Full description


This is an absolutely rock solid full-length SPR platform weapon with an almost exclusively Alloy exterior, with a Nylon fiber reinforced pistol grip & stock - leaving you with a creak and wobble free platform to start a long range build, or just run something slightly different. The metal on the exterior has been through an anodising process and is powder coated to give you not only a great feeling finish, but an incredibly strong and sturdy material to add your accessories. The front of the weapon features a 29cm full length RIS rail which will let you attach your 20mm accessories straight out of the box. There is also a 20mm rail atop the receiver for the attachment of all manner of optics and sights, long range or short. The length of the barrel is a great starting point for a DMR build should you wish to reach out further than others on the field, but will make an equally acceptable full-auto Assault Rifle for getting close and personal. The flip-up iron sights come pre installed and can be adjusted to account for windage and elevation. The solid stock is a comfortable length, and gives you more battery space than most stocks on the market can offer, meaning more time in the field playing and less time in the safe zone changing batteries. For maximum life, we recommend a LiPo or NIMH block battery. The receiver features some lovely markings and the mock bolt cover will lock to the rear, with a functional bolt release to send it home when you're finished adjusting the HOP. The enter & convert quick change spring system couldn't be easier to use, and although isn't as quick as other guns in this series, means you don't have to disassemble the gearbox to change the output power of the weapon.
