I saw a few of these afew months ago, I have used the search function but i'm unable to find it, anyone know what im talking about. Its a top for your tripod that you can rest your rifle on.
The proprietor, Danel Jenkins, is a regular here on the forums (goes by platypus) and is a stand-up guy. You can't go wrong or do any better than PRS for complete tripod units or just his cradles!
Danel shipped me a Medium SSP2 tripod for Christmas, it's worth its weight in gold.
Rest your spotter up there, LRF, rifle etc.. The adjustment range is huge for the size it packs down to.
When you're ordering, match the cradle to your rifles forearm width, the SSP2 is wider for A5 type stocks.
