Default RDS Fit?

How can I mount this RDS on my AR15 M4 flattop receiver?
Sounds like a good deal!

It will mount the way it is, or if you want it up a bit higher use a riser. The mount is part of the RDS unit.

With the rebate that's a great deal on a pretty good RDS. I have two TRS-25s and have had no problems with either. Was afraid recoil would cause the dot to drift but that hasn't been a problem.

If you get a 1" riser you can get a perfect cowitness with your MBUS rear sight and F-marked FSB. I went cheap on two UTG RS10S3 risers thinking I'd replace them with something better but was surprised to see they're tough and hold zero fine. They seem to do the job but I still don't like the idea of UTG on my ARs.

If an Aimpoint or EoTech isnt in the cards Id go this route.

The Primary Arms Micro is a great choice and I like that you can add their riser to your order. A little more money but a better choice. I admit I went cheap on optics, with the intention that I'd move the Bushnell to my "tactical .22lr AR" if it didn't work out. So far I've been pleasantly surprised. And of course I do have BUIS after all!

Back Up Iron Sights, like your MBUS!

If the cheap RDS fails you rip it off, flip up the MBUS and keep in the fight...

Or you can still look through the RDS tube as a ghost ring.

RC,

Unless I am not thinking correctly. You just mount it directly to your picatinny rail on the flat top in front of your flip up BUIS rear sight. The screw at the bottom of the unit is the screw that controls the clamping system on the bottom?

Just got my Bushnell TRS-25 from Amazon.
Totally disappointing since the dot is not a dot but a jagged, red thing.
Anyone had this problem?
