Product Specification


How to operate a MUB50 pistol?

Before using MUB50 pistol please kindly allow us to remind that there are two mechanisms you should know. 

Firstly, please DON’T force the magazine all the way into the compartment without setting the safety ON. If you forgot to push the safety ON before ejecting or inserting the magazine into the pistol and you forced the magazine all the way into the compartment, that will break the lever and cause a PERMANENT DAMAGE to the pistol.

 Secondly, please make sure you DON’T push the magazine
release button before using up all ammos. If you have accidentally pushed the magazine release button before using up all ammos, please follow the steps in this video ( to get the leftover ammos from the pistol.

Please watch our tutorial video on YouTube.

VERY Professional / Outstanding Service

I'm always skeptical about purchasing items online as you never know for sure what you'll get and what condition it arrives in. Well, with Mercury Rise I knew exactly what i was getting. Before they even shipped my 2 pistols they opened the box, verified serial numbers, tested the guns, and sent me the video as proof. I've never experienced that before but more "sellers" should do something like that. I was very impressed!! After the products arrived, I had a very minor issue but the great people at Mercury Rise stepped up and handled the issue with great character and efficiency. I'm now a customer for life.
Great Products !!
