Bestfittings do the slim Jim pump and adapter's for He and pre He gas Rams.
There are instruction's in how to use the pump and adapters,I am not sure but I think the Later gas ram guns do require a higher fill pressure .
Les..
Anyone got any idea the best place to get one from?
Has anyone got one on here they no longer need?
Please pm me
Also any idea of what pressure i need to put in as a starting point
Ie 25 bar
Thanks

£80-odd pump and HE adapter from Best Fittings.
10 or 12 strokes to pressurise the line, then do same again and check pellet speed over a chrono.
Work up in 3-4 stroke cycles, check speed before adding any more pressure.
Often find 11 fpe - ish inside 24 strokes total .
The HE's I've used were brill with a bit of a margin to the 12fpe limit.
Too much pressure and piston seals don't last long. Also the rifle is less than pleasant
to cock/shoot when over-pressured.
Don't recall ever checking actual pressure on a gauge, but as an airline could launch the low volume ram
with just a quick blast of air, I just stay safe and stick to the Slim Jim pump :-)
Have fun, great rifles.

From memory and probably wrong, the early ones were 180 psi and the layer ones 350psi.
Repariere nicht, was nicht kaputtist.
The fill pressure on mine ( can't tell you how old it is) isn't very high. The best fittings adapter kit and a decent bike pump should be good enough
