Those saying that the PROMAX isn't worth the upgrade over the 507 Comp are wrong. The PROMAX has a 20% increased window size over the 507 Comp and in our testing that does make a difference. The sunshade on the front of the optic does a great job removing glare during outdoor shooting. Upgrading to this feels like going from a RMR to a SRO in 2020. We can't recommend this optic enough.

The Holosun 507-PROMAX-RD-PRS is built for maximum visibility and speed, pairing an enlarged performance window with a forward-leaning sunshade to cut glare and keep the reticle sharp in bright conditions.
