One gripe is that it doesn't have a flat end to adjust the rear site like the troy industries tool does. The 2nd one was for an offset troy m4 front sight (yes, it fits perfectly). Took 5 minutes to install and is working perfectly.

The dials are tactile which i appreciate. The brightness adjustments are good enough for my needs.

Cyelee red dot is a great cost-effective option for casual target shooting. Added sight to new * and bore sighter prior to going to the range. Probably going to get one for my rifle soon.

The curler calf xl works flawlessly. The quality speaks for itself. Great sight at a value price.

Great little * optic. Battery try on the side instead of the bottom is wonderful so you can replace the battery without dismounting the optic and then having to rezero it. Top mounted battery compartment is great.

Professional gunsmiths are very adept at mounting this style, if you are not comfortable attempting to install. Mounted to my dagger just fine. Came with all the hardware needed to install it. Can also be used as a suppressor.

When i tried sighting the unit in, that's where things went downhill. Adjusting the sight was annoying. Will not turn off unlesss battery pulled out.
