Some specs beforehand:
21" gog tac barrel
dual o-ring redz bolt
1951 Russian sks stock.
Bt springfeed 10 round.
Lee enfield trigger/triggerguard
Mechanical operation - no batteries, semi auto
Here is a closeup of the internals. I used a cocker 3 way and blocked one of the ports. Sorry for the orientation of the photos. I tried to flip them in photobucket, but still show up as this here.
Update: got to try her today in the field. Enjoy!
