Sure, all I needed to do was mount a weaver rail. Got one off Aliexpress for a couple bucks and cut off a 4cm section which I mounted onto the stock. I put on a light UTG bipod.
But not sure if a bipod is needed or desirable because the gun is so light to carry and easy to shoulder. Bipod, even the light UTG, is a heavy implement for such a light gun. I am therefore using shooting bags instead for my 2nd PR900-w. Did not mount a rail on that one, and it looks much cleaner for it.
Thanks for the suggestion. Your are right about it being light and easy to shoulder. That is an important feature when I want to grab it for a squirrel on the deck. A Marauder it is not!
