Full description


Based on a rugged military design which has seen service with the United States Marine Corps since 2001, the ASG M40A3 is a 1:1 scale spring powered bolt action Airsoft sniper rifle, and is fully licensed and trademarked by McMillan Firearms.

Just like the real M40A3, this quality Airsoft replica from ASG features dual alloy and polymer construction. Authentic to the real design, the Airsoft M40A3 uses a lightweight and durable polymer stock, which holds the alloy barrel, receiver and bolt. The bolt is an easy to use design, allowing for fast and smooth re-cocking for quick follow-up shots. To top it all off, the replica features fully licenced and accurate markings and branding from McMillan, making this Airsoft replica almost indistinguishable from the real thing.

A 20mm RIS rail located on the upper face of the receiver allows users to attach a wide range of sights and scopes as they wish. The lower face of the handguard features a short section of 20mm rail, providing ample space to install tactical accessories such as a bipod or foregrip. User comfort can be improved thanks to the stock’s adjustable cheek rest and buttstock. The cheek rest can be raised or lowered without tools, to ensure that users are able to get the best possible eye relief when aiming, whilst the stock’s length can be adjusted to ensure that users can comfortably hold and aim the rifle.

Excellent build quality, brilliant out of the box performance and incredibly realistic, the ASG VFC M40A3 brings a lot to the table! For anyone attempting to create a USMC marksman loadout from 2001-2015, then the ASG M40A3 is both an excellent and accurate choice.
