The replica is made mainly of nylon fibre-reinforced polymer and metal parts. The polymer used is characterised by high strength, rough texture and matt colour.
The most critical parts are made of metal , including: flame suppressor, external barrel, dummy slide, shell ejector flap, fire mode switch, breech release button, magazine clip, QD attachments on the butt, pins and reloading lever.
The barrel is a Specna Arms proprietary design combining aesthetic qualities with high ergonomics. Each element has been manufactured and fitted with attention to detail. The model has enlarged manipulators on both sides (selector and magazine release) and a functional bolt-catch.
The Light Ops Stock is a minimalist stock with low weight and an impeccable and modernistic design. The model has rubber non-slip stickers on both sides of the cheek piece, and a distinctive curved rubber stock foot that settles comfortably on the shoulder.

Battery included![]() 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

Muzzle velocity [FPS]![]() 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 | 390 |
| Fire mode | Full-auto Adjusted burst Semi-auto |
Gearbox version![]() 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. | Gearbox v2 |
Hop-Up![]() 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). | Yes |
