Kasey and company have been VERY busy with mil/le orders of all things B&T, production for those contracts as well as their civilian customers, testing new and upcoming products, and all other areas of the business. He's not been around the Hide much in the last couple months due to those commitments. The V10-HD bipod will get here when it gets here, but at least you know that when it arrives...it'll be right the first time out of the gate!
As for "WHEN" that might be...all I've heard from the horse's mouth is sometime this year (Kasey generally, in my experience, won't give much more specific timelines as stuff happens and its better to not have disappointed customers thinking one thing then getting told another down the line). As with all things from Kasey/B&T/Accu-Shot, you'll likely hear about it here on the Hide before you'll see it anywhere else, so I'd stay tuned.
