well I just got fire my PS-90 with my new USG black reticle, The 1st 6 rounds I fired were center mass but off to the right a bit. I only had to make one 1/4 turn adjustment to the windage, and boom dead on target. Zeroing was done at 50 yards, and then i fired all 200 rounds of ss 197 i brought with me at a 2 foot by 2 foot steel target at 100 yards standing up. Nothing is better then having both eyes open standing up and hitting the target with every round. Point blank this sight kicks azz I am happy I got it. Not to mention the price I got it for 355 dollars with a 30 to 50 round converted plate (the guy a purchased it from wanted my factory sight in trade, lol take it!!!). All I have to do now is wait until payday and send in my Form 1.
