SW-20BM Carbine Replica
Firearms in a bull-pup system (sometimes referred to as stockless) have a long tradition and an equal amount of enthusiasts as well as skeptics. One of the advantages of this construction can be hardly ignored - it is the possibility of the implementation of a really long and effective barrel, whilst maintaining a relatively compact size of the firearm. It is important to note the aesthetic value as well - bull-pup firearms are simply unique and they cannot be mistaken for anything else.
Similarly to the live firearm, the receiver of the replica was made of durable polymer. Metal parts include: the entire front of the replica with the external barrel, top RIS rail and miscellaneous elements such as the shell ejection port cover.
The rear as well as the front part of the replica feature tactical sling swivels. Access to the Hop-Up adjustment knob is gained in a traditional way - after pulling back the charging handle and uncovering the shell ejection port. The handle can be locked in a rear position. What is characteristic for this construction is that shell ejection ports are located on both sides of the receiver, which makes it comfortable to use for a left-handed User as well.
The battery of the replica is stored inside the stock (if one can use such a word in the case of a stockless design). In order to access the battery, one needs to remove the rubber stock pad. No tools are necessary for that operation because it is attached by being pressed into its place. The disassembly of the entire replica into two parts also lasts mere seconds. It is necessary to access the Hop-Up chamber and the internal barrel. In order to do that, it is necessary to press a metal pin - a lock - and afterward the fire selector and split away the construction into 2 parts - the receiver and front part with the barrel.
The replica features 4 RIS rails located on top of the replica, on its sides and under the barrel.
The replica features a two-stage trigger, whose first stage causes the replica to fire in a semi mode and a full pull - in a fully automatic mode. The safety is located at the pistol grip and can be operated from both sides. In the front, under the barrel is a characteristic for the rifle, foldable 3-setting vertical forward grip.
The replica has a quick spring change system that allows with a minimal amount of time to change the main spring. There is no need to take out the gearbox and disassemble the entire construction. All that is necessary is to remove the stock pad, unscrew the plastic cap and through the opening in the back side of the gearbox pull out the slide with the spring. The system allows 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. This allows to easily guarantee an ideal compromise between the effectiveness of fire and safety for the user himself as well as other participants.
The replica comes with a polymer Hi-Cap magazine with a capacity of up to 330 BBs.
The set does not include a battery or a charger.
The set includes:
- replica- magazine
- tactical sling
- User’s manual
- bipod
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
immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the
life - on the other hand, they earn about 30% more capacity.
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.
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.
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).
