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!

funny you should post that.. I just bougth a DPMS recon in 308 and found a website on converting the LR20 Pmags down to a 10 rd (for those that need them)

Here are the instructions for it..  they used some sort of wire to hold the base plate on the mag - i like your method better.. What size rivots did you use?

That is very nicely done, sir.

Yep, fully functional. I've shot 60 plus rounds without a single hiccup. Bolt locks back when empty every time. NO ISSUES!

Yep, three boxes of ammo. I've been taking her from 100 yards to 1000 and back in increments of 100 yards with three different ballistics programs to see which program I like best. It's expensive yet effective!
