Cleaning Kit

A cleaning kit is an essential requirement for any gun. This gun’s cleaning kit contains two brushes, a soft bat, two long rods, and little wrenches.

This BP-12 semi-auto 12GA bullpup shotgun is made of an impact-resistant polymer, making the gun tough and impact resistant. You will find this to be a fantastic feature because you are guaranteed the safety of your weapon. For instance, if your gun falls, there is a high chance that the gun won’t break even from great heights.

Two-Charging Handles

The Panzer Arm b-12 features two charging handles, one placed on the upper part of the firearm, the oversized charging handle. The other one is placed on the right side of the gun. Once you have a loaded magazine inserted, you can crank it back, and it’s going to go forward.

Therefore, you don’t have to strain much while using this firearm because of the excellent grip it provides.

Adjustable Cheek Riser

To get the correct comb height or whatever works for your case, you can twist it, raise it, or lower it to your satisfaction. This is imperative because of the excellent eye relief needed on sight for you to get that perfect sight picture.

My Field Test Experience With the Panzer Arms BP-12 Semi-Auto 12ga BullPup Shotgun

I picked my panzer arms BP-12 semi-auto 12GA-BP12BSSB and decided to go for a field test. For one, I wanted to see and feel the impact caused by the gun upon firing. Secondly, I also wanted to measure the speed at which this great shotgun shoots.

I made a conclusion that;

If you are walking forward and firing, it slows you down. This is as a result of some real knockdown power the gun has. Although it slows you down, the thick recoil pad at the back helps mitigate that recoil and improve the firearm’s general ergonomics.

The leading maintenance practice for any gun is cleaning it. The cleaning process involves removing the small parts and screws to reach all the parts of the weapon. This whole process might bore you in that you can lose screws, and the entire process of disassembling the gun can sometimes be tiring. 

You need not worry; the panzer arms BP-12 semi-auto 12GA shotgun is easy to disassemble, clean, and assemble. 

Lightweight Design

A heavy firearm can be boring sometimes, especially if you will be carrying it for a long-distance or into the woods.

The B-12 manufacturers put this into consideration. Its weight is kept down a little bit with its design and the use of impact-resistant polymer in its construction. 

This is because its weight and everything are right towards the middle rear of the firearm. In the front, there’s not a whole lot of weight.

Not all guns can be used for home defense support due to the different features they possess. The Panzer Arms BP offers you the gun owner confidence and the much-needed stress relief in matters concerning security.

Due to its Ambi features ranging from double cocking handles to the safety levers, any homeowner, whether left-handed or right-handed, can easily use the firearm without much trouble involved.

Long Barrel

This gun features a 20-inch barrel, so convenient for accuracy!

So how does a long barrel help to increase the accuracy of a firearm?

If you are looking to buy yourself one of the best firearms, the essential things that you should have in mind include the barrel length, rifling, and bullet weight.

The good thing with a longer barrel is that it increases the action in the chamber and in turn, increases the speed at which the bullet exits from the barrel.

The Cons


Most people trained on a weapon with a conventional layout will find magazine changes on this firearm awkward. Additionally, having your face right next to the chamber is not very safe. In case the chamber explodes, you can be hurt severely depending on the nature of the explosion.
