HOLOSUN ELITE HE510C-GR, REFLEX OPTIC - "GREEN DOT". HOLOSUN's Premium Rifle, Pistol, Handgun, Revolver Optic. Selling brand new @ $850 + Shipping NZ & $877 + Courier & GST (+15%) from Brisbane. Among list of item's I'm selling due to health issues. I had this mounted on a tac, 3-Gun .22, I built (approx 6/12's) & later swapped it out for a variable power, Strike-Eagle optic. This is the 'goto' optic for three-gun, with a big-old open frame & lot'sa glass (.91" x 1.2") to give You a wide site picture and quick target acquisition - The very best fixed-power optic, I ever used & a match-winner. The Holosun HE510C-GR is a large optic, @ 3.3" x 1.6" x 1.8" & weighs 8.3 oz's. Obviously the size, weight are a bonus, in dealing with recoil & muzzle flip. CHOICE of three Reticle (Easy push-button Switch), '2 MOA' Green Dot, 65 MOA Green Circle or Dot in Circle. I deliberately chose a Green-Dot Reticle Array, to optimize low-light conditions (& to take advantage of the two 'NV'- compatible settings) for my favourite bunny-gun & I have eaten my fair share of 'rare-bit', rabbit caserole. It just seemed that everything I put in the killbox, fell-over (rabbit, quail, pheasant). 12 Light Intensity Settings, 2 NV. The Optic has a number of cool features, including a quick-release/quick detachable, side-mounted, toggle latch, to mount/release the optic itself & a dual-power, auto-switching facility between The 50,000 Hour CR2032, Back-Up battery, or Solar Power via the integrated, solar panel. In low light, the Optic switches to battery mode. The Device/Optic is built of 6061 Aluminum, with a Titanium Hood & the housing is finished in multi-layer Black Paint. The optic is rated IP67. My guess is that once You've mounted & calibrated & zeroed the HE510C, You'll leave it alone but I found I could detach it & place it back on/in the same position (a little twink) & the lock-down latch wud restore my previous zero. The unit wud also co-witness with a Vortex 3x Multiplier that I installed with a flip-down lock latch.
