Well, I was really excited to receive my Sentinel v4 Staff last week. I absolutely love it although I've had to order an adjustable coupler because I'm not happy with the buttons not lining up. Anyways, I got to work the last couple of nights with the first set of mods. I've wrapped the recessed areas in a gray/green leather I've had sitting around for some time. I had to use a stitch wrap as I felt a traditional wrap didn't look very good in the short amount of space I had to work with. This is my first ever go at hand stitching, I'm quite happy with the results.
I used a little E6000 on the leather to help hold it in place so it doesn't spin around the handle on me.
I've got some Aluminum Black on order that I intend to use for some weathering and battle scares. I'm also thinking about getting some O-rings (like 44 of them, sheesh!) and putting them on the grooved portion of the handle. I think I'm going to wait and see how the weathering looks first.
