Air Arms S510 XS vs. Weihrauch HW 100 PCP vs. DS Revere.22

This is all my opinion, for what it is worth - and little background to justify my opinion:

I have been on the inside of AA S400 (my own) and the HW100 and a DS huntsman. Grew up in a machine shop, and do airgun repair.

  • Engineering: 1 HW, 2 DS, 3AA. Particularly impressed with the engineering and thought that went into the HW mechanisms. (There is a lot to say here!) I found the AA lacking. Couple of issues I had to fix. Burr on the transfer port, and the main valve concentricity was out, causing it to have a small leak at lower pressures. (This was 10 years ago - ymmv)
  • Fit and Finish: 1AA, 2 DS, 3HW. The walnut on my AA, with Rosewood end caps, and deep blueing, I think this may tie with a Daystate. I find the HW to be a bit heavy, and clunky in comparison.
  • Accuracy - I'm pretty sure all 3 can be tuned to Sub MOA @ 50
  • Reliability - I can only mention the types of issues I have seen, I could be the only one to ever have a main valve break. Don't know. - HW seen mostly leaks, and a broken main valve. DS mostly leaks, and a side lever action breakdown.

Personally I'm also torn between the DS and HW.

I'd probably choose the HW, as it has been around a while, and has quite an established following, to the extent that there are quite a few after market options available. Titanium reservoirs to make it lighter, and it comes in a few 'flavors', Carbine, Thumb hole. The mag also does not stick up above the breech, and has 14 rounds. Keeps the scoping area 'clean'. I would expect the longer barrel (430mm vs 600mm) may be more efficient, Or if hunting - less maneuverable, then get the Carbine. The insides are built like a tank, and I like to tinker.

If I was looking for a light beauty run'n grab'n hunt - I'd go with the DS.

As you said, all great guns - have fun with the one you choose :)

I own an HW100 laminate carbine, and have owned the other two also. All are excellent rifles. One post places the HW last on fit and finish, citing it as heavy and clunky. Yes, it is heavy, and "clunky" maybe, that's kind of subjective. But, in terms of what I consider fit and finish, I find the HW100 excellent, maybe perfect. Weihrauch is a quiet company in the PCP market, and its generational changes are evolutionary, not dramatic. It's a bit like the Porsche 911 platform, a car originally ridiculed as a joke. But the maker plowed forward, and 50 years later the car has ruled its market segment for several generations of drivers. Slow and steady wins the race. Honestly, the other 2 rifles are historically similar, and the "best" choice will depend on personal preferences. The HW has a few features that suit me well, but I would never be critical of the others. 
 
Thanks all! 

One of the previous responders worked in a machine shop and did airgun repair and commented on the impressive engineering of the HW100. I was unaware of the lifetime warranty. I know that the trigger is also touted as being excellent. Power can be adjusted and magazines appear to be solid.

Appreciate the feedback thus far but wouldn’t mind seeing some other thoughts and user experiences also.
