Built on the tried and true S510 action, the XS TDR (Take-Down Rifle) packs all of the features that small game hunters want into a highly maneuverable and transportable package. Able to break down in seconds, the S510 TDR is built to go anywhere you can.  The addition of an internal regulator, means more shots per fill and unparalleled consistency from shot to shot.

The ultra-lightweight stock features a finely grained walnut fore-end with a removable rear stock that fits together to form a compact carbine. For convenient transport, each S510 XS TDR comes with a hard case with custom cut foam that will fit the action with added space to allow a scope, buttstock, and even spaces for magazines and a tin of your favorite pellets.

Each of these rifles is available in .177 and .22 caliber, with two of Air Arms standard ten-shot magazines in each package. Fill up the gun to 250 BAR  to achieve speeds as high as 1,035fps. Each S510 XS TDR includes an 5 step adjustable power wheel for finding the ideal balance between long shot strings and power. It's super accurate and super quiet due to a fully-shrouded Lothar Walther barrel with an integrated Q-tec suppressor. Follow up shots are quick and easy with the smooth side lever action. While shooting your first mag, keep your extra ready on hand with a built-in storage compartment on the underside of the cheekpiece. An 11mm dovetail rail is included for mounting optics, and a 2-stage adjustable trigger makes superbly accurate shots within reach.

If you want the world-class quality with premium accuracy only Air Arms can provide, the S510 XS TDR answers the call with a PCP that's built to travel.

Verified Purchase

Things I liked: Excellent ergonomics..beautiful walnut.. Superb accuracy...10 [email protected] 1/3 the size of a dime with 18.1gr JSBs! Workmanship is top and finish gorgeous! This is a wonderful, light weight hunting airgun that conveniently takes down to a small package that's easily transported to where you're going. A+++

Things I would have changed: The moderator seems to be permanently attached to the shroud... The manual states there is a thread protector included and that the moderator removes by hand for cleaning and maintenance. There was no thread protector in my package and the moderator appears to be permanently attached! Removal of the moderator is a needed of the barrel is greatly simplified with it removed. I use the Napier pull through equipment recommended by the manufacturer. With the moderator in place it's much more tedious. If PA lock tights these moderators that should be noted..the thread protector should also be included!

What others should know: This rifle and all Air Arms airguns use a fill probe for charging. This probe needs a male foster fitting to connect to a bottle, pump or compressor for filling. In my opinion a $1300 air rifle should include a male foster on the probe. Everything needed to operate this rifle(with the exception of ammo and a fill source)should in the factory shipping container. Purchasers should not be required to buy additional parts and accessories in order to enjoy the level of airgun! With the lockdown on.. shipping times are unusually long... Fortunately mine was charged to 200bar when it arrived which allowed me to function test, mount optics, and zero. But now I'm stuck waiting for an adapter for the fill probe(who knows how long) that should have been in the package when it arrived! With a purchase of this level that shouldn't be the case!

Things I liked: This is an excellent rifle. I bought the regulated model in 22 because I wanted to shorten the stock so my daughter could shoot it. It's also light and points well. As others have noted, the stock is excellent and looks great in walnut. Finally, I like the simplicity of the design. I also own an FX impact that has tons of adjustments. This one has no adjustments other than the power wheel. If you like to tinker, this may not be a good rifle for you.

Things I would have changed: The manual is ok, but not great. I was not sure I got the regulated model until I tested it with a Chronograph and observed the results. Seem as though the manual covers both models. Additionally, there is no mark on the rifle that indicates that it is regulated. That would be a nice touch to avoid confusion. The finish on the walnut is very thin. I may build it up to give it more depth. If you were to use this on a hunt and it got wet, the wood would absorb the moisture from the rain. Also, the manual indicated that the moderator can be removed, I gripped it tightly with a piece of rubber and could not get it to loosen. These are all minor nits. This is a great rifle.

What others should know: I bought the 16 Grain Air Arms pellets based on the review that Pyramid Air did on youtube. I have an FX Chronograph and with the rifle gassed to 225 bar I got 22 shots that averaged 931 FPS. The Low velocity was 921 FPS and the High Velocity was 939. The Standard Deviation was 4.73 FPS over the 21 shots. After that the regulator started to drop off ending up at 714 FPS on the 39th shot. This rifle will easily deliver 25 full power shots with a full 250 bar charge with very little variation. The regulator inside this rifle is excellent. The shots were done on full power, the last click of the 5 click power wheel.

Things I liked: Quiet, accurate, and not so heavy. Feels good in hand. Carrying case

Things I would have changed: Clip seems cumbersome. I got spoiled with the Walther Rekord clip. This is not a deal breaker.

What others should know: If you are looking for a higher end PCP this one will make you smile.

    Any place for a rifle sling?

    • Mark from USA:

      There is a short rail under te fore stock a swivel stud can be mounted on. You should be able to drill and tap the butt to mount a swivel stud. Thank You,Mark

    Any idea what grain pellet they use for the published fps/fpe?
