Thanks to Michael Skelton for the idea.
GT-5000 Grip Tape is very easy to use, inexpensive grip tape. You can apply it to many things like guns, knives, tools etc. I decided to make Magpul MOE Forend little more grippy.
When you buy GT-5000 Grip Tape you receive 6 stripes. I decided to make it like Michael did it on his shotgun:
You need to degrease Magpul MOE forend first and then measure and cut GT-5000 Grip Tape. Then process is very easy, you simply stick tape to the forend:
Now I have five GT-5000 Grip Tape strips and a half. I think I will apply it to stock too! It really made forend more grippy. Very nice and inexpensive way to improve your shotgun.
