I got a $20 gift card for Amazon from my job for some silly thing, and found
this little doo-hickey.
Was favorably impressed with its solidity. Especially for the price.
It even came with a mini-Picatinny rail that screwed onto my Marlin 795's
front sling swivel, so I can quickly swap between it and my 15-22.
For $20, it works well.
At least with my 10 round mags, the 25's don't play nice with it...
