I am selling this 1911 Nighthawk Custom I have had sitting around for a while, it was given to me as a gift by a friend and I used it once at Nyvång. An RA-Tech NPAS is fitted to adjust from below 1 joule above 1.5 joules. Also included is a Cybergun Colt 1911 extended magazine from Tactical Store. I don't have the tool for adjusting the NPAS but I think it's a small hex key.
This gun kicks like a motherfucker but last time I used it it had some issues with getting stuck on the hammer (apparently is a common issue for these 1911's) mid cycle. I had the gun stripped and cleaned/serviced by Airtec Malmö but haven't got any Co2 to test it. The magazines have had empty Co2 capsules in for a few months the o-rings might need to be revived in silicon oil or replaced if there is a leak.
