Just got a 68 automag classic. I would like to upgrade it to create something similar to H4ZE's new mag: http://www.pbnation.com/showthread.php?t=4071689
My question is, considering how much would need to be replaced - frame, body, valve/bolt, etc. is it cheaper/easier to start from the ground up, building a gun from individual parts or starting from the stock gun?
Now that I have a stock gun in hand, it seems like starting from the ground up would work just as well. Only part I'm not sure of is the rail, can you buy those individually from somewhere?
My apologies if this is an issue that has already been discussed ad nauseum. Any thoughts would be appreciated!
