Umarex Legends M712 .177 Caliber Automatic BB Gun Air Pistol
Design-wise, this one looks like it’s from WW1. If you don’t mind collecting a toy gun from one of the older pistol models, you won’t regret buying it.
Out of the box, the pistol looks very clean. But it scratches too quickly. Better you use some epoxy on the barrel to prevent scratches. If you want it to give a worn look, use 120 grit sandpaper on the edges.
Its CO2 cylinders last about 85-90 shots. If you use it in full auto mode, the cartridges will be emptied before you know it.
For short distance shooting and target practicing, it shots well accurately. But don’t expect anything overwhelming from it.

Buying Guide for Choosing the Best Full Auto BB Gun
Whether you are getting the most powerful fully automatic BB gun or an average one, it’s important that you know the things that make these BB guns worth it. Before you finalize the order, be sure to keep the following aspects in mind, and then go for one that meets your needs the most.
Although these guns are of 3 types, for beginners, I would recommend sticking with 2 types.
Spring Loaded or Single Pump
When it comes to price, these are the least expensive ones if you are buying solely for your kid, no need to spend on an expensive gun.
The spring mechanism is tightly compressed, which takes care of the propulsion when the trigger is pulled.
These BB guns are fairly powerful and can make a serious impact within a short range.
But, the spring mechanism often gets jammed if it’s made of poor quality material or if you don’t handle the gun with care. Also, in terms of velocity, you won’t get the most by using a spring-loaded toy gun.
As you have already guessed, these BB guns have CO2 cartridges inside the gun for doing the propulsion job.
Compared to spring-loaded ones, these get more speed and velocity, resulting in better shooting accuracy. You can take down targets from a medium-range when the cartridge is full.
But, once the cartridge starts to get low, the velocity decreases. So, to target accurately, you will have to make sure the cartridge doesn’t get too low.
Also, you will have to take the hassle of replacing or refilling the cartridge.
However, if you want to get the best full auto BB pistol or gun, this is the only option to go with. CO2-powered semi-auto guns are also way better than spring-loaded ones when it comes to shooting accuracy.
The most powerful fully automatic BB gun would be the one with the highest velocity. Higher velocity gets the most accuracy. So, if you need to reach the BB above short-range distance without losing the accuracy, make sure your gun can shoot at least 400 FPS.
For short-distance shooting or plinking, anything between 330-400 FPS will be more than enough.
Most BB guns come with front and rear iron sights. Whether you are skilled or not, these iron sights will be more than enough for short-range target shooting.
If you want to shoot further distance with decent accuracy, look for a gun that comes with a scope or red dot sight.
Scopes are usually very accurate and allow you to magnify the target. If you want to opt for a scope, crosshair scopes are the best option for accurate long-range shooting.
Red dot sights don’t come with any magnification feature; rather you will see a red LED dot to aim. If you want to shoot faster with decent accuracy within a short range, this is the ideal option to go with.
How Does a Fully Automatic BB Gun Work?
The best full auto BB gun rifle allows you to squeeze the trigger and hold it down to continue firing. It doesn’t stop shooting until you release the trigger or the magazine runs out of BB.
If you are mostly dealing with small game hunting, go for a full-auto gun.
But, keep in mind that both the magazine and cartridge will be emptied pretty soon. So, make sure you have enough supply of both of these.
Oppositely, a semi-auto BB gun doesn’t require you to use the bolt or cock it whenever you fire. But, unlike a full-auto gun, you will still have to pull the trigger to shoot each round. You can continue shooting until the magazine is empty.
Are There Fully Automatic Pellet Guns?
Yeah, you will find several fully automatic pellet guns available in the market. Pellets reach further than BBs. Also, these have higher FPS ratings and accuracy.
But, you will have to reload the magazine quickly. Most full auto pellet guns come with a 12-round magazine, which empties out within a second.
Can I Use a BB Gun for Self Defense?
BB guns were not designed for self-defense. Due to the heavy impact of BBs on targets, it would be extremely injurious for the attacker. These are the best for backyard target practice, training, small games, and plinking.
Technically, you can still use a full-auto BB gun for self-defense, but this would be unethical.
What Is the Most Accurate BB Gun?
On paper, a BB gun with up to 430 FPS velocity, more than a 25-round capacity magazine, and with 2 CO2 cartridges would be the most accurate.
If you are asking for a recommendation, my opinion goes for the Umarex Legends M1A1 BBs Gun.
Hope the above list was able to get you the best full auto BB gun for your shooting needs and style.
No matter which one you choose, be extremely cautious while handling a BB gun. Use the safety lock pretty much every time to prevent any mishap from occurring. If you are getting one for your kid for training purposes, always allow them to use it under your close supervision.
