Re: Spring life

Also, the more consistent gun, with a 4 fps spread in 10 shots, was less accurate than the gun with a 9 fps spread. I've found this with both spring guns and some PCPs. A few fps difference has very little effect on trajectory, much less than finding a pellet which really suits the barrel. If you c...

Re: Spring life

As both of mine are recently acquired and not yet run in, I've not taken them apart. So I can't say what pre-load they have but I would have expected your spring to be ok at that age going by comments I've seen from other owners. Perhaps another AAOC member can advise you based on more relevant expe...

Re: Spring life

You didn't say what pellets you were testing. My TXs only put out similar power with H&N FTT for example but produce around 11.2ft lb with AA DF and 11.4 with Express. Also pellet head size can make a difference. Some JSB 8.44 die numbers give me no more than 11, others 11.3 but the fastest are not ...

Re: Altaros reg optimum pressure

Yes Roger, the old type with the conventional dial and pointer gives a much more precise relative indicator even though the indicated values may still be inaccurate. I think I'm seeing some temperature effect because I was expecting the velocity to level out at the previous peak (780fps) when I lowe...

Altaros reg optimum pressure

I'd be interested to hear other's thoughts on the optimum reg pressure. I've just dropped the Altaros regulator set point on my S510 to 120bar according to the std AA manometer. Now I'm getting very consistent velocity as it comes off reg, so consistent it's not possible to see any change from 125 t...

Re: warranty

The gun is used, it may look "brand new" but what date was it made and first sold?

Re: warranty

I've bought two TX200s from different RFDs since AA introduced their 3-year warranty. Both were made before the 3-year warranty came into effect, but both were sold with the 3-year warranty. One gun was used, previously sold by the RFD to another customer but returned in "as new" condition. I'm not ...

Re: S510 tdr

If you look at the specs on the AA website I think you'll find the answer... I'm fairly sure that's where I found the answer when looking for the same info on the S410.

Re: Regulator

I don't know how Altaros do it because I haven't taken the regulator apart, and I can't imagine how either. I understand the hole and what it allows. But the fact is the Altaros does work in terms of regulating pressure at the firing valve. It is not intended to be part of a tuning process: no other...

Re: Regulator

I didn't fit mine, the gun was bought from Roger5 with reg already fitted. Roger set the firing valve to give max 11.4ft lb (as I tested it) with the venturi fully open . When I got it the reg was set a little high (Altaros say they do creep up and need to be reset) so the velocity was a steady 770-...
