Nice piece of lumber on that one. Believe it is a little lighter color than most I’ve seen recently, grain stands out nicely. Mine loves the AA 8.4 but is surprisingly not a fan of FTT.
I have used those later Williams airgun receiver sights, but only on CO2 guns so no idea how well they stay put on a springer. I do have several Anschutz diopter sights, but they have two fairly large slotted thumb screws on a long slotted piece that fits the dovetail rail on the gun, so a lot of clamping surface .. I have never had a problem with any of them moving. My older Beeman/Williams receiver sight fits the dovetail snugly, none of those little allen screws to clamp, but it does have a larger allen set screw that clamps down on top of the receiver, so no movement from it.
that air force rear sight can also be put on a scope mount with scope stop. I thought about getting one, but they are too pricey and my eyesight is not too good, so I'm afraid that I wouldn't be able to see what I'm shooting at.
Bayman has a Tech peep sight on at least one HW and seems to like it quite a bit. I’ve seen several other folks sing their praises. Not sure which fits the HW, but if the AirForce stays on back order might be worth looking into. I have a Williams FP-TK on a Diana 34, no problems so far with it staying put.
I have never had an issue with a Williams peep moving on a springer, BUT there is a right way and a wrong way to install a Williams. The two very small allen screws on the side of the sight for mounting are only there to take the wiggle out of the sight when getting it mounted. Do not over-tighten or you will easily strip them out. You anchor the sight tight with the large slotted screw on the top of the sight as the final step.
I use rubbing alcohol on my dovetails and sight mating surfaces to clean them and then a little clear nail polish when I install them. I usually put a mark in the sight and reference it to one of letters or symbols on the “billboard” at the rear left of the receiver and grab a picture so I can check it now and then. To date I’ve never had a sight move on a 30, 35, 95, or 77.
I used to flip flop between the Williams peeps and a scope almost daily on my first Hw30. It was a breeze and no scope stop needed with good rings with a recoil pin. I mounted the Williams as far back as I could with still being able to use the safety button. I used a 2-7x32 Airmax mounted on T02C Sportsmatch rings that have a recoil pin. When I wanted to scope the rifle I simply took off the Williams elevator portion and left the base. Mount the scope with the recoil pin in a hole ahead of the Williams base.. The ocular cleared the Williams base easily and the scope never moved because I used good rings with a recoil pin.VERY EASY.I loved shooting that rifle with both sighting systems so much that I was constantly flip flopping between them. Eventually I realized that I simply needed another Hw30. So I bought another one. If you don't have the money for another rifle I gave you your solution above.Enjoy your new rifle. It probably won't be your last. Trust me. HTH
