Pewpewpetie Posted July 17, 2021 Share Posted July 17, 2021 Hi all, I'm new to gas guns and needed some help in lowering my pistol (well dmr'd aap-01) fps.

Dalno Posted July 17, 2021 Share Posted July 17, 2021 Yes shorten the barrel, install an NPAS or just use a lower power gas like R144a Link to comment Share on other sites More sharing options...

Alimcd Posted July 17, 2021 Share Posted July 17, 2021 How long is a piece of string? The unfortunate truth is that the pressure of the gas varies with temperature and so your power output will fluctuate accordingly. You may find that the lower pressure gas creates a new issue and causes the gun to intermittently fail to cycle or vent. Best solution here, shorter barrel. It’s un-DMRing time Link to comment Share on other sites More sharing options...
