Mercury Rise MUB 50 

So I took it apart and found that you can remove the mag lock so you no longer need to have the safety engaged to release the mag. I believe if you turn the velocity screw counter clockwise, the power should increase. Big fan of the MUB 50 bro. Great video man

That would definitely hurt.

Awesome stuff Johnny! Looks liads like my hdr68, Cheers!

I wear this gun in a pocket holster, i bought a cheap on Amazon for like 10 bucks, i wear it in my left pants pocket with handle of gun pointing forward instead of backwars, it keep that eject button from getting pressed on by accident because even in fire mode if you hit that button by accident ita move like a half inch but dont come out but it wont feed if it does that, its gotta be all the way in, so in self defense its kind of a useless gun, a belt holster wont work out at all because of tha mag eject button, i rather carry the revolver one or a hdp 50 modified or byrna le because you dont have to worry about that, but so far the way i wear it, i haven't had it push in much but i do push the bottom of my pocket evey once in awhile to mag sure its push in and i keep gun on fire mode!

Hello, I just discover you channel, I'm french and we know Umarex HDR/TR50, Vesta PDW and LTL Bravo. Do you already have test them to compare the power ? Do you know the number of koules for this Rise MUB 50 ? Thanks

Would you recommend for home defense?
