I own a SIG P365 XMACRO Comp that I topped off with a Holosun 507K with ACSS reticle. This cover is a tight fit with the suppressor-height sights I have on the firearm, but anything is better than nothing to protect your optic for storage or transportation from debris or gun oil. I hope these become available for my other red dots that don't ship with covers ie. Trijicon RMRs.

Holosun 407K & 507K Optic Cover - Precision Fit, High-Quality Soft Rubber Protection - Dust, Scuff & Scratch Resistant

Dust cover arrived in short order and fits like a glove. I've had others that tended to fit loosely and would fall off, but this one is snug and stays in place. Thanks!

Put this optic on a 9mm FN for my wife. She loves it.
