Deciding that I wouldn’t add a side-saddle to my Mossberg 500 for various reasons and not wanting to drill holes for mounting a plastic stock saddle to my new Knoxx CompStock, I decided that an inexpensive nylon butt cuff would do the trick. The problem of course, is that:
A. The CompStock has an unusual design which bulges to the rear.
B. Because of said design, a standard butt cuff would sit too close to the palm grip for comfortable shooting.
C. I’m a firm believer in overbuilding things so they last.
So of course that left me with the decision to slap one together out of materials I had on hand. I had a cheap nylon bandoleer which I hated but was loathe to throw away as well as snap fasteners from a leather sheath project last year.
Here’s the result (sorry for the crappy pics, I was impatient!):
Now because the standard stock has a horizontal top and a bottom that angles about 45 degrees or so to the rear, I lopped off the corner of one side so it ran parallel with the edge of the CompStock’s raised lip when fastened. For that same reason, I angled the fasteners to make the best use of the opposite edge while snapped. And because it’s nylon, I singed the ends and pressed the material together so the melted portion would seal itself and not fray after it was cut with scissors. I also made sure that the generous lip of material on the top side in that pic was facing forward so the brass wouldn’t scratch the stock. Four shells takes a lot less space on this stock horizontally than vertically and as you can see in the pic below it doesn’t come anywhere close to reaching the palm grip area or where my wrist starts to angle out while holding it.
Did I mention that I’m left-handed? I thought I’d throw that out there in case someone wondered why I made it this way.
The hardest part of course is measuring it so it didn’t slip off. Gathering the material was hard because I wanted the fasteners close to the bottom and on the opposite side where they wouldn’t bruise my cheek or brush up against my sleeve. Once cut and built it was tight enough that it takes a big of effort just to fasten the snaps and since it’s nylon similar to say a seat belt style of material and not elastic it doesn’t stretch. To further make sure it doesn’t move, I made a hole through the very bottom of it through which the sling mount goes through since on the CompStock that part is a couple inches forward compared to the standard stock.
Finally, I doubled up a medium strength fishing line and double stitched the material between each shell to enhance the double stitched thread that was used in the first place. Shells are nice and tight and there’s no worries of them falling out.
Here it is mounted:
Here’s the opposite side:
When I shoulder it, neither the shells nor the fasteners come into contact with my hands, my sleeves or my cheek and in a pinch it sits low enough to use right-handed. The only thing I have left to do is decide whether I want to cover the underside where the snaps are located with hockey tape or sew on a thin leather patch so the metal doesn’t scratch the stock.
I’m not an artisan by any means and could probably do a better job with a bit more time and patience but I wanted to share this with those of you who have a CompStock but don’t necessarily want a side-saddle.
