Aimpoint ACRO P-2

Very good red dot, on a Glock 19 MOS (and the plate mount ACRO). It fits. I didn't change sights for making it co-witness. I'm not sure it is a necessary. P2 must last longer then the G19. Wich may be a part of your legacy ^O^
I baught some CR2032 to carry with the gun (I even carry magasine, silencer and other accessories, so, a small battery is nothing).
Received under the 8 weeks delay annouced. Easily mounted, with thread lock. Easily adjust. You can download the adjusting target on the ACRO site).

I choose it for the possibility of changing the battery without moving it from the gun. And it save your setting ! Plus it is almost indestructible (don't want to test !)

Great product, good seller.
