I put one of Jeff's folding peeps on the top barrel bolt of my Kibler SMR and it works very well. You will need to order a longer flat barrel bolt(which Jeff also has available), as the current one is too short. In addition, I also replaced the front sight with a taller one. I found when using the small front sight supplied with the kit, I was hitting high with no additional adjustment available on the peep. The combination made a world difference in me being able to see the front sight better. I was so happy with the first peep, I just ordered a second for my Woodsrunner and installed it today.
The brass peep doesn't compliment the SMR but the functionality far exceeds the ascetics in my case.
