B4 M16A4 (B.R.S.S.) Carbine
Replica
B4 M16A4 carbine replica
by Taiwanese BOLT Airsoft company is undoubtedly a significant
step forward in the evolution of AEG replicas. Due to
implemented innovative solutions, it was finally possible to mimic
the experience of using a GBBR type replica in an AEG type replica. In short,
BOLT Airsoft was able to create an assault rifle replica that truly has a
“kick” that it should have.
The replica was 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.
The top of the replica as well as
the handguard have RIS 22 mm rails that allow for the attachment of additional
accessories such as red dot sights, scopes or tactical flashlights. The pistol
grip was made of polymer. The replica has a finish in the form of a steel flash
hider. The replica comes with a Hi-Cap magazine with a capacity of up to 300
BBs.
The greatest asset of this
replica is undoubtedly the recoil and bolt operation simulation system.
It consists of two independent elements: a standard bolt operation imitation
known from a majority of EBB replicas and a separate system installed inside
the buffer tube. This system consists of springs, an inertia element and a
system that transfers the energy from the piston to the inertia element.
The experience offered by the implementation of this solution cannot be
compared with anything else offered so far by other serial manufacturers of AEG
replicas. 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
- magazine
- external barrel extension
- BOLT Airsoft collector patch

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).
