ARC tuning. Sorted my HW35. Mach 1.5

I would be looking at TBT.

What’s your budget?

[TonyL]

In no order of preference:- TbT, ARC, Welsh Willy, Vortek. All will be good.

Have tbt maxi kits in my springers work very well. Especially when paired with seals 👍

I would imagine all of the brands mentioned above by TonyL are perfectly good. I have a TbT kit in my HW35E; I cut the spring down a fair bit, and it's very nice to shoot; smooth cocking, no twang, and low recoil with a very linear feel. If I was buying again, I'd happily get the same.

is the rifle leather sealed or synthetic ? I'd be changing to synthetic as a first step, if your port allows.

Also, when you order your kit, check what gun it is for. I know some well known kits are designed for the current synthetic sealed rifles, and will not fit the leather pistoned (or adapted from) guns.

This thread covers the improvement when adapting the piston to synthetic seal, which keeps the heavier piston and only has some of the stroke benefits. The factory synthetic piston has more stroke, and is 30g lighter, so even better, but you need a ~3.0mm port

Excellent post, Jon, and very valid points re the piston room difference. I do not have the measurements available for the later piston, but on the earlier leather seal piston of the rifle I've just been working on there is 94mm of spring / guide room. So it won't take as much spring as the later ones and guides have to be correspondingly shorter.
