4. Holosun HS503CU

⁠

⁠

Let me tell you, the Holosun HS503CU red dot sight is a perfect match for my Ruger PC Carbine. It's like they were made for each other. Here's the breakdown:

Specs:

Compact design - keeps the profile of the carbine sleek.

Shake Awake: This is a game-changer. No more fumbling to turn the sight on in low light situations. Just pick up the carbine and the dot is ready.
