This is probably a question that is too subjective for anyone to answer with authority, but I wonder what the difference in loudness would be between the S510 Xtra FAC RIFLE and the 12ftlb S510 CARBINE. A longer barrel gun is quieter than a shorter one, but longer with more power (FAC)... do you thi...

You might want to check out airarms hunting SA on you tube who reviewed the US extra Fac ,and whilst the 12ft lbs version is a great rifle, the US extra has limitations on usable shot count. You will see what I mean when you see the graphs on the video. Thanks Spike (and of course you too, Roger), ...

with high power, carbine barrel and no moderator you will only kill one critter per day unless you can run as fast as them! BANG! Yes, but according to the AA website, it looks like the high power Ultimate Sporter (Xtra FAC) is *ONLY* available in rifle length and not carbine. I've been trying to g...

Hi, Do you mean this from the Air Arms site:- m Mark Geez, no, I didn't mean that one. How did you find that??? What I'd found (and referenced) was this: http://www.air-arms.co.uk/showroom_product/s510-ultimate-sporter I see now what's going on... I'd clicked on the "Sporter" section and ...

Just looked at Airgunsource and yes that's the carbine 15.5" barrel, the one on A/A website is rifle and will have the 19.5" barrel. The carbine version in FAC is not shown in A/A brochure over here in uk, only in 12ftlb. Had another look at Airsource picture, that's not an FAC carbine, l...

Just had a look in A/A brochure, the S510 U/S Xtra only appears to be a rifle, there is no mention of it in carbine format, the S510 Xtra is in both rifle and carbine, but this is only in a standard stock not ultimate stock. The S510 U/S Xtra has a 19.5" barrel and it's shrouded. Rog Not quite...

I'm about to place my order for an AA S510 Extra FAC S/L Ultimate Sporter in .22 caliber and my dealer says besides the Carbine which I was pretty sure I wanted, he also has it in regular length barrel. I didn't even know the Ultimate Sporter was available in other than the carbine because that's al...

For me, I would set the power to whatever I wanted, then lock it to that power, and use it like that, find it's best pellet, and not bother with keep adjusting it, you might prefer to do it differently, I don't think my head could handle trying to remember all the different settings . Rog Thank you...

Thanks Roger, yes it does help. But what about the adjustable power levels? How do you folks use them in practice? Do you pick a power level, determine the best pellet for it and then find and set the optimum zero point? Or do you vary the power (and thus your zero point, etc.) in use? My understand...

A friend of mine and I both are in the market for a new .22 rifle and we've effectively narrowed the choice down to between the Air Arms S510 Extra FAC S/L Carbine and the S510 Ultimate Sporter Extra FAC S/L Carbine. (Not that I want it, but is the Ultimate Sporter really also available in a non-car...
