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

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
Folding bipod, made of quality materials. Body: black or silver anodised aluminium alloy, legs: 5mm stainless steel with 20mm black plastic balls.
Long legs (12.5cm = 5″ between the ground and the rifle’s stock)
Fits to all rifles with standard accessory rail or similar (AirArms, Anschütz, Walther, Steyr, Feinwerkbau, Hämmerli etc.)
Sorry this product is discontinued but now I have two black ex demo pieces available, been used for a couple of competitions, photo sessions and as a demo when selling other ones on international competitions. In excellent condition, only with a few marks from being mounted onto a rifle. These are the very last ones of the JOPA series.
Simple and lightweight scope pointer. Fits to all 1″ / 30 mm / 34 mm scope tubes, and needs only 10×10 mm space in width and length as seen on the picture.
For 36mm and 40mm tube diameters see EasyPin Extra
For click turrets with a custom made cap, or for sidewheels. With stainless steel screws and steel pin. If you need a longer or shaped pin, you can simply replace the original pin with any <1mm wire. Find out which pointer suits you best: Scope Pointer Comparison Table
NEW: there is an advanced version of this pointer available, too, with adjustable pin angle and also for 36mm and 40mm scope tubes: EasyPin Extra Scope Pointer

Combro Chronies use IR photodiodes as light source so they don’t need external light, but direct sunshine or fluorescent lights may disturb its function, resulting false readings.
This simple shade can be snapped onto the Chrony and gives an effective shade for the light sensors.
The new extended version connects with a bayonet to the Sniper barrel weight, keeping the chrony on its place, aligned with the barrel.

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.
Extra wide bipod for FT rifles. This is not a sniper bipod, its only purpose is to give support between the lanes. FT rifles with their heavy and elevated scopes have a high centre of gravity and need a massive support. The 100mm long legs are wide apart (ball feet 220mm, boot-shaped feet 240mm) so it’s quite hard to knock over the rifle. Update: longer leg versions are available on backorder.
Clearing below the stock is about 80mm. Future versions with longer legs will be available
There are two main variations:
Thumb screw: Connects to all UIT accessory rails with a T-nut and a thumb screw
Quick release: A separate part connects to the stock permanently, either with T-nuts (for UIT accessory rails) or with built-in M5 nuts (for direct mounting on wooden stocks). The bipod slides onto this base part and clicks into its place.
Both variations can have these 4 leg types:
Black Plastic Ball: A simple 20mm black plastic ball with brass threaded insert
Stainless Steel Ball: Solid stainless steel 20mm bearing ball, looks nice shiny and lowers the centre of gravity
FT Caterpillar Boot: Big (25x50mm) curved surface with grooves, a solid support on all terrain, this is a real workhorse and I recommend this for FT
Self-Levelling Flat: 20x40mm flat feet that is self-levelling within ±10°, this is more delicate so it is recommended for mostly dry conditions
