What customers say about "Key Specs"

Primary Arms Microdot (MD-RBGII) w/Removable Base

I have 2 of these. I have used them on ARs and 12 ga shotguns. I love them. They just work well. Nice small reticle, no failures, holds zero.
It has a low profile rail mounting base
Seems to be a quality well-made product, reticle is plenty bright even in mid-day sun.
Awesome red dot for the price, this has a very fine reticle and is almost as good as the pricier red dots. Very happy with the purchase.
Compared to the overall size, the red dot window is very small at 0.6 inches diameter.

Bushnell TRS-25 Tilted Front Lens Red Dot Sight Riflescope

The reticle itself is very good at all brightness levels. This red dot is light weight so you dont have to worry about bogging down your rifle/pistol with too much weight.
I figured my old Chinese sks wouldn't, so I sought after an optic that offered quick acquisition within a comfortable eye relief distance and a readily visible reticle that was somewhat representative to a couple MOA red dot reference.
The reticle is very bright as well. The sight has 11 adjustment settings for the reticle but I only needed to go to level 4.
Zero'd it in at 25 yards and ran 500 rounds through it without a single problem Zero stayed right where it should be and the mount was rock solid.
Just so my expectations for this unit are understood, I have this mounted on a Mossberg 500, which is a backup to my Benelli M4 with an Aimpoint T2.
With the 3 I have you can see obvious quality games in the reticle.

What customers say about "Features"

Primary Arms Microdot (MD-RBGII) w/Removable Base

The wind and elevation adjustment screws are easily accessible and click when you turn them to lock in place
It comes with a double cap rubber cover that protects it from dust and scratches and can easily be removed fast
Although I can't complain about the function or features of this Red Dot, I do wish I had spent the extra money and purchased an EoTech.
This optic is great. Many features of much more expensive high end models, without the big $$$ price. Holds zero great, easy to zero, and looks great.
The wind and elevation screws are too big and add to the overall sight size unnecessarily

Bushnell TRS-25 Tilted Front Lens Red Dot Sight Riflescope

The windage and elevation adjustment knobs are very compact as well, each featuring a slot for a coin or other tool to make adjustments.
It doesnt have great features and is pretty straight forward. Red dot isnt the sharpest, but it works great within 50 yards.
Believe me there are more expensive sights out there but for the price I think you get some great features with this one.
After receiving and fiddling with it a bit, I noticed it didn't have a zoom dot feature. I wish the optic was as advertised, I would probably buy a couple more if it was.
Could have an auto shut off feature, but not the end of the world

Battery Life

What customers say about "Power"

Primary Arms Microdot (MD-RBGII) w/Removable Base

The battery is in the brightness selector dial and can be easily replaced
The Aimpoint is built like a tank, has a battery life of years while left on and ready to go at all times, and I have absolute confidence in it.
This works great and battery life so far has been good.
Auto on and better battery life would be nice but you can't beat this for the price. Make sure you have a riser if using this for an ar.
You have to remember to turn it on and off to preserve battery rather than leave it on all the time, but you're also paying a lot less.
Only problem I had is that the battery was dead when it arrived so I just had to buy a new one otherwise its a great quality product.

Bushnell TRS-25 Tilted Front Lens Red Dot Sight Riflescope

It uses the CR2032 battery and I personally have had them go much longer than a year before having to replace them. Just don't use cheap batteries, purchase a reputable brand and you will never find yourself in the woods with your red dot dead.
Battery life is very good for the single button battery the sight uses, just remember to turn it off (set it to 0) when you are done with it for the day.
It doesn't mind the elements and has a long battery life.
Battery life is average at best, and you will drain the battery if you inadvertently leave the light on.
The battery life seems to be adequate. Bushnell claims 3,000 hours.
