King Arms M4 TWS M-LOK Rifle Ultra Grade II – Black

The King Arms M4 TWS M-LOK rifle is a good starter gun with a quick change spring, mosfet trigger system and M-LOK hand guard.

The rifle is built from polymer with a metal barrel. The stock has six adjustable positions for different size players and has two QD sling attachment points. The fire selector is located on the left side and has three modes, safe, semi and full auto. The magazine release is on the right side and the folding sights can be adjusted for windage. To access the hop unit you need to pull back the charging handle, which will cause the dust cover to flip open and reveal the hop unit.

There is rail all along the top of the rifle, which gives you a wide array of options for mounting optics and PEQ boxes to. The handguard uses M-LOK and so, is compatible with all M-LOK attachments. The rifle already comes with three pieces of rail so you can attach a foregrip, torch or laser to the rifle. At the end of the barrel is the flash hider, which can be removed to reveal the 14mm CCW thread that can be used to attach a suppressor or tracer unit to.

The rifle’s barrel length means it has good accuracy and will happily cope with ranged firefights. The rifle has a quick change spring system to help for when you need to change the fps easily. It also has a mosfet trigger system, which helps with trigger response.
