Good look, good fit, good protection of sharp rail edges - Magpul XTM Enhanced Rail Panel Cover

Got this mainly for the aesthetics, but after I added it to the end of the rail closest to my hand placement, I realized that this a tool I needed and didn’t even know it. The rail on my receiver end just after the start of the handguard and has a small section of rail at the end of hand guard for an iron sight. I didn’t realize the level of comfort and peace of mind I would gain from adding this little piece to the end of my rail where my hand, or anything I don’t want damaged, can make contact with the corners of the rail.
