ComBrella shade for Combro
Snap-on shade for Combro Chrony
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.


Barrel Weight 19.91mm
Genuine Feinwerkbau P70FT barrel weight, may fit other rifles, too (please check the diameter of your barrel before ordering).
With an extra M6 hole for a windicator.
Aluminum, 77g and the inside diameter is 19.91mm


Folding Windicator / Alligator Clip
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.


Sniper Barrel Weight
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.


Barrel Weight 17.22mm
Genuine Walther LGR barrel weight, may fit other rifles, too (please check the diameter of your barrel before ordering).
Steel, 271g and the inside diameter is 17.22mm.


TrueLevel Adjustable Bubble Level
Get your rifle into a true level with these adjustable bubble level bases: you can fine tune its angle and eliminate canting effects.
It comes complete with a bubble level and connects:
- to the rifle with a standard dovetail (10mm wide at the neck but the material is easy to carve if needed), or
- to the scope with a 1″ / 30mm / 34mm ring.
Please check before buying that there is enough space for this part on your rifle. The rings need a 10mm wide spece on your scope tube, and the dovetail based unit requires at least 25mm above the top of the dovetail.
New updated ring design is available. The same function but a better looking ring, scope tube protection, bolt/nut secured against falling out.
