Extra Sizers are cheap
Won’t fit on DM4s or DM5s.
This thing is remarkable when I first held it I thought it was made out of paper because it was so light. I was shooting in my back yard with some really bad paint in the cold. My stock freestyle barrel chopped 20-30 balls in the hopper. I then used the Stiffi and only chopped 2-3 (you may think this is bad but this paint was very, very poor, it was really swollen and had lots of dimples).
Even on my cocker I don't have a problem taking it on and off.
I only have the .689 size now and if I want more they are only $25
I would recommend getting this unless you have a DM4 or DM5 because it the bore sizer won’t fit, you could just get a regular stiffi though. Other than that this barrel works flawlessly.
