Is there an easy way to limit a 20rd mag to 15rds? I need the length of a 20 but have to keep the capacity to 15.

Replacement follower with a long "tail" on the bottom that runs into the baseplate at 15rds?

only thing I can think of is the Square u shape metal in bottom of mag like the one they put in 20rnd mags to limit to 10rnds.

A rivet in the front of the mag to limit the follower travel.

Magpul makes 20-10s like this.

Put some wood in the bottom?

It fits inside of the mag springs and you can cut them to length

We made -2 limiters for 17 rd mags out of a cutting board.

If life was easy nobody would quit.

Got stuck a couple times with hicaps on hunting trips. I just cut a palm frond stem and and slid it into the mag to block it at the right length for 5 rounds.
