The new HS507K-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. The HS507K will run over 5 years on a single battery on setting 6, dot only. Featuring Holosun’s Multi-reticle system, the HS507K 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 all of Holosun’s features in one tough, small package.

    This is proving to be a great option for smaller concealed carry guns. It works as it should, is well built, and has a battery that can be changed without removing the sight which is always a plus. The dot is a good useable size.

    Milled and direct mounted on my G48.
