BOLT
Airsoft B4A1 carbine
replica

The B4A1 carbine airsoft
gun manufactured by the Taiwanese BOLT Airsoft company is undoubtedly a huge step forward in the evolution of
AEG replicas. Thanks to the application of innovative
solutions, ??it finally became possible to eventually approximate the experience felt
by an AEG replica user to those that are offered by a GBBR type replica – that
is, in a nutshell, the BOLT Airsoft company has created a carbine replica that
really “kicks” as it should.

The airsoft gun is made from high quality materials
and with the utmost attention to details. All metal components were made
from T6 aluminum alloy, which is
characterized by very high durability,
similar to that of some steel alloys. These properties were achieved thanks to saturation
and the aging of the material. What is worth mentioning, T6 aluminum alloy corrosion
occurs only in contact with strong acids – this provides a significant resistance of the airsoft gun to the typical weather
conditions found on the airsoft battlefield. 

The fitting of elements does not raise any
objections. There is no backlash even between the upper and lower half of the
body, which frequently is a quite characteristic and often occurring flaw of
other models, even those of well-known manufacturers. Providing the airsoft gun with
diversified colouring is also an interesting procedure. Instead of a deep black, which
is often found in various airsoft guns, here we have several shades of black
and steel colour of the barrel and many other small elements. This
allows to give the airsoft gun a more realistic look, which is much more closer
to the real steel version. This effect is further intensified by the use of
special paint to cover the airsoft gun, which gives it the effect that the
surface has a slightly grainy texture.

The airsoft gun is provided with a multi-position
buttstock and a carry handle mounted on the RIS rail. Once we dismount the
abovementioned handle, we are able to attach any given type of optical sights, e.g. red dots or tactical scopes.

As regards the quality of internal components, it
is very important to emphasize the fact that the gearbox construction used in
the airsoft gun is based on the components
manufactured by another well-known Taiwanese company – LCT. The
products of the LCT company are known for their durability and reliability, which in return guarantees long and trouble-free
operation of the set. The gearbox is equipped with a metal cylinder head,
a metal piston head, and a sealed nozzle. The whole operates perfectly
with the M120 nonlinear spring.

Undoubtedly, the greatest advantage of this airsoft
gun is the system that simulates the recoil and lock operation. This
system consists of two independent elements: a standard mechanism that
imitates the operation of the lock, which can be found in most EBB airsoft guns
and a separate system mounted inside the stock tube. The latter consists of a
spring, an inertia element and a unit which transfers the energy of the piston
onto the inertia element. The experience
offered by the application of this system cannot be compared with anything
previously offered by the manufacturers of serial AEG replicas. The
unit is provided in a separate box; not mounted in the airsoft gun – the B4A1 can
also operate without it.

A further significant fact is that, despite some
structural differences enforced by the use of the Blow Back system, the airsoft
gun is largely compatible with the  v.2 standard established by TM. In fact, the only significant difference is the
piston with a characteristic notch. However, the piston is equipped with a set of metal teeth, which guarantees high
durability of the element. The fact that the other gearbox parts are
compatible with the standard ones ensures easy tuning of the airsoft gun, as
well as easy access to spare and service parts if needed.

Another equally important aspect is the fact that
the replica uses standard magazines
modeled on the STANAG standard – therefore, it does not require the purchase of
specialized and expensive magazines; B4A1 works seamlessly with magazines made
by popular companies, such as Boyi or JG.
