The R.A.D. Maxim 38 with Microtubing Alignment System uses the Maxim 38 peep, but
with a modified tubing post, allowing the use of smaller-diameter tubing for increased speed and reduced "slap" noise.
Available: 3/16", 1/4".
I bought this sight based on one of my son's recommendations. I had just put on a new string (cheap one not a custom one) and I have to twist the sight just after I nock the arrow.
I love the view and no longer have to be bothered with the tubing that has come off too many times in the past at just the most inappropriate times.
