Quality not quite there yet - Holosun Red Dot Sight w/ 65 MOA Ring Option

Purchased this optic for my M&P Sport II as the $35.00 red dot it came with was of poor quality. Inserted the battery and the unit activated for a second and then shut itself off. Couldn’t get it to turn back on. Removed/reinserted the battery and it’s been working fine. I thought I would be able to remove the battery tray with my fingernail or a dime after removing the two screws, however, I was required to place a cloth over a pair of pliers to get the battery tray to detach from the housing. There’s also a little distortion in the projected dot as well. It’s far better than the $35.00 red dot I removed but we’re no where near Trijicon or Aimpoint quality. It’s good enough for a practice or Home Defense rifle but not made for battle. 3.5 star product on line with Burris and Vortex.
