Sold out


The SA-B03 makes an excellent outdoor rifle and is the perfect candidate for conversion into a DMR. The foresight folds neatly into the rail meaning you can fit the sight of your choice without obstruction. The replica’s body has the USMC markings

A battery is included with this rifle.

This beautifully made replica has a metal upper and lower receiver The RIS rail is also made of metal along with the outer barrel and flash hider. The stock consists of a metal buffer tube and plastic outer. The grip is plastic with a metal base plate heat sink.

Internally the gearbox is of exceptional quality with steel gears mounted on 8mm ball races. The gearbox has excellent air seals and can generate over 400fps from an M110 spring. The spring can be changed without splitting the gearbox.

The motor has excellent torque levels and can easily compress an M130 spring but this would raise the fps beyond any UK site limits.

This replica comes with 1 UK legal spring ~310fps
