20mm Patriot clone RDA

Got a 20mm Patriot clone yesterday. Really like how it fits the LP Grand. It is almost exactly the same diameter as the LP catch cup.
Built it with dual coil 30ga and sterile rolled cotton. Loving it!

How did you mod it to bottom feed?

I Dremel'd out a groove in the firing pin per Filthy-beasts previous post (thanks Filthy!). It is just pressed into the 510 connection. The one I got did not have a top and bottom insulator like his. It had a hard plastic insulator that sticks up maybe a mm into the build deck. I cut a v into the part sticking up so it would drain.
It came with one stock airhole at about 1mm. I drilled it out to 1/16" and drilled a second directly across from it.
The shop I got it from had it in 22mm and 20mm. I had only seen the 22 mm before, and am not a fan of the rda's that hang over the catch cup. The 20mm fits perfect and was really easy to build.
