Hey, guys, I'm throwing this one up there to see if it sticks. I've had this gun drawn up in CAD, and can have it manufactured in brass. Cost would be $15 each plus $6 shipping in the US. Same shipping for more than one barrel, so if you want to do an M24 as well the shipping cost won't change. I've uploaded a drawing of the barrel here:

Just trying to find out if there is enough demand to justify the investment in a production run of these babies. Thanks for any input; and you can contact me via email at [email protected]
