.. Hey guys.. Please tell me about this gizmo.. I know they're available from places besides Hart's.. But from what I've seen there I'm still confused.. Does this thing come ready to use or do ya need all the other "optional" pieces to use it.?? I'd like to be able to use one sitting or standing with a Tooley MBR stocked rifle and maybe occasionally a narrower flat-bottomed stock.. What's the scoop..?? Thanks in advance... d:^) JiNC PS- For those wondering why I'm interested in this tripod when I make my own.. Mine is a bench rest that can be converted for field use.. This seems to be mostly a field use platform.. And I'm still trying to find a reasonable machine shop to do the work..
