here are some of my drawings for the piston sys
nice is that made with alibreHi chopper,
Your piston system looks good. Now, I am designing an Adjustable Gas System and this is the first look at A.G.S:
can you draw and post this idea?Thinking out loud - you could make it easier to build by making the block in one piece, then thread or pin the tube into the block. Would be easier to machine that way.
