Ok optic but can be better - Burris AR-536 Prism 5x 36mm Tactical Red Dot Sight, Ballistic CQ Reticle

I purchased this optic for my 16" Colt M4 Carbine build. I noticed that the the alignment of the reticle is slightly canted, but it's not that bad and I can work with it. I think Burris can refine this product a little more, especially the reticle design and alignment. Also, the center dot obscures smaller targets from 100 yards away. A smaller center dot would help mitigate that issue since this already has a fixed 5x magnification. Other than that, it's not a bad optic and does the job just fine. The eye relief isn't bad either and a bit better than the acog, but it's still somewhat a bit too close for comfort for me... an extra inch on the eye relief would be perfect. It would also be nicer if the magnification isn't fixed at 5x and can be dialed down to 1x, but at least it has rails where you can attach a 1x red dot sight on for CQB purposes.
