The new HS507C -X2 Micro Red Dot System from Holosun is a pistol-sized optic with an open frame for a great sight picture, clear glass and a rugged 7075 aluminum housing. It is powered by a CR1632 battery and Holosun’s innovative Solar Fail-safe back up. The HS507C X2 will run up to 5 years on a single battery on setting 6, dot only. Featuring Holosun’s Multi-reticle system, the HS507C allows the operator to switch the reticle between a 32 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 32 MOA ring only, all at the push of a button. Better yet, the same LED projects all three reticles, so no re-zeroing is necessary. It comes equipped with Holosun’s Shake Awake technology with last setting recall. This optic has Holosuns features in one tough, small package. Fits RMR mounts and milled slides.

Pricing is on point for a great deal. I have a few different MRDs and I enjoy the holosun for the reticle and the ability to swap battery without losing a zero. Great product and price

No complaints on this optic, assay install, holds zero, long battery life, easy battery change without having to remove it from the slide

My favorite of all of the Holosun options. I really dig the green over red. BTO always has them in stock for a great price and fast shipping!!!

Got the red version. Looks/fits great on my Brownells RMR cut slide. I am using the circle and dot reticle and it is awesome. I like the shake awake function because it is mainly sitting in my gun cabinet and I know that the battery will last a long time.
