B4 PDW S (B.R.S.S.) Carbine

B4 PDW S (B.R.S.S.) 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 a 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. 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 PDW stock – featuring a comfortable cheek pad and
stock pad as well as sockets for the attachment of a QD tactical sling.  The top of the replica has a RIS 22 mm rail
that allows for the attachment of additional accessories. The polymer handguard
of the replica was made in M-LOK mounting system that enables the attachment of
additional accessories. The replica has a finish in the form of a steel
silencer. The replica comes with a Mid-Cap magazine with a capacity of up
to 140 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
guarantees an excellent performance, despite a short barrel – ideal
for CQB.
