Best M-Lok Rail Grip inserts 2019

Same goes for the V2 on leaving exposed areas with the BCM covers. The V1 has additional slots and less exposed metal.

I like the Magpul type 2 covers. I’ve never had one come loose, in fact I have some that have been on a rail for years and it still takes considerable effort to remove them.

I don’t care for the BCM covers at all. Too narrow, too thin, still get toasty.

They are stupid expensive, but I love my Railscales G10 XOS panels. They are sweet on my Centurion C4 handguard, still maintains the small profile and has excellent heat protection.
