & Convert™ system and also 8mm ball bearings and steel thread-wheels which are placed on spacers. The system is secured with the use of four anti-reversals. There is a type 2 cylinder and the steel breaker and a metal hop-up chamber applied in this replica.

The Upgraded Version is equipped with some new, improved internal parts:

- set of reinforced steel gears
- steel spring guide
- lightweight, polymer piston
- aluminum, sealed piston head
- metal cylinder head
- air seal metal nozzle

The replica has a top, 22mm, RIS rail and an adjustable stock. The top RIS rail features flip-up iron sights, which can be easily detached and replaced with any optical sight. A collapsible stock with an anti-slip texture stockpad allows the user to adjust the length of the replica to his/her body type and preferences. A standard flash hider is mounted on a 14mm, left-hand thread, which allows for its replacement with a silencer.

This model features a 14”, modular, KeyMod handguard. The KeyMod module can be expanded upon with dedicated segments, for instance, RIS rails (KeyMod nuts) in any position or configuration due to holes around the handguard (KeyMod slots).

It is an airsoft replica of a KeyMod handguard, its size may vary from original. We do not guarantee full compatibility of KeyMod handguard with dedicated KeyMod accessories.

In order to increase the realism, the replica has an operational bolt release mechanism.

The replica comes with a steel, hi-cap magazine with a capacity of up to 300 BBs. The magazine’s paint colour corresponds to the colour theme of magazine for live firearms usually used by military.

Specna Arms replicas are compatible with most of the magazines available in the market, for instance with magazines of the following manufacturers:
 - BOYI,
 - Airsoft Systems,
 - SRC,
 - King Arms,

I have just ordered this weapon. The set of KeyMod RIS rails was installed at the beginning of the handguard to the left and right side and one to the bottom. There was 6 certificated test shot with an avarage 445 fps with 0.20g BB and without any hop-up effect. The weapon looks awesome and you feel that it is really massive. I recommend this weapon. Everything was satisfied with the shipping the payments and with the support team. I also ordered some external parts and fits perfectly.
