Bubonic Upper

[Great-Kazoo]

Had a ridiculously fast twist piece of 338 barrel laying around, a few other junk parts and a free afternoon.



Grendle case necked up to 338, 7.62 x 39 bolt , carbon fiber tube and some aluminum tubing....spare barrel nut, oh and a junk JP gas block that split from the other direction. So I cut it in half and used the other end.



Cant decide which side to slot the upper on and I'll likely have to do a little gas port tuning. Probably cut the barrel back too.
cases loaded @ magazine length with 250 hornady and 300 SMK , 25 G shown for comparrison.
it'll probably use somewhere in the vicinity of 8.5 grs of Enforcer to get it to 1060 fps so it'll be pretty quiet....and diameter wise, work well with a 9mm can.
.375 version coming up next.
For some reason I want to paint it industrial gloss grey ?

Some yellow pinstripes to accent the warehouse flooring finish.

Awaiting videos of it in action.
