Hey,
New toy came in the mail this afternoon. I got it open and I find this on the rail system near the barrel nut. There are 4 blobs, 2 on top, 2 on the bottom.
Apologies if this is a dumb question, but any idea what this is? Is it normal? IS IT MAKING ME MORE TACTICOOL BY BEING THERE?
Gun is a VFC Mk12 Mod 1.
Looks silver in the pics, but colour matches the rail.
Any help appreciated!
