I bought parts to make these and have leftovers. They will replace your current Hawk Helium button and allow you to run most attachment methods including Tethrd Versa Strap Mini's. Will only sell in set's of three and four. I have 2 sets of 3 and 1 set of 4. Bolt is grade 8, aluminum spacer and stainless steel washer and nut.
Set of 3 - $15 tyd
Set of 4 - $20 tyd
