I'd been hoarding these for the still-forthcoming Store relaunch, but there's been some recent demand so I figured I'd post 'em up.
Just what it says on the tin. A drop-forward style P-stock, takes a standard "duckbill" ASA or any rail or other bottomline style mount. About the same length from the grip as a bottomlined 7-ounce tank.
I have two polished ones left, they're $45 each plus shipping.
