Nice and solid, low profile, just needs a little loctite - JL Billet M-Lok Attachment Rail Section

Really like the finish quality on this rail section and appreciate the solid lockup it has with the MLok handguard. Does not come with any thread locker or such on the screws though, so you may want to drop a dab on the threads when you install. Properly torqued, they probably won't come lose. But a little extra, non-permanent security doesn't hurt.
