pietta Remington 1858 sheriffs model comp system

I designed this from scratch im working on a version that can be made of metal if you want to make this youll need 8 #6-32 S heat set inserts (yes S meaning the small 4.8mm deep ones) that i got from https://a.co/d/03hVKTDA and 2 5/8" #6-32 screws and 6 5/16" #6-32 screws which i got from this assorted pack https://a.co/d/01dSmnG2 other than a soldering iron (which i recomend the pinecil if you need one its a good beginner or hobbyist one) that is all you will need you can figure out how they go together now DO NOT FORGET the shelf bit which is the back most section does not get heat set inserts those are pegs i know its tempting but DONT and the actualy comp doesnt get any either the screws go through to the barrel sleeve or middle section which will recieve all 4 inserts that dont go into the bracing sections which are the two small bits and what the shelf (as previously called) screws into for an extra brace and on those bracing sections there are three holes that go straight through those are optional help for structual rigidity if you want to be sure it wont shake loose or the plast breaks first put 3 30mm M3 screw which i sourced from here https://a.co/d/0hoAHfZT others will do these are just the ones i used cause i had them
