The Holosun Enclosed Pistol Sight (EPS) is designed for use on Full-Sized pistols. The Holosun EPS features an extremely low deck height, allowing for the use of standard iron sights for backup on some pistol models. The mounting footprint is the same as the HS407K X2 and HS507K X2 models, with low indexing lugs, thus facilitating the IPX8 waterproof rating and low height over bore.Three reticle versions are available: a crisp 2MOA dot only (EPS-2), 6MOA dot only (EPS-6), or a 32MOA ring with 2MOA dot Multiple Reticle System (EPS-MRS). Other key features include Solar Failsafe (EPS-MRS model only), up to 50,000 hours of battery life, and a Shake Awake Sensor. The EPS will include a 507C adapter plate for use with any industry standard 507C cut slide as well as one CR1620 lithium battery.
