Spotty in being sold out a lot. :-) Quality is excellent! I own several EOTechs, plus Mipros, and am looking at Primary Arms, too. Haven’t tried Aimpoint, but they are tops as well. I just need to remember where I lost it all in that boating accident!
Admittedly they had a great rebate recently when they were sold out. 60-75 rebate....on top of MIDWAY USA coupons. Could not pass that up and bought the optic and the magnifier. I always wanted their magnifier but could never justify the cost.
