Our Analysis, Comparisons & Test Results

ASG m40a3

By taking this rifle down to the last bolt and screw, we’re able to find how it holds up against other airsoft rifles within its budgetary category.

Guess what?

We were super impressed!

With the right BBs, you’ll see it performing quite well, achieving some alarming accuracy and range without trouble.

Besides being easy to use, it comes with an adjustable hop-up, adjustable cheek rest, sturdy barrels, fine trigger pull and more, to make sniping your favorite thing on the field.

While it might be a little heavy, it’s not OTT to handle, especially since its cheek rest and foldable stock make it easy to shoulder.

If you’re looking for a well-balanced rifle that’s easy to use, and gives an absolute feel of a real gun, this is the one for you.

Performance Comparison

1. Value for Money

Most of the best airsoft rifles come at a higher price than the m40a3’s. With a low budget, you’ll get a top-notch quality sniper rifle.

The ASG M40a3 Sportline is a combination of strong metal and durable polymer that will chug on even in the toughest combats.

But wait- there’s more…

This rifle doesn’t only look and feel like the real one the United States Marine Corps uses, it is durable. The Sportline comes with a lightweight polymer stock, making it easier to maneuver and aim at targets.

Also, the magazine capacity is 27 rounds, meaning that you don’t have to keep reloading. And even when you make reloads, it is swift, using the speedloader.

Plus, you can easily engage the adjustable hop-up based on how far away your target is.

From my experience…

..it would have been great if the package included products like the scope and bipod and other optical devices for aiming. They would have helped with precision, support, and accuracy. 

But at the end of the day, you can always pick those up as an add-on.

You’ll still get a realistic gun with the accuracy you need for airsoft battling with the ASG.

2. Power

By now, you should know that this is a powerful sniper rifle. It shoots at great lengths and covers a reasonable range.

Now, here’s how…

When you pull the gun, you’re pulling the spring into a recess. This trigger pull releases the piston and pushes out air locked in the barrel. Like other bolt action rifles, the BB comes flying out. 

For m40a3 sportline sniper rifles, the trigger pull causes BBs to fly at the muzzle velocity of circa 450 fps.

But here’s the thing…

Since the package includes BBs, we tried shooting with the 0.20g BBs when we started testing. It did well, but we wanted more. By moving it up to 0.25g BBs, we achieved more speed and range, as the pellets didn’t go off course.

The hop-up is great for accuracy, but when we tried using .36 BBs, it maxed out. The muzzle velocity reduced to 300 fps, and we covered less range. So we advise that you stick to a BB weight of .20g to 30g if you want your shots to remain powerful.

Some good news?

This rifle is powered by spring, a power source that can’t run out during combat. Also, you won’t need to carry gas canisters or batteries around the field. 

Just fire on, even as others try to fill in some gas or reload batteries.

3. Range

The M40a3 Sportline is suitable for anyone looking to take up the role of a sniper. You’ll enjoy its precision and accuracy levels mostly because of its construction, magazine capacity, and muzzle velocity.

But one thing that struck me about this gun was its range. One time, this rifle hit one of my targets at almost 300 feet!

Here’s the thing…

The rifle operates on a muzzle velocity of 450 fps, and its magazine capacity is a whopping 30 rounds. But that’s not all that determines range.

ASG M40a3 Sportline is designed for super-easy maneuvering with its polymer stock and solid barrel build. Also, its adjustable hop up will help you aim and focus on targets better. If you can’t handle its stock, just fold it in. You’ll get good accuracy and cover plenty of range.

If you want a sniper rifle to cover good range without a hassle, the M40a3 Sportline sniper rifle is just what you need. We used 0.20g BBs to hit targets more than two hundred yards away.

Here’s the truth…

Using a higher weight of BBs, but within our recommendation of under 0.30g, will give you a good range, helping you win games, even as an airsoft sniping newbie.

The package includes an adjustable cheek rest that’s good for support. Being in a comfortable position and finding it easy to shoulder the gun will surely help you shoot more precisely, covering better range.

4. Versatility 

ASG M40a3 Sportline is a replica of the United States Marine Corps designated rifle. This real rifle comes with features and functions to help you take down opponents during airsoft combats.

Honestly…

This gun wasn’t too heavy – even after a few long combat sessions. The weight goes all the way to the back, supported by your shoulder. It’s a solid platform with a smooth bolt pull and topnotch bolt action.

The M40a3 Sportline features an adjustable cheek rest that gives you a good grip and helps you shoot accurately. It also comes with removable stock pads you can decrease or increase. The ergonomic grip will provide you comfort and balance for better precision and accuracy.

You’ll also get a Picatinny rail to attach accessories like the scope, which will give you good vision to make really long shots. 

Mind you, this rail wasn’t particularly sturdy. And you’ll need to get a scope for better precision because this package doesn’t come with one. 

But…

With these existing features, ASG M40a3 Sportline performed splendidly. The magazine holds twenty rounds, and when we used the 0.20g BBs, they traveled circa 500 fps; that’s more than we had expected.

A great gun, but for more action right out the box, you can get the proline version that comes with higher quality control and a better internal fit. 

It is an upgraded version of the m40a3 sportline.

nd retractable stock for better utilization and aiming. The rail allows you to mount other accessories you might need for better shots.

5. Durability

Everything about the construction of this rifle means you’ll be using it to win battles through several seasons.

From pulling the bolt to using the safety switch, handling the bolt action rifle felt authentic. It never fell apart, even under the scorching sun and some tough conditions. It stood the test of time, even as we kept up shooting relentlessly to check its strength.

Turns out…

The ASG M40a3 Sportline barrel is constructed with both durable polymer and metal. The upper receiver, which is also full metal, won’t snap even when you mount several accessories to it. And the brass cylinder is just as strong as that of a real gun.

The lower part of the rail is made of polymer that’s more rigid than rubber, which several other sniper rifles use. But, when we pulled a little hard on the bipod, the rail snapped on one of our test models. So, be careful not to run the gun into a wall.

On the whole, the magazine is sturdy – just be careful not to overtighten the screws.

Here’s the thing…

Not the best you can get at that price, but the M40a3 Sportline utilizes lightweight polymers – like with the polymer stock – to give you a dependable rifle with the strength to survive long years of usage, whether you use it occasionally or intend to snipe with it frequently.

6. Ease of Use

My team enjoyed using the m40a3 sportline sniper rifle, thanks to the fact that its so easy to get a handle on.

Even as an airsoft newbie, you’ll find it super easy to assemble. The manual is an easy read that shows you where everything goes. That’s if you haven’t already figured it out yourself in a  few short minutes.

The package includes a speedloader, which makes loading the magazine quick.

But that’s not all…

This rifle has a real smooth bolt action. It’s a quick way to shoot down targets on your list. Easily pull the bolt back, and see consistent shooting action at a super muzzle velocity of 450 fps. Sniping newbies will find the extremely light bolt action easy to operate, too. 

Also, find the adjustable hop up on the left of the sniper rifle. Since the hop-up is external, it’s easier to locate and adjust. You only have to slide the tab to achieve more range and accuracy.

When I first saw this bolt action United States Marine Corps replica, the sheer size was surprising. I thought it would be difficult to carry. 

But at the end of the day, all you have to do is to retract the stock to make it more manageable.

You’ll soon be hitting targets with this authentic gun that’s easy to use.

Frequently Asked Questions (FAQ’s)

1. What are the dimensions of magazines?

Magazines come in different types. You’ll find the high capacity, mid capacity, and low capacity magazines suitable for specific purposes. 

These magazines vary in dimensions. For instance, that of ASG M40a3 Sportline is 4.09 x 2.52 x 1.5 inches; 0.81 ounces. The magazine holds your rounds of BBs. So you need to get the perfect fit for your rifle.

2. Will this work with a double Eagle M62?

No, the Asg m40a3 magazine will not fit into the Double Eagle M62 rifle. This one’s magazine has the dimension of  6.4 x 3.8 x 2 inches; 5.6 Ounces, which is a lot different from the Asg m40a3 magazine. 

So if you’ve placed shipping orders for your rifle, make sure to check when it arrives. You need a compatible magazine for your rifle to work.

3. How accurate are airsoft snipers?

Airsoft snipers can be as accurate as you want them to be. The best ones often come with long barrels that give you accurate shots. Other features like the adjustable hop-up, high velocities like the Asg m40a3 450 fps, and scope will give you more vision and precision, helping you achieve more accuracy.  

But that’s not all…

You’ll need to use the required BBs, if you want to be as accurate as possible, using these guns for sniping.

4. Are these reloadable?

Sure, you can reload your magazine. That’s the only way to keep the pellets flying where you want them to go. While some rifles have easy-to-load magazines, you might find it challenging reloading others during a hot airsoft battle. 

Luckily….

You’ll get a speedloader with your Asg m40a3 to make reloading quick and easy.
