Another great magpul product - Magpul Industries STR Commercial Spec Carbine Stock

I bought this for my Bushmaster and installation was a snap. The storage chambers make for convenient storage of batteries for my Streamlight. I took an acrylic tube which came with a set of honing sticks for my knives and cut it to fit inside of the rubber plug to store very small parts. NOTE: The rubber plug has a removable "cap" on the inside that I removed so the acrylic tube can be inserted and easily removed with the plug. Be sure you don't cut the tube too long or else the rubber plug won't seat properly.
