This adapter comes free when you by the Blackbird.
This is the adapter you WANT for your Drozd Blackbird! Made of hard steel...the best and strongest adapter out there. These Blackbird direct air adapters are made by aerospace machinists with a beautiful satin finish and maximum durability.
This adapter allows you to attach a 20 oz HPA tank to the air port of the Blackbird and also makes a perfect fit as a shoulder stock. The adapter screws into the blackbird air port it accepts all paintball air sources and tanks: high pressure air (HPA); CO2; etc. It is very easy to screw on and off by hand or snug it with a wrench.
Never breaks (not common mild steel) and threads of this adapter will never die. There are cheaper ones, but this is the best! If you want it black, spray it with auto touch-up paint...but why?
If you buy an auto-fire Blackbird, you will want this. Think of the money you will save with HPA as a propellant. And there will be no freezing, a common problem with C02.
