Strongly constructed - DI Optical FC1 Red Dot Sight

I ordered this sight because it was supposed to be better for people with an astigmatism. Sadly it did work so well for me and my tired eyes. I will say the prisimatic scope did seem to be an improvement. The dot image wasn’t as distorted. I feel that battery listed was a bit short for my liking and the battery tray being plastic was a little cheesy. Those issues aside it’s a well built scope and imo the housing is just as strong as an aimpoint. I can’t comment on the FC-1 overall as I returned it due the above stated issues. If you don’t have the coin for an aimpoint this is a good option as it has actually been military tested.
