    510c optic cover.

    Posted by Brian Harlow on Jan 23rd 2020

    The design of this cover is insanely durable and I absolutely trust that the optic I use on my competition rifle will be protected by this cover. The attention to detail in the design of this is very impressive. If you have a 510c you absolutely should have one of these, especially considering you don't get any cover from the manufacturer. Great for keeping debris off your lens, but it also is very durable to protect your optic from drops and bumps. 10/10.
