Posting my slightly updated WA-based gbbr again. Prowin mags w/ ranger plates.
Not much accessorizing yet so my rails are bare. Looking for a nicer barrel extension as well. Haven't got a gas block or tube.
I didn't take a picture of the other side, but I've got a G&P ambi mag catch (actually the AEG version, filed and forced-fit ). Just waiting on an Iron Airsoft ambi selector to round out the ambi controls as I'm lefty.
