About the ASG M40A5 Gas Magazine

This magazine is designed to work with the ASG M40A5 Gas Sniper Rifle.

About the ASG M40A5 Gas Sniper Rifle

The M40A5 Gas Sniper Rifle from ASG is a new take on the M40 series rifle, featuring a gas powered bolt and adjustable FPS.

This sniper rifle is OEM'd by VFC in conjunction with ASG. It was designed as a sort of upgrade to the ASG M40A3, as it features the same external design outside of an accurate detachable box magazine, and improved Green Gas powered internals. The nature of gas powered sniper rifles allows for the bolt to be much shorter, which places the magazine in the correct position to be true to the actual M40A5. Because of the similar exterior design, the M40A5 is compatible with the same external upgrades as the M40A3 including rail systems, bipods, slings, and scopes. It also has the same adjustable cheek rest as the M40A3, allowing you to get the cheek weld you want no matter the height or eye relief of your optic. The included magazine is 14 rounds, and more are available for purchase. The Green Gas operation of this rifle means that is has a fully adjustable FPS, all the way up to 450 FPS. Using different types of gas may yield different results, but Green Gas is recommended for both performance and durability. The gas powered system is also much easier to use than a spring sniper rifle, as there's no massive spring to pull back when reloading. This makes cycling the bolt from a prone or other advantageous position far easier.

The ASG M40A5 Gas Sniper Rifle is gun that's packed with features and is sure to satisfy any aspiring airsoft sniper out there.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
