I purchased the EDC RMSC – Red MRS and I couldn’t be happier. Perfect fit, price, and made in the USA, triple win!! The customer service is top notch, very responsive. If you want a quality red dot optic that’s made in the USA and backed by people who know what they’re doing, look no further than C&H.

Once again this company is batting 1000, man I could not be happier with this purchase. Optic is perfect, clarity of the dot is amazing, adjustable, and clean. If your looking at other companies products you’re making a mistake. I will only purchase optics here, because the product you get is league’s above the rest, Thank you again!

Bought the EDC for Sig P938, already milled. The optic fit the RMSC footprint like a glove. Zeroing was quick and simple. I have run about 1000 rounds through the gun. The optic has remained zeroed. The EDC was a major upgrade from the Sig Romeo. The ease of the buttons and the battery tray make life less complicated. The 3moa dot is easy to see. The brightness setting is at 3. The dot is not overtaken by a 1000 lumen light, night time use. Don’t hesitate in buying this optic as you will not be disappointed. I now need to get my Sig P238 milled so I can get another EDC. Age has set in and irons and I don’t agree.

Bought this after my Holosun 407k started having minor battery issues. Optic fit perfectly with no plate of additional milling needed. Worked flawless with my existing holster as well. A little bit bigger overall that the 407k but I like that they put that additional size in the window.
