Every few years I go through my guns and update optics. Right now I am looking to upgrade the red dots on some non hard use guns- three S&W MP15 .22s', a Browning Buckmark .22 pistol, a 10/22 SBR etc.......These guns have either Bushnell Trs 25's- most of them, or a few I think have original Vortex Sparc's. The TRS25's were great little optics 10 years ago, inexpensive and mine have never really given me any issues BUT they are not very bright in full sunlight and have some age on them- You can only expect so much of inexpensive optics and I want to cycle them out before I start having issues with them. Also, I would like to standardize on one design as much as possible.....

Looking to spend about $150 apiece or so on replacements. Thinking Primary Arms, Holosun or Sig Romeo's...... What's the best of the 3? Honestly, they appear pretty much identical and I suspect some if not all of them are made in the same Chinese factory.......
