VERKSTAD FUNDAMENTALS EXPLAINED

When purchasing/utilizing your CCU, for CT, you can’t have a flash hider and need to have the mounted stock. Hope that can help.Compensated and SF variations only impact the barrel/slide and grip size respectively, they are going to do the job just fine Together with the CCU. Should you have a G31 or G32 you could only order the CCU in 9mm or 40S
