I bought both. Have the K on my Hellcat and have the C on my XDM. This ACSS reticle sight is unlike anything else I’ve used before.

I have the 507c on my prodigy, the 100 yard chevron works surprisingly well (coming from a 5 inch barrel)

I have both prefer the dot on the k vs chevron

I bought the 507C ACSS from Primary Arms for my glock 17 today.

The battery life on the K is MUCH better than on the C. The dashed-line for the outer ring makes a very noticeable difference in battery longevity. The solar-powered aspect of the C is... overhyped. When the battery dies, you'll know it and you'll want to change it. And the 10,000 hour claim must be at an unusably low brightness setting. With both options, it's important to understand that leaving those rings on drains batteries MUCH faster than their standard, non-ACSS counterparts. I love those rings, and I leave them on, but the informed consumer should know that one needs to change one's batteries more often than once a year, ESPECIALLY with the C. I don't see many people talking about this aspect, and then throwing out the numbers for a Holosun standard sight and applying them to these dots, which have 30x the LEDs or something. Yeah, guys, that big glowing ring uses more batteries than smaller rings or reticles that don't have rings at all. Changing batteries on Holosuns is easy, though. Figure out how long your batteries last, then make sure you're always changing batteries more often than that.

GX4 is rMSC print.....🤷

Love my 407k from you guys and love your channel
