Thanks guys, that makes sense as the screw end is tapered.  I'll play around with the chrony to determine where I should set it at.]]> Fri, 21 Feb 2025 18:21:51 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1173&PID=12075#12075 S410 gub screw purpose? : Yea, I think Myson is correct,... www.kiwiairgunners.co.nz/forum_posts.asp?TID=1173&PID=12074#12074 Author: Pauly5

Yea, I think Myson is correct, but probably not a lost knob, but an adjustable grub screw. I suspect it will be a cone shape and adjusting it will alter the transfer port size.]]> Fri, 21 Feb 2025 17:27:38 +0000 www.kiwiairgunners.co.nz/forum_posts.asp?TID=1173&PID=12074#12074 S410 gub screw purpose? : Hi Gavin,On my Side Lever version... www.kiwiairgunners.co.nz/forum_posts.asp?TID=1173&PID=12072#12072 Author: Myson

Hi Gavin,

On my Side Lever version of the AA S410 Classic, that's where the high-low power button sits.

Perhaps your button has been lost (?) and this grub screw controls the high-low power setting?

On mine, turn the screw (button) anti-clockwise until it stops - that's High power (32ft/lbs). Turn it clockwise until it stops - that's Low power (sub-12 ft/lbs).

Hope that helps? Big smile

Can anyone tell me what the purpose is of the 3mm grubscrew below the breach block on my recently acquired Air Arms S410 Classic?

I noticed it was about to fall out but none of the parts diagrams or YouTube tear-down videos show it so I have no idea what it's purpose is.  I assume it locks something but it travels a long way in and I don't want to risk tightening it and doing some damage.
