Snakeeyes75 Posted June 3, 2016 Share Posted June 3, 2016 Evening! Right I have a Tanaka M40A1 and a Mancraft Co2 reg. (AA 28rd mag Tapped) I'm having real inconsistencies with FPS. I normally use HPA so I'm used to ultra consistent shots however with this is just not useable! The best I can do is set it for 300 fps with a .45 (33fps under the JC limit) as the CO2 seems to spike to the max fps, sometimes a bit over! Anyone have any experience with this kind of thing?

Guest PT247 Posted June 4, 2016 Share Posted June 4, 2016 Are you keeping the CO2 bottle fully upright? Link to comment Share on other sites More sharing options...
Snakeeyes75 Posted June 4, 2016 Author Share Posted June 4, 2016 Are you keeping the CO2 bottle fully upright? I can't. The reg and CO2 adapter sit sideways Link to comment Share on other sites More sharing options...
Guest PT247 Posted June 4, 2016 Share Posted June 4, 2016 You could be putting CO2 in liquid form into the reg which could ruin performance Link to comment Share on other sites More sharing options...
Snakeeyes75 Posted June 4, 2016 Author Share Posted June 4, 2016 You could be putting CO2 in liquid form into the reg which could ruin performance Right... I'm not sure how to sort that then. It's a Mancraft Reg using threadless Co2 Bulbs. Edit, I've also now tried my HPA kit and it's still really inconsistent. The Tanaka short mag seems to be ok (ish). Very hard to set an fps Link to comment Share on other sites More sharing options...
Guest PT247 Posted June 4, 2016 Share Posted June 4, 2016 How are the mags tapped? You using 1/8th npt? Link to comment Share on other sites More sharing options...
Snakeeyes75 Posted June 4, 2016 Author Share Posted June 4, 2016 How are the mags tapped? You using 1/8th npt? A friend did it but he used a 1/8th BSP fitting to get the 4mm line fitting Link to comment Share on other sites More sharing options...
Guest PT247 Posted June 4, 2016 Share Posted June 4, 2016 Maybe it is restricting the air flow Link to comment Share on other sites More sharing options...
Snakeeyes75 Posted June 4, 2016 Author Share Posted June 4, 2016 Maybe it is restricting the air flow Any way of telling? It's a proper milled tap with a neat elbow connector Link to comment Share on other sites More sharing options...
Guest PT247 Posted June 5, 2016 Share Posted June 5, 2016 Could try a wider bore hose or a longer hose Link to comment Share on other sites More sharing options...
