Love that gun! How is the scope and what size?
This one in the picture is a .25 standard with the Discovery Optics VT-T 4.5-18X44 SFVF that Brian sells. I'm only able to shoot out to 25 yards right now, but I can put them through the same hole. I'm new to the Edguns, but Brian has been a real help with all of my questions. The biggest plus for me, when when I first picked it up, is it's very solid. I probably could use it as a club if I ran out of rounds while hunting, and it's still be functional and zeroed.
I like the way that top edge of the stock curves downward on each end--major quality control. And that side lever has gotta be cool. Have you tried the QR code on the breech yet? Just guessing it gives out info on any product updates, maybe?
I use a one point Magpul with a clip-on sling mount on the pic rail for my Mutant. Some guys don't like that method, but pull I pull-test it before going into the field and don't have issues.
The R5M already comes with a sling attachment on the frame
