Red Dot or Green Dot Sight - what one is best for you?
A regular question we are asked at Tac scope HQ is what colour dot to choose. Of course some models have both but if you are setting priority on one what do you need to consider?

When to Use a Green Dot Sight:
Bright Conditions – Green is easier to see in daylight because the human eye is more sensitive to green wavelengths. This makes it ideal for outdoor use in bright environments.
Eye Fatigue Reduction – Green is less straining on the eyes, especially during prolonged use. If you plan to use your sight for extended periods, a green dot can be more comfortable.
Better Contrast in Certain Backgrounds – In environments where red may blend in (such as wooded areas with brown or red-toned backgrounds), green can stand out more.
Astigmatism or Vision Issues – Some people with astigmatism see a red dot as blurry or distorted, while a green dot appears clearer and sharper.With this issue also look into Prismatic scopes that can solve the blurrya nd distorted problem but at the cost of having to accept regular eye relief.
Battery Efficiency at High Brightness – Green dots often require more power at high brightness settings, but some modern optics optimize for this, making them practical even with the higher energy draw.
When to Use a Red Dot Sight:
Better Battery Life – Red LEDs are generally more power-efficient, so red dot sights last longer on a single battery.
More Night Vision Compatible – Red dots work better with night vision because they can be dimmed to levels that don't overpower night vision devices.
More Common & Affordable – There is loads more choice in red dots and they are usually cheaper than green dot sights.
Apart from Night Vision the common availability is the biggest factor, there are not many green dot models about. See below for some ideas.
Conclusion:If you're shooting in bright daylight or have trouble seeing red, a green dot sight might be a better choice. If you need longer battery life, night vision compatibility, or a more budget-friendly option, a red dot is still a solid pick.
Example: For a rifle. NB - we stock Holsun, Vortex, Vector and Hawke. Use the search funtion and write Green Dot to bring up options.
You'll want a durable and reliable red/green dot sight with good battery life and a clear reticle. Here are some top recommendations based on performance and budget:
High-End Holosun HS510C – Best OverallWhy? Extremely durable, solar backup, long battery life, wide sight picture.Features: Red/green reticle, shake-awake, multi-reticle system.Best For: AR-15s, tactical carbines, hunting rifles.

How to make an homemade Honeycomb Sunshade Killflash ARD
One of our regular enquiries is if there is a honeycomb sunshade or killflash/ARD for a particular scope model. They can be useful for reducing glare and preventing reflections from optics such as scopes, binoculars, or red dot sights
Unfortunately in most cases there is no after market accessory. Such things are nornally screw in and are very fussy about specific make and model scopes both in case inner diameter and then thread pitch and width. Taking the example of Hawke honeycombs, they do 2 models for just their 50mm scopes, due to differences in case inner diameter between AO and non AO models. And even then they do not fit a lot of Hawke scopes, especially older models, let alone anyone elses! Such is the issue that we have taken them off sale on places like Amazon where we cannot edit adverts to stress the importance of 100% compatibility. = Many returns.
But all is not lost! From low tech supermarket to higher tech 3D printing there are ways to make your own. Here are some ideas for your new DIY honeycomb shade.
A homemade honeycomb / killflash (anti-reflection device, ARD) You can make one using simple materials like honeycomb material, plastic, or mesh.
Method 1: Drinking Straws (Easy & Cheap) Materials Needed:- Black plastic drinking straws (thin-walled preferred) - Super glue or hot glue - Electrical tape or shrink wrap - Razor blade or sharp scissors - A scope lens cover or plastic ring
Steps:1. Cut the straws to match the depth of your scope's objective lens (typically around 5-10mm). 2. Arrange the cut straws tightly together inside a plastic ring (use a scope cap or make a ring from a bottle cap). 3. Glue the straws together carefully to form a honeycomb-like structure. 4. Trim excess material to ensure a perfect fit inside your scope’s lens housing. 5. Attach the ARD to the front of your optic using electrical tape or glue.
Method 2: Honeycomb Mesh (More Durable)Materials Needed:- Black plastic or aluminum honeycomb mesh (found in car grilles, air vents, or online stores) - A scope lens cover or a plastic ring - Super glue or epoxy - Sharp knife or Dremel tool
Steps:1. Cut the honeycomb mesh to match the size of your optic's objective lens. 2. Secure it inside a lens cap or within a plastic ring that fits snugly. 3. Glue or snap the honeycomb insert into place. 4. Paint matte black if needed to reduce reflections further.
Method 3: Window Screen or Metal MeshMaterials Needed:- Fine black window screen or metal mesh - Scissors or wire cutters - Glue or double-sided tape - Black paint (optional for extra anti-glare protection)
Steps:1. Cut the mesh to fit over the lens. 2. Glue or tape it to a ring that fits on the objective lens. 3. Use multiple layers if more light reduction is needed.
Final Tips:- A deeper honeycomb (5-10mm) will be more effective at blocking reflections. - Ensure uniformity so that light transmission is not blocked too much. - Test the ARD to ensure minimal distortion of the sight picture. - Consider using removable methods like Velcro or friction-fit rings for easy removal.
Here is an example for a specific optic. In this case a Vector Optics Mustang 1-4x30 is a low-power variable optic (LPVO) with a 30mm objective lens. Given its compact size, a homemade killflash (ARD) needs to be slim and lightweight to avoid obstructing the field of view.
Best DIY Killflash for Your Scope: Recommended Method: Honeycomb Mesh (Durable & Low Profile) Since the 30mm objective is relatively small, using a thin aluminum or plastic honeycomb insert is the best option.
Materials Needed: ✅ Aluminum honeycomb mesh (from car grilles, ventilation panels, or Amazon) ✅ 30mm plastic ring (scope cap, PVC pipe section, or a 3D-printed ring) ✅ Super glue or epoxy ✅ Matte black spray paint (optional for extra anti-glare protection)
Steps: 1. Cut a 30mm circle from the honeycomb mesh (about 5-7mm thick for best results). 2. Insert it into a scope cap or plastic ring that fits snugly over the objective lens. 3. Glue the honeycomb piece inside the ring and let it dry completely. 4. Paint matte black (if needed) to further reduce glare. 5. Attach it to the front of your scope using friction fit, Velcro, or a small amount of removable adhesive.
Would you like a 3D-printed design template or help finding materials online?For this, get on over to ChatGPT or your AI of choice and ask it: how to make an homemade honeycomb sunshade killflash / ARD for *scope make model here*It will reply with the options above and then ask if you want it to generate design templates. Amazing.
For our example 30mm scope above here is what to expect:
solid Killflash
// Define parameterslens_diameter = 30; // Diameter of the scope lenshoneycomb_size = 3; // Size of honeycomb cellsthickness = 7; // Depth of the killflash
module honeycomb_pattern(){ for (x=[-lens_diameter/2:honeycomb_size:lens_diameter/2]){ for (y=[-lens_diameter/2:honeycomb_size:lens_diameter/2]){ translate([x, y, 0]) cylinder(h=thickness, r=honeycomb_size/2, center=true, $fn=6); } }}
module killflash(){ difference(){ // Outer ring cylinder(h=thickness, r=lens_diameter/2, center=true, $fn=100); // Honeycomb pattern honeycomb_pattern(); }}
killflash();
How to Use the File:Download & PrintUse PLA, PETG, or ABS (black recommended).Print with a layer height of 0.2mm for best detail.
Post-ProcessingSand edges if needed for a snug fit.Paint matte black if necessary.
AttachmentSnap onto your scope or use a small amount of removable adhesive.

What To Do If Your Night Vision Scope Freezes
A common email or call we get relates to a digical night vision or thermal scope freezing up. Not turning off. Not functiing as it shold be and so on.
It is not unusual and actually you should expect it sooner or later. Do not panic. It does not mean in nost cases the the unit is faulty and needs repair or replacement.
Remember this - Night Vision and Thermal scopes are basically computers in scope form, and as you do at home, or get told to do by the moody IT tech at work - Reboot it!
So you use a similar approach as when a computer or phone freezes.
1. Force Shutdown i.e. reboot - - Press and hold the power button for 10–15 seconds. This should force the unit to turn off.
2. Remove the Batteries - If holding the power button doesn’t work, remove the batteries from the device. Wait at least 30 seconds before reinserting them and turning the scope back on.
3. Check for Firmware Up dates - If the device keeps freezing, check for a firmware update on the manufacturers official website. Install the latest firmware using a microSD card (follow manufacturers update instructions).
4. Contact support - If order placed with Tacticalscope contact our parent company Opticswarehouse, though to be honest, they will probably suggest the above and if fails send in for inspection. Call them on 01803 611895

What Red Dot Sights are Suitable for Weihrauch HW44 Pistols
We are often asked what sort of sight or scope is suitable for "model" rifle or pistol - Or is the "model" sight suitable for "model" rifle or pistol.
Here is an example that I thought would make a useful post that helps guide the decision process even if not specific to you.
HACK TIP - Ask Chat GPT or other AI in this format and you will get a very good answer: SCRD-19II Vector Optics Is this red dot sight suitable for Weihrauch HW44 PCP .177 Air-Pistol, for use in the following scenarios; Target shooting on ranges, and outdoor pest control @ 10/20/30m
And here is what the robot gods had to say:
The Vector Optics SCRD-19II (Frenzy 1x17x24) red dot sight is a compact, lightweight optic that can work well with air pistols like the Weihrauch HW44 PCP .177, provided it meets your specific needs. Let's evaluate its suitability for target shooting and outdoor pest control at 10/20/30m.
Get one here (if in stock)
1. Compatibility with Weihrauch HW44
Mounting: The HW44 features a Weaver/Picatinny rail, which the SCRD-19II should fit without issue.'
Durability: The SCRD-19II is designed for recoil resistance, and the HW44, being a PCP air pistol, has little to no recoil, so it should hold zero well.
2. Suitability for Target Shooting (10/20/30m)
Dot Size: The sight has a 3 MOA red dot, which offers a good balance between precision and fast target acquisition. At:
10m → The dot covers about 9mm of the target.
20m → Covers around 18mm.
30m → Covers about 27mm.
This means for precision target shooting, particularly for smaller targets, the dot may cover too much of the bullseye at 30m.
Brightness Settings: The SCRD-19II has adjustable brightness, making it suitable for different lighting conditions, whether indoors or outdoors.
3. Suitability for Pest Control (10/20/30m)
Accuracy: At 10-20m, the 3 MOA dot should allow for accurate shot placement on small pests like rats or pigeons. At 30m, it may start to obscure finer aiming points, making headshots on very small targets challenging.
Parallax & Eye Relief: Being a red dot sight, it provides unlimited eye relief and is parallax-free beyond a certain distance, which helps for fast, instinctive shooting.
Conclusion: Is it Suitable?
✅ Yes, the Vector Optics SCRD-19II is a suitable red dot sight for the Weihrauch HW44 PCP .177, especially for target shooting at 10-20m and pest control at close-to-medium distances.???? For precision shooting at 30m, the 3 MOA dot may be a bit large, but it depends on the size of your target and your shooting preference.
Alternative Considerations:If you want more precision for longer ranges (30m+), a smaller MOA dot (e.g., 2 MOA) or a scope might be better.If your priority is fast target acquisition, this red dot sight should work well.
