I tried BSA, ultra dot and several others. I like the center point! I got it from optics planet! I just won 1st place 3rd in a row league with it! ( average is 459, two were 469 out of 500 for a 10 week shoot ) It has a small dot, red or green and is variable. The parallax is almost 0! If I bench the gun and move my eye the dot stays on target at 50 ft even at the edges of the optic glass! I usually just barely turn it on so its very low and looks the smallest! At 50 ft the dot just fits in the 10 rung on a B2 target! I guess its a 2.5 MOA at that distance unlike most of the 5 MOA and even smaller than the ultra dot. I got an ultra dot and had to send it back because it had some junk floating in it. So they replaced it and would not refund it. So I have a new one here that I dont use and dont like! Amie
I forgot to mention I had a friend of mine who has a gun smith shop drill, tapp and put a waver rail on the stock target barrel, Usually I use my TSOL 8" pac lite barrel and had it include the tactical rail. I also use the blue lock tight because the screws DO come loose!
