What customers say about "Key Specs"
Burris FastFire 3 (300235) No Mount 3 MOA Sight (Black)
  • It was easy to mount once I was able to remove the factory rear sight and find the right insert. Easy to sight in and holds the dot in place despite the slamming back and forth of the slide.
  • They are rugged and well designed, small scaled but with a large viewing area. Clear optics. Greatly increases your ability to tighten shot groups on target.
  • I installed this on my gen 4 Glock 34 with the Burris dovetail mounts and absolutely love it. Once you get the fastfire sighted in you are set
  • Great awesome it's the perfect set up for me the window is huge and easy to look through with a very light blue tone. With 4 different brightness' for the red dot one will be perfect for you it says it stays on 8 hours so it's nice I never worry about needing to shut it off
  • Small/Compact, lightweight, looks great and most importantly, amazing warranty!! I dropped my Glock on the bench at my range and the glass in the RDS cracked. I sent it back to Burris and they sent me back a new one in the package totally free.
Vortex Venom (VMD-3103) 3 MOA Red Dot Sights
  • I mounted this one using a plate from EGW and it has been working great.
  • THis is the best combination between price and accuracy. An all around great red dot. I mounted it on my Glock 40 GEN4 MOS and its sublime!
  • I mounted the "Vortex" on a Canik TP9 SFX 9mm. The installation was straightforward and very simple.
  • There are no options for reticle of color but if you know that going in you wont be disappointed by the quality of construction.
  • It was clear as day as far as the reticle was concerned in full Florida sun.

What customers say about "Features"
Burris FastFire 3 (300235) No Mount 3 MOA Sight (Black)
  • Both windage and elevation are simple to adjust on the Fastfire 3, and within just a few shots I had it zeroed at 10 yards.
  • Small, several modes, easy to mount and adjust, holds zero, easy to use overall, speedy target acquisition
  • The dot is adjustable in its intensity so you can shoot it in various light conditions or to whatever preference you desire.
  • This is my second Fastfire and I am as pleased with it as the Fastfire II that I already had. Had is sighted in with just a few shots. The auto adjust feature for light level is very good.
  • This thing even has an automatic mode that measures the ambient light and adjusts the brightness accordingly.
Vortex Venom (VMD-3103) 3 MOA Red Dot Sights
  • Features include auto shut off (after many hours) and auto brightness of the red dot depending on the ambient light but you can also adjust the brightness from the Up/Down arrows on the side.
  • It is easy to see in all light conditions and the Auto brightness feature is quite good and allows me to keep the sight turned on for extremely long periods of time.
  • The higher priced units do seem to have a sensor activation feature. This is the only red dot that I have used, but the unit seems like a great value.
  • This is a very well constructed sight but really lacks features. It can also be slightly annoying to turn off with its press and hold programmed buttons.
  • I guess it's missing the motion sensitive power feature, but I really don't care.

What customers say about "Power"
Burris FastFire 3 (300235) No Mount 3 MOA Sight (Black)
  • In other words, if I loose battery power, I can still look through the sight lining up the front post and vertical line (back-up sights) and be almost as accurate! I want at least a couple more!
  • You don't have to remove the sight to change batteries and adjusting the point of aim is as easy as turning the dial using the supplied tool, coin or shell casing.
  • I also appreciate that the battery is easily accessible. No need to remove the sight from the mount. It's a top load/access to the battery.
  • Works Great! Can change the battery w/o having to sight it in again.
  • I have four of these now. Three 3 moa dots for rifles and one 6 moa custom milled into slide on my Glock 36. They are fantastic. Tough, clear, great battery life.
Vortex Venom (VMD-3103) 3 MOA Red Dot Sights
  • Nice top battery feature where you don't have to remove the sight to change the battery like my Trijicon RMR ver.2. So no re-zeroing when you swap out the battery.
  • Has great battery life, the auto on and off is a great feature.
  • Battery life has been fantastic, I turn it on during competitions and do not shut it off until we pack up and leave.
  • Battery is on top vs. some other brands, that need to have the sight removed to change the battery.
  • Battery life is awesome I usually shoot for 5-6 hours and leave it on the whole time and I'm still on the original battery several months later.
  • Threads for battery are very fine. Make sure your battery plate is aligned before threading to close!
