6 ADE RD3-006x Green Dot + Rear Sight Optic Mounting Plate/Adapter for All Glock (Non-MOS, Non-Aftermarket Slide) Standard Models, Canik TP9SF and Taurus GX4, G3C & G3 with Factory Steel Sights Pistol

  • This listing comes with ADE red dot, a picatinny mounting plate(pre-assembled) and a pistol mounting plate for Glock that replaces the factory rear sight dovetail of all Non-MOS Glocks from Glock 17 to Glock 43 to glock “100”. Does NOT fit Glock with AFTERMARKET slide with optic cut.
  • The included Glock plate also fit some other Pistols such as Canik TP9SF(does not fit SFX, COMBAT, SA). This Glock plate also fits Taurus GX4, G3C & G3 with factory steel sights (does not fit any other Taurus models such as G2/G2C/G3 without factory steel sight/Tx22/PT111) because those pistols made the rear sight dovetail based on the Glock rear sight dovetail specifications. While it is possible to install this mount without the use of a Gunsmith, we recommend hiring a professional gunsmith
  • We have made several improvements since it's initial release in 2015. We have made it more durable to withstand various recoil and improved the ability to hold zero. Designed in Oregon. The on/off switch is located at the front of the sight, it is so much easier to press than the Red dots has the switches on the side.
  • Shock/Fog Proof. It is rain resistant, but not waterproof. Lenses are precision ground and Polished to exacting geometries to virtually eliminate Parallax and to provide a very clear, crisp sight picture
  • 4 MOA. 5 Illumination Settings. Powered by a lithium CR2032 battery(Included)
  • Why don’t I see a perfect round dot? Instead, I see a splashed dot, half-moon shape, multi dot, starburst etc. Answer: It is very likely (99% chance) you have astigmatism that you are not aware. What you see is a led light image reflected on the lens. One simple way to find out is to use your cellphone to take a photo of the dot. If you see a circle dot in the photo you took, you basically diagnosed you have Astigmatism(Because cellphone is a machine does not has human astigmatism).

How to Choose the Best Sights For Glock 21

With so many sellers out there, it can be hard to decide who is the best one for you. There may even seem like every single person has different requirements! But don’t worry because we’ve got your back – here are seven things that all shoppers should consider before making any purchase:

1. Price

To avoid paying too much for a good product, it’s important to consider the price. If you can’t afford an expensive item and would rather buy something cheaper or wait until there is a promotion on sale then remember that sometimes quality matters more than cost! One thing shoppers need realize though: not everything comes at an affordable rate no matter how cheap prices seem so always read carefully before buying anything new online-you never know what kind of joke someone might be trying to pull where their products’ real value falls short from its wholesome selling points due solely because some unscrupulous company makes use low grade materials while claiming theirs are high end items made by professionals with years experience etcetera.

2. Brand

When it comes to fashion, there is a lot of debate on what brands are worth investing in. Some people think that major or well-known companies have higher quality products because you know exactly how your purchase will turn out if they sell durable goods from time tested designers with established reputable names like Ralph Lauren and Nike Inc., while others prefer buying unknown brands where anything can happen since no one has tried them before so nothing would be lost even if something goes wrong during delivery etcetera. The best way for me personally was going through both sides until finally landing somewhere between these two extremes: buy a recognizable name.

3. Function

What are you looking for in a ? Will the one that suits your needs perform all of these tasks like a pro and with ease. If it doesn’t, then don’t buy into its claims! Check out product descriptions carefully because sometimes companies modify products to cater different customer demographics or target markets – so make sure when buying anything new from them, even if they say “exactly what I wanted!” All this means is paying attention; always do some research before making purchases.

4. Customer Reviews

One of the best ways to find out if a purchase is right for you in terms of product quality would be by reading through customer testimonials. You should look at both positive and negative reviews so that they can give all benefits as well side-effects when purchasing products online like this one, – For All Budgets!

5. Pros and Cons

If you’re uncertain if your purchase is worth the cost, consider all of its benefits and drawbacks. Is this product going to provide me with what I want out of it? Or am i simply buying into something because other people think its great too (based on reviews)? You could also look at a description or even customer feedback when brainstorming pros/cons. If we carefully weigh these aspects before making any final decisions regarding our purchases then hopefully everything will turn out perfectly in due course!

6. Service

You should always read the company’s policies when buying items. Make sure they’re reliable, and if something happens down the line- will you still be able to get help?

7. Warranty

In the end, a warranty is important for any major purchase. However it’s especially critical with expensive items because you can’t afford to buy an item again if something goes wrong within one month of owning them. If there isn’t even confidence in quality from manufacturers after selling products then consider their unwillingness as reason not too trust them and jump ship before things get worse!
