Adjuster for turning down.

[Deano1]

Hi all, I've just acquired my first Air Arms rifle, it's a second hand s410 carbine. The power is spot on averaging 11.4 ft/lb, which is ideal for my rabbiting permissions, but I have a chance of some night ratting indoor, and would like the chance to turn down the power to around 6 to 7 ft/lb, basically to save air and reduce damage to walls.
I have seen an adjuster on "the bay", but i don't know a lot about it. I'm thinking it is to open and close the transfer port. Could someone enlighten me please.
Here is the link. Thanks

Hi Deano i am not 100% but fitting an adjuster to your s410 would make it a potential section 1 FAC,
as not only could you turn it down to your required ftlbs, but also turn it up and above the 12ftlb max.
Even though your intentions are honest to minimize damage to buildings, the powers that be do not see this.

Interesting.

Would all the S4**'s and S200's fitted with adjusters by Air Arms prior to AT now be considered Section 1 ?

I see.
So if I was to fit a hammer spring that made my rifle sub 12 ft/lb with a fully open transfer port, I should be Ok. Or do you think they would class it as FAC just for having an adjuster fitted.

The legislation says that your rifle should not be "Capable" of more than 12FPE.

If you fitted a 6FPE hammer spring it's unlikely that the rifle would be able to output more than 12FPE. Having said that, without a standard test who can say what test procedure could be used.

There are many, many, AA rifles out there with adjusters fitted that are easily accessible, after all that's how they made them.

Testing isn't a problem, I own 3 chronographs.

The only Chrono that matters is the one the test house would use.

what ray is saying is, without a standard police test they can use any test procedure that they want too too produce any test result they want

Here's is a little info not many of you know, and I'm not being a smart arse either.
This is from a top gunsmith I often have dealings with that does a lot of work for forensics.
If a police officer takes your gun, tests it and says it's over the limit, you can, and are within your rights to ask for the calibration report on their chrono.
9 out of 10 will give you your gun back and say something silly like "just be careful".
