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″

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
Adjustable angle scope pointer (10°–90° to the scope tube, two positions). Fits 1″ / 30mm / 34mm / 36mm / 40mm scope tubes, and needs only 10 mm space on the tube. The top is 11.5 mm above the tube in vertical pin position..
For parallax wheels and click turrets.
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.
New updated ring design is available. The same function but a better looking ring, scope tube protection, bolt/nut secured against falling out.
The 30/34mm new design pointers are available in a ‘Target’ version i.e. with two pointers, one for the elevation turret and another on on the side for the windage turret.
Flat barrel weight for Feinwerkbau / Anschütz rifles. The same weight (79 g) as the original FWB aluminium barrel weight but allows using longer cylinders – it is only 1 mm thick below and above the barrel. Laser sintered Nylon, with stainless steel grub screw. The M6 threaded holes at the bottom allow you to add up to 10 grub screws to fine tune the total weight and its distribution. The barrel weight aligns itself to the dovetail at the end of FWB barrel. It clamps onto the barrel only with Nylon parts so doesn’t scratch the barrel surface.
New: available also for Daystate Griffin, everything the same as above.
New version: Similar for Steyr but longer, with three air stripper plates as well. ComBrella can’t be connected to this model.
Intimidate your opponents with a rifle that looks like a .50 cal sniper gun! ;-)
Now you can have it with the ComBrella shade that can hold a Combro chrony and connects with a bayonet to the barrel weight, keeping the chrony on its place, aligned with the barrel and protecting it from the sunlight.
It can be ordered with a built-in folding windicator, too.

The FWB Anti-POI-Shift Kit stands of two laser sintered Nylon parts, they look the same but they’re a bit different inside:
One of them replaces the original A-clamp and holds only the cylinder and protects the barrel from accidental kicks but lets it free float.
The other one goes to the joint of the air cylinder and the reg. It can be fixed onto the barrel by two symmetrical grub screws that push small Nylon parts to the barrel and thus don’t scratch its surface.
With stainless steel screws, all secured against falling out. Easy mounting (you’ll have to drill only a 5 mm hole).
Elegantly designed stand for your BFTA Grand Prix badge (or other butterfly clutch type badges), so that it can have a worthy place among your other trophies. High quality laser sintered Nylon, polished surface.
Engraved plate with custom text is available as an additional option (please note that this adds 3-4 days to the delivery date).

Precisely adjustable pointer for reading the parallax wheels in different conditions. For temperature shifting scopes, light/dark environments, old eyes etc.
Fits 1″ / 30mm / 34mm / 36mm / 40mm scope tubes or 42-43 mm ocular tubes for shark fin wheels – and needs only 10×10 mm space in width and length as seen on the picture. With stainless steel screws and steel pins.
This pointer can be adjusted within 20 mm or 30 mm with a thumb screw, allowing precise and repeatable positioning of the pointer. The scale has 2 mm divisions. No need to fix and release, the pin has got some friction so it always stays where you set it with the screw, no accidental move (by your shooting jacket or rifle case).
The adjustable pointer comes with an additional pin 3 mm under the other one, for combining the effects (e.g. use the screw adjustment of the pointer to compensate scope temp shift and use the two pins for light and dark targets). If you need a longer or shaped pin, you can simply replace the original steel pins with any <1mm wire or paper clip.
New updated ring design is available. The same function but a better looking ring, scope tube protection, bolt/nut secured against falling out.
Replacement elements for the FWB P70 Alutec stock, giving new features to the rifle:
Fully adjustable offset grip
Elevating the rear part by 50 mm
Saving 250 g weight
Also the original grip can be used (but without the offset feature). The parts are made of laser sintered Nylon, lightweight but very strong, I personally have tested this kit on my rifle. The new design elevates the cheek piece part so it fits better to high FT scopes. The grip is fully adjustable, and the offset can be set between 7.5 and 22.5 mm.
Right handed, used but in “as new” condition, with some very small usage marks. Can be bought with a ball grip and/or with a grey anatomic grip.
In order to use this kit, you have to cut your original stock, and drill 3 new holes onto it, I’ll attach the technical drawings of all these modifications of course.
I can offer a full FWB collection, please contact me for a discounted price if you are interested in the following products together:
This is a special version of the ‘FT industrial standard’ SmartPin Adjustable Pointer, its long scale (30mm) version combined with the EagleEye Clicks Magnifier for those who don’t have much space on the scope tube.
The SmartPin Combi pointer has one or two magnifier windows for the click turret(s), and needs only 10mm only on the scope tube!
High quality laser sintered Nylon, stainless steel bolts and nuts, Fresnel type 3x mag plastic lenses.
It can happen that you’ll need a stronger or weaker lens (depends on your eyesight), the frame can hold any flat lens up to 0.8 mm thickness or an acrylic lens that is cut to the right shape.
New updated ring design is available. The same function but a better looking ring, scope tube protection, bolt/nut secured against falling out.
Professional folding windicator with orange Nylon cord or alligator clips. Fits to any barrel or air cylinder (with the included adapter), 11mm dovetails, Picatinny/Weaver rails, standard UIT accessory rails, 1″ (25.4mm), 30mm and 34mm scope tubes.
The arm clicks into position when folded in or out (except for the scope ring versions). Ready to use with cable ties / bolts and cord, but of course you can replace the cord any time you like. Unbreakable, flexible, and only 7 grams. Made of high quality laser sintered Nylon, stainless steel nut and bolt.
NEW: also available with new design scope rings. For more features and combinations with other scope ring features see Every Possible (And Impossible) Scope Ring Combination. NEW: all the windicators are available with alligator clips, too. See the options below.
