This is welcome news for those wanting to have an OPSCORE Fast Helmet with NVG mount and Side Rail but didn't bite due to its costs which is US$980 (international price). Now RSOV.com is the bearer of good news as it has something similar to it and just costs US$58.49. Available in green, tan, and black colours, the side rail is a good feature as you can have more attachments such as a tactical light or a helmet cam.

This is made by Loadout Master, and it is an IBH-style one and made modifications to it to make it look like the OPSCORE one.
