APS BOAR Competition M4 SDU Gelsoft Blaster - BKMC

SKU: g2e118BKMC


There is no doubt that the AR-15 or M4 are the most popular and used rifles among gelsoft players. And it's not surprising to see how many M4s are used in an assortment of gameplay styles. Although hundreds of variations of this model exist, APS has created a fantastic series of gel blaster rifles that can stand out on the battlefield.

This particular gel blaster model is the BOAR Competition in Black Multicam. The Boar Competition features the eSilverEdge gearbox, full metal construction (including receiver), massive 16" Keymod Handguard, gold highlighted external components, a beautiful black Multicam finish & 280+ FPS on 7.4v battery. 

Do not upgrade any part of your toy gel blaster as this will void the warranty. Upgrades refer to pulling any of the blaster apart or opening it up, changing springs or upgrading the battery from 7.4v to an 11.v battery.  The scope on one of the photos is not included as part of the blaster.

Use of Advanced S.D.U.™ chips

The S.D.U. chipset that used in eSilver Edge Gear Box has a unique function that stop the gearbox from further damage if electric current is too high. Simply to say, electric current / Ampere will increase if there is a malfunction inside the gearbox. For instant, bad motor, damaged gears or short circuit. When our S.D.U. detected more than 5 trigger presses in exceed Amps, the whole gearbox will shut down to prevent further damage. User has to disconnect and then reconnect the power supply to reboot the gearbox, we strongly recommended user to check the internal immediately if mal-function happened.

Micro Switch Trigger

eSilver Edge Gear Box standard comes with micro switch trigger works together with the S.D.U.,  providing you an instant trigger response when shooting. Base on our testing, the response time of the switch is just 0.02 sec and designed for two hundred thousand press. With the short stroke design of the trigger, it is unbelievable fast and you won’t feel any trigger delay when shooting.
