There’s so much more to choosing the best airsoft SMG than just power, aim, and price. 

Whether you are a newbie or a veteran with an airsoft gun, you will eventually know what your preferences, what type of guns and which features are best for you—which can help you more specifically narrow down the various SMGs (submachine guns) out there. 

All airsoft guns are different—whether it’s by shape, size, and strength. However, every player is also different, so you have to know what features are most important for you and that will lead you to be able to choose the best airsoft SMG that fits the bill. For some, you will want extreme stopping power, others will be perfectly content with a gun that can accurately place their target with extensive range.

In this guide, we're going to not only compare the best airsoft MP5 & SMGs out there, we're going to break down the guide for the buying process, taking each feature and factor that you should take into account before making the purchase.

Let’s first take you through the various advantage of choosing an airsoft SMG and then go into what type of player you should be if you choose to use one.

Advantages Of Airsoft SMG (Submachine Guns)

Airsoft SMG Advantages

Especially if you are new to airsoft, you might choose a role without even knowing it, simply by choosing a particular airsoft gun. To choose the airsoft gun perfect for you, consider these features and factors that can directly affect how you will play.


You'll need an airsoft SMG that is compact and easy to carry around. Especially since most games last for a long time and can cover a good amount of distance, you should be able to carry your weapon around with you and stow it away without any issues.

Not having to worry about a longer barrel can also help with maneuverability when your playing in close quarters combat or fighting room-to-room. It is extremely ineffective if your barrel is snagging on your surroundings when trying to clear a building.

Even when you're not playing, being able to store it in your house or garage without it taking up much space is also a great feature to have, especially if you are living in an area without much room. Having a compact gun will also lessen the chances of another play spotting it out on the field—and you all know, the less conspicuous you are, the better.


This might look different for everyone because every player is a different size, weight, and have various limits of strength. Therefore, it’s important that you are sure that you feel comfortable when carrying the gun around and it’s not as much of a weighted burden—especially if your target is a few miles away.

Another reason why you should opt for a lightweight SMG is to be able to conceal it as much as possible. That way, you have the best chance of being able to take someone out without having them spot you first.

Great At Close Range

Depending on your game style or strategy, you might want to opt for the SMG because it is great at close range. If you are more of a sniper, you shouldn't opt for the SMG because it isn't exactly designed with the preference of long-range shots like a long rifle is.

The submachine gun is an automatic weapon that weighs less and is smaller than an assault rifle and a full-sized machine gun.

Especially if your strategy plays to your strengths of shooting point-blank shots, the SMG is perfect for it and can be accommodated or upgraded to your personal player preference.

What Type Of Player Uses The Best Airsoft SMG

The SMG is a perfect fit for an urban rifleman. If you have been playing airsoft, you will notice the various roles or positions of certain players, which is normally based on skill and also personal preference. If you tend to be more like a rifleman, then your best bet is to invest in the best SMG on the market.

Most of the other players will also be riflemen. They are the ones the team turns to, to deliver the majority of the strike force to the other team. Basically, if you think of chess, the riflemen are the pawns and are very versatile—and have the main role of completing objects like attacking, flanking, and ambushing the other team.

The SMG, as we mentioned earlier, is perfect for the urban rifleman, which will usually be within 120 feet of distance to their opponent.

MP5 vs UMP 45 - Which Is The Best Airsoft SMG

MP5 vs UMP 45 Airsoft SMG

As we already mentioned before, the best gun for your situation and your player preference can change from player to player. Therefore, when trying to choose between the best airsoft MP5 and the UMP 45, you can take these features into account, where they both bring certain factors to improve one’s game.

The MP5 is the one most airsoft players turn to, which features the suppressor and collapsible stock, which makes it perfect for the player who plays in a CQB or MOUT environment. Especially with its compact size, players with the MP5 don't have to worry about being able to wedge themselves into small spaces can be tricky with their profile and weapon.

You can also easily upgrade your MP5, which sets it apart from the UMP 45. The magazines are also longer and much narrower than the other types, making it perfect to carry around multiple mags—with a large variety of high and mid-caps, too.

Even though the UMP 45 has a small profile, it still packs a punch with its stopping power.

The bolt actuates from the gas, which is located in the magazine of the UMP 45, which gives it a whole new, realistic experience when shooting the two-round burst—with a LOT more recoil.
