hcpookie, It started as a barrel stub with trunion from K-var. I it was $14.95. I cut the barrel off at the RSB, and drilled it through with 5/8 drill bit. Then I reamed it out with an adjustable reammer to 16mm. I used my drill press to "turn" (don't try this at home, kids ) my barrel to a little more than 16mm. It's a nice press fit. I don't have a mill, so again I used my drill press with a machinist vise to "mill" my trunion. The trunion is'nt finished because I have'nt decided on what mags to use. I'd like to make my bolt removeable so I'm thinking about pinning it to the carrier just like a barrel is pinned to the trunion. Here's some more pics
Here is my "mill and lathe in one "
droog, The reason for not using a barrel blank is the cost. The uzi barrel you see in the pics. is only $19.99 at CDNN
