I'm about to start rebuilding my rig in a month or so, but this is what it currently looks like.
Here it is as it would be if I were on the field.
In the gun, I have:
Madbull tightbore (650mm; stock length is 629mm, so I had to add a silencer adapter)
KA silencer adapter (Dremeled the lip off to accommodate the silencer
KA MBSS silencer (foam-filled, of course)
G&G striker spring
KA VSR bucking (about to be replaced with a Nineball; most of the problems I've had with this gun started when I first put this in)
Tanaka 29-rd magazine
In the current rig, I have:
9oz CO2 tank
some coiled hose that I bought from Palmer's Pursuit Shop
1/8NPT fittings all around, but I made sure to have a quick-disconnect at the magazine
Cheap eBay regulator (says it can take CO2 or HPA, but I only use CO2)
New rig will have the hose replaced with Macroline, and the fittings will be changed accordingly. I'll also be ditching the 9oz tank and switching to a CO2 powerlet adapter, and carry both the rig and extra powerlets with me in a pouch on the stock. I'm also replacing the stock with a real-steel Ram-Line synthetic stock for the R700 BDL short-action whenever I get the cash.
