The smaller plenum is a down grade but if you were already in the market for an M4 Compact, the price difference of the Micro is offset by the ST upgrades alone.
While I appreciate a compact rifle. There’s just something about this one with the sable tactical bits on it that remind me of the Klingons from Star Trek. Not to my taste but I can see how this would be handy in the field.
Nearly a 1000 pellets through mine and love it, single hole groups with JSB Diabolo 8.44 4.52‘s out to 35yards, more testing next week on our 55yard range
