I have the Vortex Strikefire red/green dot on my MOE, and I found that I can hardly use the green at the indoor range I shoot at.
For kicks I have been researching the smaller Vortex Sparc, and also the PA Microdot.
I just placed my order for the PA, and here is what I ordered:
Code Item Qty Price Grand Total
MD-07 Primary Arms Micro Dot With Fixed Base
[AR15 Mount Options:Leapers UTG Medium Profile 3-Slot-Abs CoWitness Picatinny Style Riser] 1 $84.99 $84.99
^ MNT-RS08S3 Leapers UTG Medium Profile 3-Slot Compact Picatinny-Style Riser Mount AR-15 Flattop Matte
1 $0.00 $0.00
I went with the true co-witness, and the guy I spoke with said I could either go that way or with the 1/3 with my Magpul MBUS Gen II sights.
Should be here mid week I hope.
This was also 1/2 price of the Sparc, and I was almost going to pick that up after work today from an AR15 shop in my town where I got the Strikefire with, but I decided to go ahead and try the PA since a lot on here rave about it, and the YouTube reviews look good too.
Wish it had flip up caps instead of the bikini, but the guy I talked to said not enough material on the tube to do that.
I also find the flip up caps on my Strikefire to be very hard to close.
