That is some awesome woodwork!

Better late than never I guess. These all started life as 2240s.

This is my Benjamin/Crosman Trail NP Mark II. Actually bought 2, 1 remains in its original pistol platform. This is the one I developed a carbine stock for. Old AR stock I had in my parts bin, wooden dowel "buffer tube", (made from a piece of a closet rod), mounting bracket fabricated from a chunk of an old air conditioner frame. Looks a bit industrial, but functions well. No, this was not my 1st version. This is approximately the 7th version. It's a little inconvenient as a pistol, but a blast as a carbine! Beer cans tremble in its presence...

I have that same Trail np and want to do something similar HOW DID you mount that to the back of gun

Here is the Benjamin P-rod we put together for my fiance son.... I have a talon P and an Umarex Hammer and neither of those are friendly for a 7 year old. This is great and I had such a blast with it myself.

Question, does anyone know of a barrel band with picatinny mount for a bipod? 

Connecting a stock to the Trail Np Mark II has been a problem since day 1. What I decided to do was to drill holes in the pistol stock, bolt a homemade bracket to the stock, then drilled and bolted the bracket to the shoulder stock. So far, no issues at all. And I've been rather rough with it to ensure its durability. I understand it's kinda ugly, but, so far it is a one off, custom made, carbine stock that functions as designed and I like it. This Mark II is fun right out of the box, but, is a blast when you put a shoulder stock on it! This was posted to try and answer "elwoodblues" 's question...

I understand your question, but, I decided to go with a little different approach. I drilled 1 little hole in the foregrip, installed a sling swivel stud, then mounted a bipod to the stud. Looks and works great! However, to answer your question directly, I do not know of a barrel band rail, yet. 

UPDATE! There are a variety of barrel band rails available for the prod as well as other brands of airguns. Amazon, Ebay, etc. Just Google it, lots of options available. 

This is my Prod. RAI stock adater with New England airguns folding stock adapter. Single point sling mount, sling, depinger installed, Tim Hill moderator, cheap bipod mounted to a single sling swivel stud, heavy duty scope rings with picatinny rails, allows me to mount flashlight, laser, and some camera gear in the future. Maybe even some night optics. Also have the Tim Hill hot rod kit to up my power as desired. Ar style stock and buffer tube. Scope is the one included when I bought the prod from Pyramyd air, it's a Mantis 3x9-40 AO, airgun rated. So far, I love this thing. My first pcp, and yes, I am enjoying my journey down the pcp rabbit hole.

A few here, some are repeats in different configurations. 

Nice collection makes me want to start getting into pistols....
