Featuring a custom stock with both upper and lower 20mm RIS accessory rails, the MB03A is WELL's unique version of the ever-popular VSR / BAR 10 bolt action Airsoft sniper rifle, and is perfect for those looking to get started in Airsoft sniping.

Full description


The MB03A is predominantly constructed from alloy, with alloy receiver, barrel assembly and internals, and the stock constructed of lightweight polymer. The rifle features a selection of 20mm RIS rails allowing the attachment of aftermarket parts and accessories, with a top 13.5cm rail for attaching sights and scopes, along with a front bottom 6cm long rail for attaching bipods and other accessories as required by the user. The weapon comes supplied in two sections, the upper assembly which includes the reciever and barrel, and the stock. Users can quickly and easily assemble the two halves using the tools provided by simply slotting them together and screwing in the two retention screws. The front of the barrel features a removable muzzle end cap, which allows the attachment of a thread adaptor for attaching silencers and suppressors. The weapon features an adjustable hop-up system, which is designed to add spin to the BBs, and can be adjusted via an external lever on the underside of the weapon, making it easy to adjust on the fly. The Hop-Up adds spin using a small patch of rubber before the barrel, which stabilises the BB, enhancing its range and accuracy. The lightweight polymer stock is unique to the MB03A, featuring subtle differences to the orignal VSR / BAR 10 design. The rear of the stock features a rubberised butt plate to improve the point of contact between the user and the weapon, ensuring that you have a steady and firm grip on the weapon. The trigger guard is a large design, perfectly suited for users wearing bulky gloves in winter. This rifle is perfect for those who are looking for a great entry level sniper rifle, or for those who want a base for a project weapon.
