Harris Bipod On AR-15

[wishin]

Got my bipod mounted yesterday and thought I'd share my method for those interested. My rifle is a DPMS 6.8SPC carbine, 16" barrel. Since the lower handguard has holes in it too large for the QD stud and too close together to permit drilling a new one, I had to do the following:

Used a 10-32 threaded QD stud.

Bought a Tee nut without prongs (aka hat nut/capture nut) in 10-32 X 9/32 at Lowes (comes in 2 per pkg for $4.00), filed two sides of the flange 180 degrees apart to the same inside measurement of the handguard recess;

Cut a rectangular 1/8" aluminum plate (old road sign) to span the distance of the first 3 holes in the handguard and to the same inside measurement as the Tee nut flange, then painted it. Gives you force displacement and also acts as a spacer at the underside;

Used a 1/4" nut, threads drilled out with a 1/4" bit to accomodate the Tee nut, as a bushing to insert in the second most forward hole in the handguard. The hex points on the nut may need to be filed a little bit. (you want a snug press fit).

Put everything together and screwed in QD stud (since the 1/4" nut sticks up about a 1/16" no washer is needed. The bipod keeps the stud from coming loose).

DPMS carries a couple of adapters for those handguards. They're available on the DPMS website at http://www.dpmsinc.com/store/products/?prod=329 and http://www.dpmsinc.com/store/products/?prod=1634.

The first one sounds similar to what you've created.

It would be interesting to hear from someone that's had experience with that mount.

Harris Bipod Adapter

I used that adapter on my DPMS carbine. Works great. I think I bought mine at Midway. Used Loctite on the stud and it's a solid mount.

That's good to hear...........but, just think of all the fun I would have missed out on if I hadn't worked on my answer to the real mccoy! besides, I probably saved a wopping $10-15.
