B4 DEVGRU High Cycle carbine
replica by Taiwanese BOLT
Airsoft is a replica made from high-quality materials with the utmost
care for details. All metal elements were made of aluminum.
Furthermore, some elements were made of steel. These include: the flash
hider, magazine and stock mounting ring. The alignment of elements is not a
subject of any concern. There are no loose spots, especially
between the upper and lower receivers, which is characteristic for “top shelf”
replicas. An interesting solution is also the inconsistent paint job of the
replica. Instead of a deep black color often seen in replicas, here we have
different shades of black and a barrel and many other small elements in a steel
color. This allowed bringing the appearance of the replica closer to that of
the original, giving it a more realistic look. This effect is further
reinforced by the use of a paint that gives the surface a grainy texture.
The replica features a multi-position,
telescopic SF stock - featuring a thick, rubber stock pad and sockets
for the attachment of a QD tactical sling. The top of the receiver features a
RIS 22 mm rail with metal iron sights attached. The handguard
of the replica features 4 RIS 22 mm rails that allow for the attachment of
various additional accessories such as tactical flashlights, red dot sights or
laser sights. The replica has a finish in the form of a fully-steel flash
hider. The replica comes with a steel Hi-Cap magazine with a
capacity of up to 300 BBs as well as a polymer grip that improves
the handling of the replica.
The biggest asset of the replica is the
Electric Blow Back (EBB) that simulates the operation of the bolt. An
important fact is that due to certain construction differences resulting from
the implementation of Blow Back system, the replica is to a large degree
compliant with the V.2 standard set by TM. The only important difference is the
piston with a characteristic notch. It is, however, equipped with an array of
metal teeth, which guarantees a significant durability. The compatibility of
remaining parts of the gearbox guarantees an easy tuning as well the access to
spare and maintenance parts if needed. A high-quality Hop-Up chamber
in combination with a 6.01 mm precision barrel guarantees an excellent
performance.
Attention: The set does not
include a battery or a charger.
The set includes:
- replica

- User’s manuals
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).
