We think that this is a price adjustment, rather than a limited price drop on Gunfire Poland's ASCU, so more affordable now to those who want to use a MOSFET on their AEGs... "The patented, two-piece ACSU - Airsoft Smart Control Unit  - is an advanced optoelectronic system controlled by a processor, designed specifically to control the work of gearboxes in AEG replicas.

The control unit is very small and can be placed in the buttstock of the gun (the unit's size is 6.5 cm x 1.6 cm x 1.4 cm), while the second part (the sensory unit) is ment to replace the contacts among with the wiring.

The Sensory Unit monitors the work of the piston rack and thus the whole system is able to perform a complete cycle each time - the BB will never stay in the barrel after the magazine is taken out and the piston and spring will never stay in the back position.

The ASCU module is designed to work with further sensors, which will not permit you to shoot when the magazine is empty, and if an "M" type gun is used, will force the user to use the bolt catch after exchanging the magazine to a new one.

The unit speeds up the reaction of the AEG replica to the trigger,  making it virtually instantaneous in comparison with other, classical systems.

Prevents accidental double shots: when re-pressing the trigger is faster than human reaction time, each pull on the trigger results in one shot placed.

Allows you to shoot in 'burst' mode by a short pull on the trigger while in 'auto' mode.

An easy mounting system replaces the contacts and the antireversal at any V2 gearbox, which allows to prevent  jamming of the piston, and gives a guarantee that whenever the replica shoots, it performs a complete cycle.

The ASCU controls the battery charge level and prevents an excessive discharge, which is very important when using lithium batteries (LiPo, LiIon, LiFe).

The module detects problems and defects by emitting a sound and vibration and cutting off the power, thus not allowing more more damage to the GB.

The ASCU lenghtens the battery's durability.

It gives more possibilities than Systema  Revolution and PTW  at a much lower installation cost and allows the use of a wide range of spare parts available for the standard V.2 gearboxes.

The product is sold with a 24-month warranty, but only when it is  installed by an authorized service center."
