Over size elevation turrets and focus rings for FT shooters

[Regal_US]

Who makes large diameter elevation turret caps for FT shooters in US? Same question for parallax (focus) rings. I've found Rowan engineering in UK who make an extensive range of gizmos for FT shooters: http://www.rowanengineering.com
It would be nice to buy similar items made in US.

Hector Medina makes side wheels. I've purchased two of his Nautilus sidewheels, and never had any problems with the transactions. He's a real gentleman to deal with.

Thanks for responses - this forum is fantastic for people sharing experience. Hunkaluv: it looks like Hector's sidewheels are made on a 3D printer. Are these lighter than wheels made from aluminum (e.g. by scope-werks)? Both look like great resources.

I would guess they are lighter, but if you email Hector, i'd bet he'd know for certain.
