After seeing the thread for "any good red dots under $100?" I got real tempted to order a TRS 25 for my flat top AR. Amazon had them for $90 which seemed about the going rate. Of course it requires the use of a riser which is another $12. PSA has the Vortex Strikefire for $120. (red/green dot) and the higher mount for cowitnessing on the AR. Free shipping. This will just be for fun plinking and maybe some informal courses I set up myself. I don't need any eotech and don't plan to "run it hard" per se, so optic snobs need not chime in with how I should save up a mere $300 more and get a "real" sight. Thoughts? Also if you know of anywhere that has these sights cheaper let me know. I have looked at the usual suspects...MidwayUSA, Amazon, Opticsworld, etc. Thanks!
