SKS Bipod

My daughter bought me this bipod for Christmas for my SKS. It's perfect and sells for only $22 including shipping! Picked it up on Amazon.com. Here's the link. The store's name is 'The Global Sportsman'. After installing the bipod, I noticed that there's a bit of forward and backward play due to the fact that there's a 1/32" or so gap between the top of the biopod lug and the inside top of the bayonet clamp. I went through my bins of junk and found an aluminum picture hanger; the kind with a jagged side that you nail into the back of a frame to hang it from a nail. I snapped off and filed down a tiny piece less than 1/4" square and slid it into the gap with a bit of LockTite. Now it's as solid as a rock. This isn't the kind of bipod you would want in combat if you plan to hit the dirt bipod first while firing your weapon. But if you shoot your rifle from a bench, I think this will do the trick. Now the question is how long it will last. I'll let you know if and when it fails.
