Here is a pic of my Marauder.
I plan to get the "Laser" from Quality Stocks and, guess what? ; PAINT IT BLACK. (Rolling Stones circa 1960's)
I got this butt pack off an a "tactical" center fire rifle I have hanging on the wall. It holds a couple of Marauder mags and a tin of my favorite pellets. I also have some closed cell foam underneath to give me a better cheek weld until I can get my medium height rings.
