SureFire Ops Core Helmet Rail Mount for The HL1 Helmet Light

I bought this adapter clip to mount my Streamlight helmet light on the rail of my ballistic helmet.It is sure enough tight fitting to the rails so I coated the rails with a film of gun lube grease as far back as I thought I would push it back, using a cotton swab. I also coated the little shoe on the clip too. Slid right on so easy and it will come off as easy too.This is a quality product that is made tough and will last, a very good compliment to the light and should be included with every helmet flashlight of this type Streamlight sells.All said, I am very pleased with my purchase and recommend it to everyone who has this helmet flashlight.Just put a dab of grease on the upper and lower helmet rails as well as the clip’s shoe and it is an easy install.Pros: solidly made, works well.Cons: high price, should be included free with every helmet flashlight of this model.

It's such a tight fit that I had to build a wooden tool (just a simple rectangle the width of the rail with a notch cut out to accommodate the clip) and use a rubber hammer to get it onto the rail (or move it from spot to spot) without breaking it. Other than that it's fantastic. I just wish it came with the light rather than an extra purchase. And that it came in black, since my light is black and it looks a bit odd over a tan mount. Having said that, I'm glad I bought it.

wiggles a little in ops core rails but the light has stayed put in multiple mil sim games and regular use

This mount is awesome. My brother gave me this surefire light when he got out of the army but it only had the MICH mount. This mount is amazing. The light can pivot so its not just fixed in a certain angle. I really couldn't be happier with it. Well worth the money

Fits tight on the opscore rails. There is some play at the point where it pivots between the mount for the rails and the mount for the light. I looked at it closely but it doesn't seem to have a point of failure. I use it on my helmet for SWAT and it is constantly getting bumped/knocked around.

Size the old helmet mount is now basically obsolete. This mount is a great way to be able to use the HL1 with your high cut helmet rails.

The mount was very tight sliding into the grid on my helmet, may be my helmet. Light snapped right into place.

Disappointed. The mount attaches easily and securely (due to the lock). However, it's very loose on my Tacsnake helmet, letting it wiggle and rattle. I'd return it, but I haven't found a substitute.
