I needed a cheap way to mount my rifle to a tripod. After dropping $3k on my first rifle and still needing a case, kestrel, data book and some other things a $150 mount was no where near the top of my priority list. A $30 one however....
So I knew I needed something that already mounts to a picatinny rail that i could drill and tap for a tripod screw. What I found was a GG&G Harris Bipod picatinny adapter. Now before you see this DIY and decide to go through with it and order one of these mounts, I must warn you, there are two versions of the mount, one of which will NOT work. It just so happens that my shop had two of these adapters in stock, one of each (had no idea about the one that won't work till I decided to do this write up). The one that you'll need has a completely solid base, the (what I assume to be) newer version has two giant holes cut out of it.
Start with the adapter and remove the sling stud. I simply put an allen key through it to get the leverage needed to take it off. This is the adapter you'll need,

NOT THIS ONE

Then drill a hole using a .201 drill bit and tap that hole using a 1/4 x 20 tap. I drilled the new hole halfway in between the current hole and the edge of the adapter.

That's it! Then you end up with this:

No where near the quality of something like a HOG/PIG saddle or any alamo four star stuff, but hey, it'll do the job for now.
