Quickly identify which upper is chambered in which caliber with this rail cover for your Picatinny rail system.
If you’re planning a big range day, you’re likely bringing out every rifle in your collection. Make sure you and your friends know which is which with this rail cover marked “300 BLACKOUT.” The white text on the black background stands out and makes it easy to spot. With these rail covers, you can easily distinguish which caliber you’ll need for your rifle.
I picked this up so that if one of my buddies or my wife was shooting with me and didn't know what the caliber was they wouldn't feed it the wrong ammunition. Install was easy, it doesn't detract from the grip space and it looks good.
