Great optic.......when it works - Holosun HS507C-X2 1x 2 MOA Dot Reflex Red Dot Sight

I wanted to give this a good test before I reviewed the sight. I am going to make a very long and frustrating process short. I ordered a 507c, and had it about 3 months. Put about 5-7 hundred rounds through my custom Glock 17 and the center dot went out. All I could get was the ring. Contacted Holosun and they had me send it in and sent out a 507C V2. Process took about 3 weeks in the middle of league shooting. They sent me the new V2 as a replacement. SWEET! Thanks! But......within 200 rounds the dot started going out randomly. 1 shot it's there and the next it's not. Might work fine for 100 rounds, then flicker in and out for 20 rounds. At this point I'm done with Holosun and going back to Trijicon. I never should have left. For now, the optic is just sitting in the box. I will send it back in at some point and just sell the replacement to fund a new RMR/SRO.
