I would love to hear your input on this one, I tried to make it as adjustable as I can. The idea was inspired by an Edgun semi-auto kit that Edward never put into production. I made a few changes to Edward's design, first of all he has a safety mechanism that disengages the magazine indexing lever when the bolt is pulled back to prevent double loading, I don't have that (but did account for it if I ever wanted to have one), instead in my design you can rotate the bolt 90 degrees and the mechanism works as a bolt action repeater, you only pull to cock and let it go and the bolt locks in place.
