For the users that have a self indexing pcp huben k1 or L2 has anyone laser engraved numbers on the mag to keep track? My current way is a tiny piece of painters tape on the l2 mag on the left side to see it make a full rotation. I recently got the huben k1 and the tape doesn't work the same. I am wondering of I could have it laser etched and if it could be colored. Thanks for the input.
