My first impression of the Gauntlet is the shape of the breech and receiver. It uses Marauder magazines, and sure looks like a Marauder receiver modified a little to keep the bolt enclosed instead of a exposed bolt on the Marauder. (My terms are probably incorrect, but you get the idea)
According to Airgun Depot's video,
https://www.youtube.com/watch?v=eC-r4JzCTjI, it also has a Qb / Crosman style trigger.
I'm wondering if Umerex and Crosman didn't work out a deal to license the Marauder / Crosman designs to Umerex for this gun. Using Marauder magazines, Crosman style trigger, general look of the receiver, etc. make me wonder.
Unfortunately, we'll probably have to wait till one of our intrepid members buys one, tears it apart, and compares it to a Marauder.
I still plan on buying an Impact in a year or so, (Of course, subject to change), but seeing competition in the low end models is GOOD! I don't shoot competition, so ragged holes at 50 yards are good enough for me.
