Holosun EPS Green 6 MOA Brilliant Enclosed Low Deck Sight

Description

The Holosun EPS Green 6 MOA is the enclosed pistol sight with a single green 6 MOA dot at 540nm. Sealed emitter, aspheric lens, ultra low deck height, 1.4 ounces, and an RMR to K adapter plate in the box. No circle, no reticle menu. Part EPS-GR-6.

Which EPS Is This One

Holosun sells six sights under the EPS and EPS Carry names including the Holosun EPS Green 6 MOA and they are genuinely different, so here is exactly what you are looking at rather than a part number to decode.

This is the full size EPS, green, with a 6 MOA dot and no circle. Its siblings are the same housing in red and gold, the 2 MOA versions with a finer dot, and the MRS versions that add a 32 MOA ring you can switch on. The Holosun EPS Green 6 MOA is the combination for a carry gun: the fastest dot size to find, in the colour that holds contrast against the backgrounds a defensive pistol actually meets.

Six MOA Is A Carry Decision

The 6 MOA dot on the Holosun EPS Green 6 MOA covers an inch and a half at twenty five yards and six inches at a hundred. Against a 2 MOA dot it gives away precision at distance and buys speed up close, and for a defensive pistol that is a trade most shooters should take.

The larger dot is quicker to find on a draw from concealment, easier to track through recoil, and far more forgiving when the gun does not arrive perfectly presented. An inch and a half at twenty five yards sits well inside anything that matters at defensive distance. The Holosun EPS Green 6 MOA is sized for a gun that gets presented under stress, and the precision it gives up is precision you would rarely be able to use.

Green At 540 Nanometres

The Holosun EPS Green 6 MOA emits at 540nm, almost exactly where human daylight vision peaks, so a green reticle reads brighter to your eye than a red one producing the same actual light. That buys contrast without buying current draw, and it shows up against brick, rust, timber, brown clothing and dirt, the colours that quietly swallow a red dot.

The honest other half, because nobody selling optics likes to say it: against grass, foliage and green painted steel, green is the colour that loses and red would serve you better. Buy the Holosun EPS Green 6 MOA for what you point the pistol at, not because green is the newer option.

Enclosed, Because A Carry Gun Collects Things

An open reflex sight, unlike the Holosun EPS Green 6 MOA, fires its emitter upward from an exposed shelf at a lens. It works until holster lint, sweat, sunscreen, gun oil or rain lands on that emitter, at which point the reticle dims or dies and you find out at the worst possible moment.

The Holosun EPS Green 6 MOA has no exposed emitter. The assembly is sealed inside the housing with glass at both ends, so there is nothing for debris to land on and nothing to wipe before you can trust the dot. That is the single most meaningful durability difference in the pistol optic market and the reason enclosed sights have taken over carry and duty use.

Ultra Low Deck Height And An Aspheric Lens

Deck height is how far the optical axis sits above the mounting surface, and it never appears in a comparison chart. A lower sight means less offset between your line of sight and the bore, which matters at contact distance, and it means standard height irons are far more likely to show in the bottom of the window rather than disappearing below it. The Holosun EPS Green 6 MOA is built deliberately low for both reasons, which on an enclosed sight takes real engineering.

The lens is aspheric rather than a simple section of a sphere, which keeps the image geometrically honest across the whole window rather than only in the middle. The dot stays round near the edges and the picture does not shift as your head moves, which is what separates a good enclosed sight from a cheap one.

The Plate Is In The Box

The Holosun EPS Green 6 MOA mounts directly to a K footprint slide, and Holosun includes an RMR to K adapter plate, so a full size slide cut for an RMR takes this sight too without a separate purchase.

One number to check first: adjustments move 1.5 MOA per click across 30 MOA of travel each way, coarser and shorter than the full size 407 and 507 optics. On a true slide cut that is ample. Through a stacked plate on a pistol that already points slightly off it is less headroom than you may expect, so if a previous optic fought you on that gun, mention it before you order.

Ordering

Manufacturer specifications are published at Holosun. We are a family owned FFL dealer in Collegeville, Pennsylvania, and we would rather confirm your slide cut with you first than have the sight come back. All six EPS variants are in our optics selection, each now named for what it actually is rather than all called EPS.
