AA S400F Air Tube?

[Mav617]

Hi guys,

At the range the other night, a lad had an S400F Superlite, exactly the same as mine, but with a longer air tube reservoir and more capacity/shots.

Anyone know the best place to source one as nothing on the AA website?

Kind Regards,

could be what you need

Thanks all, rang Kirkwood and Bagnall and a guy there called Richard sorted me out. all ordered.

What are you doing about the shorter barrel?

What are you doing about the shorter barrel?

Yes, I was wondering about that

Would your gun be the carbine action (300 mm cylinder) and the one you saw at the range be the longer classic version (400 mm cylinder)?

If yours is a carbine, just screwing on a classic length cylinder will give greater air capacity, but it will throw up a couple of other issues that will then need dealing with.

Mine is a Classic rifle, not a carbine. Barrel lengths were the same.

So was the other rifle fitted with a 480 mm tube from an HFT500 or the 520 mm tube of an Xtra-FAC?

This is my S310 that is fitted with a 520 mm cylinder, instead of its standard 400 mm version which bumps the shot count by a respectable amount:

To compensate for the barrel being shorter than the longer cylinder assembly it has a muzzle brake fitted and the large fig-8 collar from the Xtra-FAC as well:

Neither, I think AA changed the cylinder length over time of manufacture. Mine is an old one and his was recent.

@rockdrill that is a beauty by the way

Interesting, as far as I was aware the 'classic' has always used the 400 mm cylinder length, which carried over from the predecessor 300 Series.

One small change I am aware of to effect a small internal volume increase was achieved by hollowing out the centre of threaded part of the inlet valve block that screws into the cylinder.

If you like that one here is a trio of S400's I modified over 20 years ago:

All lovely mate. I was going to sell mine and get a Kral, but it does everything I want well so I'm going to throw a bit of money at it. Bigger (nickel) tube and a fast fill connector from Best Fittings. Might look great, might look terrible but we'll hopefully soon know!

@Mav617 put a picture of your gun on here.

So, according to my tape measure the current cylinder is 300mm and the barrel is 410 from where it emerges from the brecch until the start of the silencer adaptor. So it does appear it has the Carbine cylinder fitted but not marked up as one from the factory?

Did you buy that new or second hand?

Reason I ask is that is ether a factory special order where a classic action has been fitted with a carbine cylinder, or, if second hand a previous owner has altered it by swapping out the cylinders, sort of a reverse of my stretched action modification.

Looking at it the trigger blade it isn't a standard factory item (no safety catch) and looks to be brass instead of the black alloy a factory trigger blade would be, so I would lean to it being a modified second hand rifle.

It isn't a carbine as the barrel is the classic barrel, the carbine has a short barrel to match the cylinder length:

I wonder if the PO who fitted the Rowan trigger put the Carbine cylinder on as they are smaller/lighter. I swapped it but am wishing I'd gone for a standard (blued) cylinder rather than the Nickel silver but at least mine will be recognizable amongst the club guns at the range

Also fitted a Best Fittings quick fill adaptor in place of the AA twisty job:

Credit again to Rich at Bagnall and Kirkwood @Rich_B&K for sorting my order so quickly and supplying just what I needed (including the fill valve)
