DELTA
AK21 Assault Rifle Replica
A long-awaited
line of replicas by Nuprol that was designing it for the last 3 years. The
result is an impressive series of exceptionally original and carefully selected
models of high quality, characteristic for replicas from a much higher price
range.
Made from aluminium, steel and high quality nylon polymer, the replica
is characteristic for how well its parts fit together and excellent aesthetics
of the craftsmanship. Structurally reinforced nylon used to
manufacture the pistol grip and stock looks very good comparing to other
products from other well-known and prized manufacturers - both visually and
when it comes to durability to mechanical damage. Thanks to the implementation
of QPQ painting technology it is incredibly resistant to scratching and
chipping off.
Aluminium
receiver and handguard were made using CNC technology, which guarantees
that elements will fit well together. The replica is equipped with a 22 mm
top RIS rail and an adjustable, telescopic SF stock. The battery is stored
inside the stock. The RIS rail bears flip-up, adjustable, metal iron sights in
an angled system. Such a solution allows for the attachment of chosen
optoelectronic aiming devices without having to remove the iron sights.
Standard flash hider is based on 14 mm left-hand thread, which allows
the attachment of a silencer in its place. The handguard has a standard
configuration of 4 RIS 22 mm mounting rails that enable the attachment of any
accessories to the replica. Furthermore, the set includes a front grip that
increases stability and ergonomics of the replica.
Elements of the same pneumatic system have also been made with highest care for
details. The replica also features a QD quick spring change system that
will help to adapt its power to the current conditions on the battlefield in
the blink of an eye. A barrel with a diameter of 6.03 mm provides good
cone of fire and repeatability of shots. A one-piece, polymer Hop-Up chamber
is excellent - Hop-Up adjustment is done as in any other replica of the type -
in order to gain access to the adjustment system it is necessary to pull back
the charging handle. An operational bolt-catch is also worthy of note.
The reinforced, metal gearbox conceals steel gears and a piston
with steel teeth. The entire mechanism is powered by a motor with
increased torque. The replica is fully compatible with LiPo and LiFe
batteries and is equipped with a Tamiya small connector.
The set includes a Hi-Cap magazine with a capacity of up to 370 BBs. The
magazine casing was made from steel.
The
set does not include a battery or a charger.
Additional
accessories visible in the preview photographs are not part of the set!
The
set includes:

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).
