Spoiler: It Rocks!
If you buy a cheap red-dot optic you will usually end up with junk that can not produce a bright enough reticle to be seen in bright sunlight, and probably will not be able to handle the constant abuse of firearm recoil.
The Bushnell TRS-25 (pictured above), while not cheap, is still reasonably priced from around $80 – $120 (depending on where you purchase it, and whether it is on sale or not). The TRS-25 has been tested on .375 H&H Magnum rifles. If it can survive that massive recoil, it certainly can handle the almost non-existent recoil of a .22LR rifle.
The TRS-25 has 11 brightness setting. I have two of the red-dot sights and I have never needed to use the brightness settings, even on the sunniest of days. It has a 3 MOA red-dot reticle. Mounted to a Ruger 10.22 I zero the red-dot at 20 yards. Bullet impact at 50 yards is still within the upper third of the dot. Point-of-sight and point-of-impact are the same again at 66 yards. At 100 yards the bullet will impact just to bottom of the dot. With the 20 yard zero you will hit what ever you put the dot on out past 66 yards, and will only require slight holdover as your near 100 yards. My two children can hit spent shotgun shells with impunity out past 30 yards, and tennis balls past 60 yards. I have several friends that have these same sights on their Ruger 10/22 rifles and absolutely love them.
Bushnell makes a riser for the TRS-25 that lets you co-witness with you AR-15’s backup iron sights (BUIS) 1/3 low. Promag makes a mount that will allow you an absolute co-witness with your AR-15’s BUIS.
Note: Make sure that you use LocTite on the screw when you mount the sight to your rifle. Do not over-torque the mounting bolt as you may accidentally crack the mount. Keep an extra CR-2032 battery with your rifle. If you leave the TRS-25 turned on it will not automatically shut off and the battery will probably be dead when you go to use it again.

If mounting on an Ultimak gas tube rail, should you use the high-rise mount on the TRS-25 or the standard mount if you want to use it for the lower 1/3 co-witness option?
JMHO… I wouldn’t use a gas tube rail. Run a class with that rifle and see how hot that gets. If I did use one I’d just mount the RDS low. It won’t be perfectly co-witnessed, but close enough. Then zero it at your distance of choice… discussed on the How To Zero The AK page.
I would love for someone to rapid fire two or three magazines and then measure the temperature of the Ultimak with an infrared thermometer.
How would you recommend mounting a rail on an AK? Rifle Dynamics seems to really like the Ultimak gas tube rail. It seems to get the best positive press.
If Rifle Dynamics says that they are GTG, then they are GTG. Honestly, I don’t have any experience with the Ultimak. I use the Midwest Industries AK Handguard. The gas tube cover does not contact gas tube. On the handguard there are only a couple of small contact points with the barrel, fairly close to the barrel. Doesn’t get hot. https://www.midwestindustriesinc.com/product-p/mi-ak-x-blk.htm
