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:
Wing Base, Standard
Wing Base, Extended (adds 25mm to the upper wing, recommended for Butt Pad Kit)
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

NOT compatible with MK4:
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
High quality scope rail for Feinwerkbau or Anschütz PCP rifles. Designed especially to work together with my FWB Anti-POI-Shift Kit, using these products together eliminates the POI-shifts on Feinwerkbau Alutec stocks. I’ve been using the same solution on my rifle, and the last time I zeroed my rifle was in 2012, need to tell anything more?!?
Made of aircraft grade aluminium alloy, black anodised with stainless steel bolts or silver anodised with black bolts. Elevation 35 mm, reproduces the same dovetail on the top as the rifle’s original dovetail. The in-built slope is 0.71% = 24.4 MOA so any simple mount ring will do without shimming.
The trigger can be ordered with a wide variety of different trigger blades on a bundle price (they can be ordered later on full price here: FlexiPoint spare blades).
Offset 0-10mm to both sides. If you need a trigger with more offset (up to 46 mm!) and much more adjustment options, check out my Flexipoint trigger.
NEW DESIGN: The MK5 version of the well known FolloWing and SteadyWing systems.
These parts are actually the very same as the upper wings of the Scorpion MK5 FT Hook, and have a massive adapter that connects them to the original hook.
High quality laser sintered Nylon, polished and dyed ‘carbon black’ finish, stainless steel bolts and nuts.
Lightweight structure with a lot of adjustments
All adjustments are available even in shooting position
The links can be bent and twisted, too
Engraved marks for all adjustments – you can record and reproduce your settings any time
Rounded link elements – gives a smoother fit when the links are twisted
Fully re-designed system, with a massive cogs style connection instead of the weak link
True L/H version fully mirrored in every function, and now available in all variations
Please contact me with any questions, I can design any custom part or modify the existing ones, according to your needs.
