Yep we have been selling
our rail panels for a while now. The grippy texture is no joke too, they are aggressive. They will eat softer gloves.
One thing of note is that they were designed to work with our rails, due to the attachment method. There are other rails out there that use different thickness for the MLOK sections, outside of the standard spec for aluminum rails, and those wont be compatible. If the lever is forced on rails like that it will break the panels at the latch. Many metal rails use the same MLOK spec but there are so many out there it's hard to get feedback on them all so we can only confirm fitment with Geissele rails. A good example of the different thickness would be the polymer handguards, they tend to be much thicker and usually wont work with these.
If anyone is using them with non G rails and can post your feedback with pics here it'd be appreciated!
