My remix of https://www.thingiverse.com/thing:4713483.
Hardware you will need. Listing McMaster-Carr parts #s
will need one of these for the breech -
Oil-Resistant Buna-N O-Ring
1/16 Fractional Width, Dash Number 012
9452K21
and 6 of these but I'm sure there's a ton of other screws that will work -
Steel Phillips Flat Head Screw
82 Degree Countersink Angle, 4-40 Thread Size, 3/8" Long
90273A108
And finally, you will need a length of 17/32" brass barrel. to stick in Mega_Inline_Brass_4rd.stl. The brass should seat 1cm in the part and glue if needed.
I used 2.5" of brass but haven't tested what is most efficient. Getting 75 - 100 fps.
Build includes this Picatinny hand stop: https://www.thingiverse.com/thing:4154584
