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.

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

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

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:
Both variations can have these 4 leg types:

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.

The last couple of old design Scorpion MK4 hooks (R/H and true L/H) are available here: Scorpion MK4 on SALE
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.

A pair of two specially formed adjustable spacers that can connect to each other in four different heights:
Useful for spacing butt-hooks, hamsters and other rifle parts.
Prices stand for a pair of spacers.
LAST ONES!

These items are only spare parts for my trigger system (in black colour only), and allow you to try different surfaces and shapes to make sure, which one fits you the best in practice.

For detailed information please click on the tabs below:
Ball trigger with a 5 and an 8 mm ball on the two ends. Ball triggers are fine because you’ll always have the same trigger weight, but it’s a severe problem that you can’t feel the direction of the pull. If you ask me, you should rather choose a round trigger instead from my standard blades, it’s much better. This Ball trigger is available in Offset version, too.
Small horizontal trigger with pyramids on both sides (fine and coarse). Similar to the ball but you can feel the direction of the pull.
These blades have a big round surface that fits to the fingertip. There are four different surfaces, they look quite similar but each version gives a totally different feel on the trigger, so you can choose the one that fits to your shooting style the best.

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.
