Bought this off here locally; Guy said it was brand new, it obviously wasn’t. However, it is in good condition and working now. Gun fires off a mechanical vortex HPA system, holds up to 7,200 bbs. Just plug into a air system and pull the trigger. No battery required. 150-175 rounds a second. Much faster then any dsg you’ll ever buy. These retailed for 900 with no rails or extras back when the company was around. I have the top and bottom rails. ****NO ATTACHMENTS INCLUDED**** Comes with: Gun, HPA nozzle, air compressor adaptor to run off an air compressor instead of HPA tank. Throw me an offer. Not really looking to trade because I’m trying to get some gen 3 nods. But if you think it’s worth it I’ll hear you out.
