MTC Copperhead is what I have on one of mine and Elements Helix (the cheapest one) are both well suited and well priced, the Copperhead is smaller and lighter. Both are 2nd focal plane.
I have purchased 7 air rifles and 2 pistols from Utah Airguns and found both purchase and after purchase service to be great. My last purchase was an Fx Impact Compact with an Elements scope and Josh had it tuned and sighted in perfectly.
I own most of the Fx rifles including 2 Impacts, a couple of Daystates, one AirArms, and a bunch of Crosmans. My go-to gun is the Royale 400. It is always on, first shot, never gets cleaned or adjusted. I will never sell it!
