SRT-21 Assault Rifle Replica
A family of replicas under SPARTAC banner meets the expectations of airsoft enthusiasts that are looking for good quality at reasonable price. The main endeavour that allowed to reduce the costs was the implementation of good quality polymer instead of metal in the production process of parts. At the same time a full metal gearbox (that provides over 400 FPS at stock!) and good quality mechanical parts used inside make SPARTAC replicas equally efficient on the airsoft battlefield as their more costly counterparts.
Moments after taking the replica out of the box it is possible to notice how carefully all elements fit together - there are no loose spots and even in vulnerable places such as the cradle/handguard - which is a problem for many models. Every SPARTAC comes with a set of essential accessories such as a battery, charger or a tactical sling - the replica is ready for action almost immediately.
Majority of main components of the replica was made from polymer. These include: the receiver, handguard, stock, iron sights, silencer. The outer barrel was made from a ZnAl alloy, while the magazine casing and bolt carrier replica were made from steel. Despite a mostly polymer-focused construction, the user will not experience an unpleasant “squeaky material” known from many “cheap” replicas.
SRT-20 is equipped with a handguard featuring a set of RIS 22 mm mounting rails. They enable the user to attach a wide array of additional accessories such as optical sights, grips or tactical lighting, etc. Furthermore, the replica has a telescopic stock with an adjustable length with an anti-slip stock pad as well as foldable fixed iron sights. The outer barrel has a right-handed, 14 mm thread which boasts a flash hider.
Access to the hop-up adjustment slide is gained in a traditional way - after pulling back the charging handle. On the left side of the receiver are located the safety and fire mode selector. The heart of this replica is a solid, full metal gearbox v.2 equipped with a set of steel gears, bearing mounted spring slide and 7mm bearings, which allow the replica to achieve a muzzle velocity of ~410 FPS straight out of the box.
The replica comes with a hi-cap steel magazine with a capacity of up to 300 BBs. The battery is stored inside the stock.
The set includes:
- charger for the battery
- tactical sling
- cleaning rod

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.

|Diameter of bearings in GB [mm]:|
The length of the replca is measured between the two most distant points of each other. Different models have several of these values, because of its design allows to increase or decrease it length (eg. folding stock or extended flash hider).
|Inner barrel length [mm]:|
This is a value that includes the weight of the replica, magazine and other accessories that are include in set without a battery, charger, cleaning rod, etc., etc.
|Battery Voltage [V]:|
|Battery Capacity [mAh]:|
Battery capacity determines the time, which it accumulated enough energy to work gearbox. The greater capacity, then replica will shoot longer.
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.
|Magazine capacity [pcs]:|
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).
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.
