valmet petra / m76 / hunter adapters

adapters for valmet petra/hunter to mount magpul ak grip and doublestar ace ak stock. made to work with the milled reciver. the grip and buttstock adapter is designed to be made out of metal. the angle of the adapter interface with the slant cut is to aggressive and as such expect a small gap there. i will se if i can fix this. as of now the easy fix is to live with it or fill it in with something like epoxy. an other challange is that the ace stock wil end up too high to work with the stock sights. a sidemounted lpvo wil likely line up just right with the cheekwield.this is my ¨final¨ prototypes. they will as far as i know work with no/minor modification that can be done with hand tools. the grip adapter is made to use bolts, plungers and nuts. you have to make the threads on the grip adapter yourself. the stock adapter need to be fitted with a plunger and a bolt with the right threads and lenght for your rifle i belive its m8x1 but dont quote me on that. if anyone try these, please leave feedback and pictures so i can improve the design.i have now also made and added a complete buttstock, it will need minor fitting, adding of recoil pad and a m8x120mm bolt i belive. i also think this designe is solid enough to work when 3d printed in the stronger types of filament. if you try, leave me feedback. disclamer: this butstock and adapters is my own design, and a work in progress. i designed the buttstock to be made out of wood, but the strongest fillaments will likely work for 3d printing it. one could also lay fiberglass over it?if anyone wants to make thier own spinn of this then contact me and i can send original files.
