Feagle sent me their new M40 3x red dot magnifier to test out. I was a but hesitant because I’m not a big fan of red dot magnifiers. I don’t think they have enough magnification for the weight they add to a firearm and their eye-relief is less than I’d like for anything larger than a 5.56mm or other light-recoil rifle. That said, I was impressed with the build quality and features of this magnifier.
It came in totally plain brown cardboard box. Inside is an owners manual, Picatinny side-flip mount, 1/3 co-witness riser plate, and a bag of screws and an allen wrench. The tube/body design looks like an oversized red dot. Even including turret caps with adjustment tools in the cap, which function like flathead screwheads. This allows adjustment to recenter visual position of the red dot in the magnifier’s field of view.
The 3x magnified image seen through the M40 was good with no noticeable color shift, though the image was not sharp from center to edge. The extreme outer edge of the image was soft with slight distortion. While I would not consider this durable enough for LEO duty or combat use, for action shooting, this should be perfectly usable.
