Blending the quiet, carbine action of the Ultimate Sporter line with a lightweight, ambidextrous poplar stock, Air Arms has created the ultimate silent hunting PCP. Introducing the S510 XS Stealth Carbine!
You wanted a regulated S510 and Air Arms delivered, adding a regulator to the XS and boosting the power of the increasingly popular .25 caliber. These upgrades result in a PCP that can achieve powerful 44 ft-lbs in .25, 32 ft-lbs in .22 and 20 ft-lbs in .177. Power isn't the only thing increasing in the XS. The regulator offers increased consistency and shot counts from its 186cc cylinder, delivering 40 (.177), 35 (.22) and 30 (.25) shots per fill with minimal velocity change. These long shot strings are further aided by a built-in power adjuster to balance power and shot count.
Each XS features the prized Lothar Walther barrel, which gives this platform its renowned accuracy. This show-stopping system is further enhanced by an integrated Q-Tec Moderator that make this S510 XS one of the quietest airguns on the market.
Air Arms is one of the most detail-oriented airgun manufacturers and it shows not only in the internal components but the carefully crafted stock. This version of the XS features a rich, brown poplar stock complete with an adjustable buttpad. Each rifle includes one of Air Arms perfected 10-shot indexing magazines, smooth sidelever cocking mechanism and built-in manometer.
The Air Arms S510 XS has won fans worldwide and turned heads at the range with shots so accurate they require a double-take. If you want long consistent shot strings that land on target every time, make the S510 XS yours.

How much quieter it is than I expected, how much more accurate it is than I expected
Things I would have changed:would like a lighter synthetic stock like my FX cyclone has
What others should know:I also bought the AAS510fac unmodified, if I had it to do all over I would pick the stealth gun all day

I've owned an AirArms S510 for many years and I must say the rifle is an amazing piece of engineering. Does Pyramid Air sell the Q-Tec Moderator as a part, separately? I'm very interested in getting one. AirArms in England makes it available as a part, but I doubt they would ship such a thing to the US.
No. Pyramyd AIR doesn't bring in the moderator separately. If you are looking for sound suppression, you may want to check out DonnyFL or TKO.
How well does this carbine handle slugs vs. pellets? are slugs recommended?

It has a nice trigger and is very accurate. It is also very quiet, the sound of the hunter extreme hitting the target is louder than the report at the shot.
Things I would have changed:So far I would not change anything.
What others should know:I bought this for squirrel hunting and I am very glad I did. The air cylinder is small and when filled to 250 bar I get about 16 full power shots before it is down to 150 bar, which is good enough for hunting. The weight and length of this gun make it a pleasure to carry in the woods. I use the H&N hunter extreme pellets and the sound of the impact is much louder that the report at the shot. I have used the H&N hornets also and they do not have the "crack" like the extremes.
