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 timeĀ 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.
For a perfect solution please see also:Ā FWB Anti-POI-Shift Kit.


Adapter plate for mounting a hook with a certain offset.
Connection to hook: M5 Nyloc nuts, CTC 90mm
Connection to rifle: M5 countersunk holes, CTC 20mm, 70mm and alrogether 90mm
Offset: 20mm or 35mm.
Thick laser sintered Nylon plate, very massive. Polished black surface.


The FWB Anti-POI-Shift Kit stands of two laser sintered Nylon parts, they look the same but they’re a bit different inside:
With stainless steel screws, all secured against falling out. Easy mounting (you’ll have to drill only a 5 mm hole).

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.Ā 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):
The new design Scorpion MK5 hooks are now in stock.


Lightweight cheek piece for any rifle. 39mm high.
Please note that teh top edges are a bit more rounded than on the photos.
Laser sintered Nylon, polished black surface.
Connection: two M5 nuts, CTC 90mm.


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 ā 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.
For combinations with other scope ring features, see Every Possible (And Impossible) Scope Ring Combination.
