Picked up this fun one. Walz rifle.

Picked this fun up. Gotta figure out what I'm going to do for an elbow for the vertical feed, what I can do to utilize the hole in the 12gr area to do constant air, and if I'm going to take the orange off.

12 gram is in it right now to do a leakdown test.

Any tips or tricks I should know about these markers?

Also, what's the twisty thing on the bolt?

Thats to disconnect the cocking rod for cleaning.
