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.
Trijicon RMR Type 2 6.5 MOA LED Red Dot Sight
  • Fitted perfectly to G-19 gen 4 slide. 6.5 dot is good; easier to center in view than smaller dot and easy to see in day light.
  • Is everything I expect to receive very clear I really appreciate that it's automatic.
  • Amazing. Fantastic for Close quarter combat. This unit is mounted onto an ACOG and provide very fast acquisition of targets within 50 yards. Beyond that, I use the the ACOG.
  • Put this on my Gen4 Glock19 MOS and ran 300 rounds through it with no issues. Accuracy is incredible.
  • The reticle to me is a little fuzzy. It is somewhat large at 6.5 mils but I had more than one person tell me that is exactly what you want on a pistol to aide in quicker target acquisition.
  • Good product. The 6.5 MOA dot was just a little large for longer range shooting. Swapped this out for a 3.5 and it was fine.

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.
Trijicon RMR Type 2 6.5 MOA LED Red Dot Sight
  • Auto brightness works well without having the added need to manually adjust. All very good for older eyes.
  • BETTER than expected performance on a handgun. SUPER durable & low profile for CCP.
  • Variable brightness is a plus for different lighting situations. No problems finding the red dot for me. ACOG is zeroed at 100 yards. RMR is zeroed at 25 yards. So happy wit this product that I bought one to mount on my Glock.
  • Went on my glock 10 mm,using adapter plate recommende by trijicon woked great !!
  • Great product when it works. Turns on and off when it feels like it. T's customer service and I have become best friends - heck I even have them programmed into my phone.
  • Red looked like a dot with splattered light surrounding it and i had trouble centering the red dot both on elevation and windage on gun that is competition optic ready by by smith and wesson.

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.
Trijicon RMR Type 2 6.5 MOA LED Red Dot Sight
  • 18months in auto brightness on 24/7, battery is still going strong.
  • The fact that the sight is always on for four years and runs on only one battery is pretty fantastic too.
  • This optic is rated to run for years of continuous operation at brightness level '3' on a single battery. Awesome.
