My go to optic brand other than primary arms - Holosun Paralow HS403B 1x20mm 2 MOA Red Dot Sight

Optics planet is my preferred optics shopping experience and Holosun has never done me wrong. The red dot is easy to zero and hold zero perfectly. The shake feature on Holosun optics is excellent.. my fire arms that host Holosun optics are, Smith and Wesson FPC 9 mm pistol, caliber, carbine, river, 1022 takedown with Magpul X 22 backpacker stock and my 5.56 Caltech RB Bullpup sported the solar powered red dot but I have recently changed that out to a 1x prism ACSS reticle primary arms, and I still have my three time magnifier behind that from Holosun.
