I know that I am late to the party, but I am a KISS kind of person. I have been on the side-lines reading and rereading everything I could find until I felt comfortable giving the dot a try. As previously stated, I got a 508T X2 green and mounted it PSA Dagger RMR cut slide. I figured I could put the 508 on an AR if it did not work out and the Dagger slide was only 125 bucks if the experiment did not succeed.
All I can say is all my fears were put to rest yesterday.
It took me about seven rounds to get sighted in a 10 yards. After I got the dot to hit where I was shooting, I put five rounds into a single hole. I did shoot supported for sighting in and then confirmed using normal shooting positions. I am glad I got the green dot as it was easy to see at high noon in the Mojave desert. I also don't have the astigmatism issues of dots on rifles. Maybe because it is farther from my eye, but the starburst is minimal compared to a dot up close.
Drawing and finding the dot was not as hard as I thought it was going to be. I need to keep working on this but am off to a good start.
For the first time ever I was able to get a sort of group at 50 yards on my 2/3 silhouette. I can hit is pretty easy with irons, but they are all over the place. 75 yards was almost automatic as well. I was shooting supported, but all I had to do was put the dot on the target and press to get hits. At 100 yards I was able to get 9/10 rounds on the silhouette.
I have a lot of work to do to get where I want to be, but right off the bat I am impressed.
Anyways here are some pictures to keep the thread from being useless. I was texting my buddies these photos, so sorry for the mark-ups.
