5 reviews for Holosun 507k X2 Green Reticle

    Ordered this Holosun 507k along with the SIG P320 RX / Pro Series / AXG to Holosun 407k / 507k mounting plate, which fit my Sig 320 Xcompact perfectly. No overhang on the sides. The mounting plate is thin enough factory irons are still useable. The circle dot sight makes for quick acquisition and great fast recovery for follow up shots. CHPWS was the best place to order and pricing was below most other online retailers. Highly recommend this sight, and CHPWS.

    Of all red dots I’ve used this is the most enjoyable and dependable one yet. Love the green display and circle and dot sight pattern. My red dots have more blur to them due to astigmatism, but with the green there is a noticeable difference. The battery tray is great and will save time when the battery needs replacing. The mounting plate fits perfect. They even send you the thread lock for the plate screws. I carry the Hellcat Pro and with this mounting plate and reticle, I carry with confidence in my sighting at the range and if needed in personal defense.

    I am more than elated with the entire experience with CH Precision Weapons. I purchased and adapter plate and Holosun 507k X2 Green Reticle for a S&W M&P Shield Plus. The experience was great from the initial call to them to the delivery of my order, to the customer service afterwards. Not only were they professional, engaging, supportive, and knowledgeable during all phases of my purchase, but they were friendly.

    As a result, I have referred a couple of customers to CH Precision Weapons, one of them, Mr. Speiths, who gave me his permission to use his name in this review,

    I received the proverbial “run around” with a local shop, which was quite frustrating, but just one call to C+H solved my issues. Moreover, I saved even more, due to the support from C+H, from a phone call to them, and using their videos to install the plate and optics myself. As to the savings, everything I purchased from C+H costs less than what the local shop charged.

    It’s unfortunate that all experiences with vendors are not at the level of service provided by C+H Precision Weapons.

    Ordered this to get a low-profile dot sight instead of mounting on the rail of my Ruger Mark IV 22/45 lite. It looks and operates really well. The green dot is just as good as the red dot variants I have used before.

    Had the swampfox auto in green initially, wasn’t a fan of it due to losing my iron sights window and I couldn’t get a clean dot (possible astigmatism). Got this with their plate and it was night and day. The plate has the recoil lugs in it still to fit into the 507K footprint. I still have useable iron sights. I keep this right about in the middle of the brightness adjustment and it seems fine both night and day without adjustment. Would maybe need to go higher brightness in very bright light, but no big deal. Only issue you may run into is if you use the sight to rack the slide you may bump the brightness higher. Both the sight and the plate are fantastic. Very happy with the whole setup.
