Full description


Specna Arms have made a name for themselves by producing Airsoft replicas with stunning external build quality, coupled with top-shelf internals and attractively priced to make high performance affordable for all Airsofters. In an interesting turn of events, they have now turned their sights to the Bolt Action Sniper Rifle market, creating the SA-S03 M40A5.

The Sniper Rifle is built to an amazing standard as you would expect, using N-Core reinforced Polymers to create a body which is bulky and satisfying to shoulder, tough enough to go the extra mile and yet still lightweight enough to make this a manageable rifle. The upper receiver and all external trim components such as the cheek rest and trigger well are made from Alloy with a Nano Coating finish that protects the metalwork from scratches. The rifle comes included with a Polymer 20mm rail piece for the handguard, which allows you to attach laser/light accessories and requires fixing to the body via self-tapping screws. The upper receiver also features an Alloy 20mm rail which is ready for the included scope or any other optics you may have lying about. Just to the right of the bolt handle you will find the safety lever, which blocks off the trigger from use  when it is in the rear position. The HOP adjust can be found along the side of the handguard when the rifle is fully built, and is an easy to use slider adjust which simply needs pushing backwards/forwards to use. We recommend the use of a heavyweight BB (0.3g+) and the perfect setting of the HOP unit to get the most out of this rifle. The adjustable cheek rest at the back is perfect for those who want to be able to return to the same position on the scope every time for accurate, consistent shots, and the adjustable stock length means you can get it feeling just right, no matter your size. There are QD sling sockets on the front and rear of the stock, allowing you to create some interesting sling setups. Included in the box are three 20rnd magazines, tools for assembly and the 20mm rail piece, which is more than enough to get you on your way to taking names in the battlefield.

If you're looking for a sniper rifle which is built to a crazy high standard, has everything you need to go right out of the box, has smooth and consistent performance without too much setup, and is reasonably priced, the SA-S03 M40A5 is just the ticket.
