From Specna Arm's ONE Series we have the SA-B07, a faithful reprensation of the US Militaries M16 A4 Assualt Rifle.
Featuring a 12" RIS/RAS Rail System, Detachable Carry Handle which when removed reveals a 20MM Sight Rail as well as the characterisitc M16 Style fixed stock and controls. Construced of Zinc Aluminium Alloy for the Reciever and other metal parts, and Polymer for the furniture, it has a solid feeling weight and is finished to a good level. Internally it is built on Specna's Version 2 Gearbox with Quick Change Spring and a Polymer Rotary Hop Unit which gives this RIF plenty of scope for upgrade and customisation but is equally just as good out the box.

509MM Inner Barrel
