I have a TRS-25 on a 15-22 and have been pleased so far.
They make a
HiRise version which comes with a riser (although not the best looking one in the world), and muted Bushnell logo (gray instead of gold).
You can read my review of it at Amazon (look for basicblur).
I have a few risers from optics-store in multiple heights - I like the OEM looking mounting screw on his, although the picture of the screw on the high riser mount is incorrect - the last two I bought had round OEM style screws as pictured on his low and mid risers.
Low Profile Riser with 3 Slots
Mid Profile Riser with 3 Slots
High Profile Riser with 3 Slots
Be careful with height measurements - I think optics-store measures entire height, while UTG measures saddle height (think you have to go one size taller with the optics-store units to match UTG's saddle height).
I think the tall riser from optics-store matches up with the OEM Bushnell HiRise unit, which will give lower 1/3 co-witness. If you want absolute co-witness, drop to the mid size riser.
If you have a fixed front sight, you may prefer lower 1/3 co-witness. If you have a folding front sight, you may prefer absolute co-witness. Lower 1/3 would mean you don't have the fixed front sight and the red dot on top / near each other, but in order to use the iron sights, you're going to have to change your cheek weld slightly (scrunch down a bit).
With absolute co-witness and a folding front sight, you don't have to worry about sight clutter (assuming you normally run with the front sight down) - if your red dot goes down, when you go to the front sight you will be using the same cheek weld as you were with the red dot.
Here's another option?
I have one of
Bushnell's Throw Down PCL's on backorder from SWFA Outdoors.
They are in every Walmart I've visited recently, so you can check them out there.
I've got a feeling Walmart had first dibs on X number of scopes, and until their order is satisfied, other sellers are going to have to wait on their first deliveries.
I was thinking about a Leupold VX-R Patrol, but after buying my first variable power scope a few months back, found the BDC reticle values change depending on power selected - to me, that really sucks - had to go to school on
first focal plane vs. second focal plane reticles, etc.
I decided to give the Bushnell a try, since it is a first focal plane reticle (BDC values remain constant no matter power selected) and the Leupold was second focal plane reticle.
The reticle on the Bushnell looks interesting / useful? It has an illuminated horseshoe / red dot - you can't see the BDC marks until you up the power level.
Looks like you can use it as a red dot on 1x power (both eyes open), and when you zoom you can use the BDC marks.

MSRP is $419, Walmart is $299, SWFA Outdoors is $237 plus shipping (although I'm signed up for an e-mail alert with somebody for $222 plus shipping).
BTW-the rig I'm running my TRS-25 HiRise on is a poor man's 3-Gun practice rig.
I have a 15-22 with a Nikon P22 scope, and behind it I have the TRS-25 mounted on a
Weaver Offset Rail Adapter.
