Update:
Install of the 100cc air tube went quite smoothly. All you Leshiy owners out there, consider ordering one of these!
Adds very little weight, more than doubles shot count, drops the butt for better sight picture and less neck strain, allows you to tune it hot, and balances the rifle much better. The center of gravity is now right at the handle.
Mine has the Huma reg at 120 bar, 350 mm barrel, .25 cal, extended shroud, Dedal with a Streamlight. (need an Akula bad) I tuned it pretty hot at 40 ft lbs (see string below... polymags...note SD; great consistency) and got a solid 23 shots on the reg at that power. This means if I tuned it down to 20 ft-lbs, I would be probably be getting over 40 shots/fill.
Pic is a group of 20 Polymags at 20 yrds... for some reason this gun loves the polys... stacks em.
I did tinker with some 26.8 gr, 29gr, and 33gr NSA's today, and I couldn't group em anywhere near as good as the polys. I have ran a whole slew of VK and NSA slugs over the past 2 months in this gun, and just can't get them to group well. I may keep trying, but honestly, for what this little rifle was built for, 60 yrds and under, it seems to excel at... if I want to hurl slugs I'll grab my R5M, Uragan, Taipan long, or Impact with slug barrel. and man those polys smack HARD. Can't wait for the Hades in .25...wonder if they will group as well as the polys?
Do yerselves a favor and drop a second tube on your Leshem!!
(sorry bout the apple blown all over target... polymag literally detonated it)
