This collection contains Holosun 507 series red dots for pistols. The 507 models have the Multi-Reticle System: a 2 MOA dot, a 32 MOA circle, or both. The 507C and 507 Comp use the Trijicon RMR footprint, the 507K uses the Holosun K-series footprint.
507C X2: red or green, with Solar Failsafe and Shake Awake.
507 Comp and 507Comp: a larger 22.1 x 27.9 mm window for competition. The 507Comp has a side battery tray.
507K X2: the small version for slim pistols.
To mount the red dot on a pistol with an optic cut, you need a plate with the same footprint. See Optics ready plates. For all Holosun red dots, see Holosun.
