Perun P90 Smart Mosfet

Perun for P90 replaces the trigger bar and mechanical contacts in your P90 replica and provides lots of useful features.

Magnetic sensors coupled with a magnet installed directly on the trigger, allow you to remove the bar that connects the trigger with the gearbox, making the trigger pull much smoother.

The proprietary cut-off lever (which comes with the mosfet) works with an optical sensor to eliminate all problems with single fire function.

Replicas compatible with this mosfet include models made by: Tokyo Marui, ACM, Asia Tactical, Classic Army, Cybergun, CYMA, J Tactical and JG Works. Please note this mosfet is incompatible with G&G and Krytac P90’s.

Key Features:

Adjustable trigger sensitivity – The trigger can be set to 5 sensitivity levels for both first and second trigger stage, ranging from short pull needed to fire a shot, to a long one. No modification to the trigger or the gearbox is needed, and the trigger sensitivity change is possible even in the field.

Selectable firing modes – User can choose firing modes available after short or long pull of the trigger: SEMI ONLY, BINARY, SEMI-AUTO, SEMI-BURST, BURST-AUTO.

Active brake – Active brake stops the motor after each shot preventing spring compression or in case of replicas with high rate of fire, overspin (double shot problem).

Precocking – Fast trigger response can be a matter of victory or defeat, especially in CQB situations. With precocking enabled, piston will remain in rear position after each shot with the spring already compressed, ensuring that next shot will be fired immediately after you pull the trigger. To release the spring after using precocking, pull the trigger and hold it for 2 seconds, after which a second shot will be fired, this time with no precocking and fully braked.

Binary trigger – Allows for easy double shots in semi-automatic setting. After enabling this mode, if semi-automatic fire is set, shots will be fired not only when the trigger is pulled, but also when it is released.

Rate of fire reduction – Reduce the rate of fire in automatic or burst fire to save ammo or make the replica shoot in a more realistic fashion.

Low battery voltage alarm – Designed for Li-Po and Li-Ion batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off.

DSG – A sector gear detection mode specially designed to work with dual sector gears.

Diagnostic system – Constantly monitors the replica and the mosfet itself. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier.

Electronic fuse – Will save your replica and battery in case of a major malfunction. It will automatically disconnect the battery when a short circuit or blocked motor is detected.

Programming of all the settings is done solely by using a button and multicolour LED diode mounted in the battery compartment and the trigger. This allows you to change the settings in a matter of seconds, even under enemy fire. All settings are set independently for each selector position, so you can program the mosfet exactly the way you want it, for example semi on semi and binary trigger on auto. Perun for P90 works without problems with any battery from, 7 V to 17 V. It can also be used with the most extreme setups.

To buy an airsoft weapon in the UK you must have a valid airsoft defence.

This is not a licence, it is basically just proof that you intend to buy an airsoft weapon for use in airsoft.

An airsoft defence could be a UKARA or membership with the British Airsoft Club, and various other forms of defence.

You can only obtain an airsoft defence once you are over the age of 18.

To get an airsoft defence the law is that you should play at least 3 games of airsoft, and that you must have been playing for at least two months.

You can still buy an airsoft gun without a defence, provided you are 18 or older. If you choose to do this we would, by law, two tone (paint in a bright colour) parts of your chosen weapon. This is because an airsoft gun is considered a RIF aka Realistic Imitation Firearm, because they are so close to the real steel, whereas when you paint parts of it in a bright colour it becomes an IF aka Imitation Firearm. The reason being that the bright colours make it look less realistic to the public, and therefor less likely to be mistaken as real, were it to be used for any other purpose than airsoft.

When you order a gun from us you will need to add your defence details in the comments section of the cart. If you do not have a defence you will need to write the colour that you wish to be used for two toning your airsoft weapon.

Here is what's stated in the VCRA (Violent Crime Reduction) Act:

For airsoft skirmishing, the Association of British Airsoft is putting in place arrangements to allow retailers to check that individual purchasers are members of a genuine skirmishing club or site. The key elements of these arrangements are:
1. new players must play at least 3 (three) times in a period of not less than two months before being offered membership
2. membership cards with a photograph and recognised format will be issued for production to retailers
3. A central database will be set up for retailers to cross-check a purchaser’s details
4. member’s entry on the database will be deleted if unused for 12 months.
The defence for airsoft skirmishing can apply to individual players because their purchase of realistic imitation firearms for this purpose is considered part of the “holding” of a skirmishing event.
