Great design! I like how the hop plate/nub fills the entire window. - Quick question, what size are the grub screws/required Allen key? - Cheers

Hi Will, thanks for the comments and glad to hear you love the design 😊 The grubs are M1.6, and the Allen key is 0.7. As this is an unusual size we include an Allen key in with the kit 😊

Will this fit the Umarex version?
