Homemade P-Mag! (pics)

Mar 27, 2012
I wanted a shorter, lighter mag for my Specialized Dynamics .260 Remington for an upcoming wolf hunt, range use or shooting from prone position. Since no one makes a short polymer mag for the DPMS LR .308, I decided to make one.
I started with a standard Magpul P-Mag LR 20 for the DPMS and cut two inches off the bottom with a stardard cut-off wheel. Then I cut two coils off the spring. All I had left to do was drill some 1/8th" holes and rivet the base plate back on. I finished by painting the rivets flat black to match. The whole project took about 30 minutes.

Voila! Now it's a full two inches shorter and still holds 12 rounds. It's the perfect size for long hikes and benchrest work. Magpul should offer these. Hint, hint!

I can understand why you don't want to use the ones that come with the rifle, the 10 rounders I've had were pieces of crap. They would hold rounds but didn't like to feed them. I replaced them with some 10 rounders from Knight's Armament and no failures.
