The first question that would needed to be answered is what do all these parts have in common. That answer would be up coming projects at Gun Lab.
The Cetme, H&K, 05 , G-41 G-43 and 03 pictures is for the 05 project we are working on. The fire control group is changing to be a copy of the 03 rifle. The safety will be going back to a G-41/G-43/03 type. The magazine will be more in line with The G-43 /03 type. There is a great deal of design work that needs to go on to make the rifle.
The AR-10 bolt is for the AR-16 rifle that is next on the list of rifles that we will be building.
I like single shot rifles and with a friend on mine (Orin) we are working on making usable drawings of a number of them.
I have a Scottie rifle that someone sporterized the stock. Ian from forgotten weapons let me borrow his parts so I could make the correct ones for my rifle.
The destroyer and AR-70 parts are for my rifles and needed to be repaired and measured.
Last but not least is the EM-2 bolt which is being reversed engineered to try and correct a few problems with the rifle design.
On to the pictures.
Have you any interest in making an EM2 receiver, just for the hell of it ?
I know where the original drawing are.
