Action Sport Games (ASG) was founded in 2003 and is a Danish company that is widely known for its replica firearms. ASG offers a huge selection of Airsoft guns, air guns, BBs, and pellet guns. They hold numerous licenses from real firearm manufacturers and produce quality licensed replicas from companies such as McMillan in the case of the M40A3 Sniper Rifle we are looking at.
Action Sport Games released the M40A3 sniper rifle, a welcomed addition to the sniper rifles on the market. The M40A3 is our favorite spring-powered sniper rifle, and for good reason. It's perfect for any airsoft test sniper looking for precision and reliability.

The ASG M40A3 features a licensed McMillan A4 stock. McMillan is well known for building some of the finest rifle chassis on the market. The rifle has a phenomenal trigger pull out of the box and boasts substantial power in stock configuration. There are factory upgradable parts offered by ASG, which not only improve the power and trigger pull but also the reliability of the trigger and piston components.
The rifle has a textured vertical grip with enlarged palm swell to give the shooter a comfortable, accurate grip on the gun. The square, textured fore-end is perfect for resting on a bag in a supported firing position. ASG also included a picatinny rail with elevation built into the scope base, which should compliment long-range work with the trajectory of an airsoft gun.
McMillan A4 stock also comes with an adjustable cheek rest, which is perfect for fitting all types of optics and is mandatory to achieve a perfect cheek weld.
Action Sport Games also has a front picatinny rail system, perfect for mounting numerous accessories such as IR illuminators, lasers, and passive thermal and night vision optics.
ASG's McMillan M40A3 is a faithful replica of the United States Marine Corps M40A3 Sniper Rifle. It is beautifully crafted by Vega Force Company of Taiwan and is extremely high quality. The gun comes out of the box, shooting approximately 450 FPS with a .20-gram BB. There are numerous accessories for the rifle offered by ASG to simplify the upgrade mystery that plagues most sniper rifles. Typical problems like trying to fit aftermarket sniper rifle parts made for Tokyo Marui VSR-10 or Maruzen APS2 guns into China BAR-10 or L96 clones and having slight compatibility issues are a thing of the past.
With all the upgrade kit, tight bore barrel offered by ASG, and some secret Fox Custom modifications to the rifle, we have seen approximately 600 FPS with a .20G BB. We would be using a heavier BB for actual gameplay, but for velocity testing purposes, we are using a .20G BB as the standard.
A “Zero Trigger” is available for the rifle from ASG, will handle the upgraded spring from Action Sport Games, and will provide a phenomenally crisp, clean trigger pull.
Overall, we give this a solid 9 out of 10 rating for sniper rifles.
