Emerson Replacement Standard Strap Clips for Bump Helmet Rails
(Color: Foliage Green)

"Black ones.

My FMA helmet that I got from Novritsch did not come with these, so I wanted to complete the look of the ARC rails. These will fit, but will not lock in. You need to file it down so it will click and lock into place with a rasping file or even a long nail file. About 10 minutes of my time to file off 1mm of material. Otherwise, does the job.
