Have a mk iv myself not too familiar with the buckmark.

But the mk iv is plently customisable changed out the grips and trigger and other few bits and bops.

Got granted the use of a sound mod for it too and it makes a good suppersor host.

The disassemble button is a godsend with how often semi auto 22s have to be cleaned.

It can be a lil fussy with certain ammo brands such as tac 22 but these issues can be fixed with 3rd party springs and parts.

No complaints and works well as a general plinking and target shooting gun.

Getting a mod was some achievement.

What is your other pistol?
