Sightmark Ultra Shot A-Spec Refl... vs Streamlight 69280 TLR-6 Tactic...

Parallax is good and overall quality appears top notch. All perform flawlessly. Not a deal breaker for the price.

The qd mount, while not of the locking variety, sits very tight on the rail and flush with the sight and weapon. Elevation/windage corrections screws are recessed slightly into the sight body to prevent inadvertent change.

Since i honestly can not believe there are people out there with firearms who think out the box throw reticle has nv night vision.

Probably would make no difference in hight light situations. If you sight this in and move your leaver to change optics it will no longer be sighted in. The nv function does not work.

Super easy install and they seem to be very sturdy. A very modular set up for fast and easy install.

Fit is perfect, quality is top tier. It fits very snuggly to the trigger guard as well. Multiple holsters and cleanings. It is just as snug as the first day.

It fits my glock 43x perfectly. The lumens or what to expect from a small light. Fit both my glock 42 and 43x, real bright.

Streamlight customer service is worthless. Makes me hesitant to buy more of their products. Same issue.

The battery life of this light is very limited. When in momentary on, if i ease up on any amount of pressure the light just turns off. I have to order special lithium batteries from amazon to get the light to work.
