Well I have been working on a few things lately and might be doing a couple mods sometime soon. I have a P90 I am working on as we speak for a fella, and an M60 box loader I am working with in attempt to make compatible with the Dye DAM mag feed design. A lot has changed since I have been out of PB, but on the bright side that leave more room for new mods previously not possible.
Well I am assuming you mean who came up with the layout?
It was Ranger Rick who added those particular functional aesthetics, such as the suppressor, sight, light and laser. I came up with the paint scheme and built the over all marker setup with the ups I have come to feel are the best of the best per each category, arguably.
So Ranger Rick took my advice and allowed me to use the parts of my choosing and thus this bad boy was born!
