Didn't notice that, but not a bad solution, actually.... That way they don't need to sacrifice the real estate needed for a large plenum, or have a REAL adjustable regulator for the two power requirements.... I guess it remains to be seen whether the regulator PRESSURE is externally adjustable (it says it has a "dial"), or whether that dial is an "on-off" switch....
Umarex has really "thrown down the Gauntlet" with their new, regulated, bottled, repeater, though.... I assume a small plenum (where would they put a big one?) may preclude .25 and larger calibers without extensive changes (if possible).... but for 99% of the market it will meet their requirements, IMO.... at a bargain price.... The problem?.... moderated means it won't be coming to Canada....
