Extras and spare/replacement parts for the Scorpion MK5 FT hook system.
Maestro Design’s Scorpion is a fully modular sytem and most parts can be replaced or parts added if needed. All the available parts are listed here. If you have an old design MK4 Scorpion then start searching spare parts here. Nevertheless, most of the the MK5 parts are compatible with the old system as follows:
Fully compatible with MK4:
Butt Pad Kit (adds two pads to the centre post)
Middle Extension Kit (adds 10-20-30 mm to the centre post)
Offset Plates (0-25mm or 10-50mm) to add an offset tot he whole hook
Does work with MK4, but looks a bit different or certain features are limited:

Extra Link 44mm
Wing, Standard
Wing, Extended HFT 2.25″
FolloWing Articulated Wing
T-Rail Limiters (with a 3-way limiter on both ends) 130mm or 150mm

Long Hook, Stainless 152mm
Long Hook, Nylon 137 mm
Short Hook, Nylon 97 mm
HFT 2.25″ Hook, Nylon 57 mm
Some parts are suitable for both right and left handed hooks. but some parts have R/H and L/H versions, please double check that you have selected the appropriate one.
These parts can be bought separately, so you can buy a basic hook and then get the needed extras later, when you already know from practice what you need exactly.

Fully adjustable Field Target hook, with much more versatility than the usual Gemini clones. Everything can be adjusted even in the shooting position, without disassembling the hook. Modular system that can be upgraded later if needed. Massive construction, without any flex and slip, a lightweight and versatile alternative to the traditional metal hooks.
I added a lot of improvements to my professional FT hook design, creating the MK5 (2023) version that will replace the discontinued MK4 (2016-2022) version. Some parts are backwards compatible with the MK4 so the two systems can be combined if you don’t mind some visual differences but I’d suggest not to mix the two systems.
Features on the new MK5 design (see detailed listing with photos and dimensions at the bottom of the web page):
Engraved marks for all adjustments – now you can record and reproduce your settings any time
New 152mm stainless steel hook, 137mm and 97mm Nylon FT-hooks
HFT-compatible 2.25” (57mm) Nylon hook
Extended upper wing base option, for better integration with the Butt Pad Kit or to add half a link length to the upper wing
Slim hook holder links – don’t protrude that much as the old design
Rounded link elements – gives a smoother fit when the links are twisted
Comfortable handle for the loading port of Feinwerkbau P70 rifles. Replaces the original ugly white handle with a much better one. In R/H and L/H versions, made of laser sintered Nylon with stainless steel screws.
With this, you can close the loading port by rotating the handle easily by the two rounded ends, instead of pushing it down with a quite big force.
The handle is combined with an automated safety mark: when the loading port is open, a piece of flexible cable tie blocks your trigger finger, but goes out of the way when the port is closed.
