AR4-SBR ECS Carbine Replica
A highest-quality AR4-SBR ECS carbine
replica by Classic Army is an excellent proposition for any CQB skirmish
enthusiast due to its compact size.
The replica was made mainly of durable
polymer. This allowed to reduce the weight of the entire construction whilst at
the same time providing an excellent alignment of parts and maintaining the
adequate durability.
The replica features a short RIS rail with an
MLOK mounting system. The top RIS rail features flip-up iron sights. The
foldable, two-setting stock enables the adaptation of the length of the replica
to a User and makes it a compact construction, ideal for CQB scenarios.
The battery container is located under the
stock of the replica - access to the storage is protected by a special overlay
screwed with a hex screw.
The heart of the replica consists of a
reinforced gearbox with 9 mm bearings, low-resistance cables and
steel gears in a 21:1 ratio. The entirety is crowned with a quick spring change
system and an ECU (Electronic Control Unit) with the possibility of
programming the trigger.
The implementation of a 6.03 mm precision
barrel enables the achieving of excellent performance straight out of the box.
The set includes a magazine with a capacity of approximately 250 BBs.
The set does not include a battery or a
charger.
The set includes:
- replica
- magazine
- cleaning rod
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).
