Don't know if I want to save $150 and have to punch the A2 off the front and put a rail gas block on my first build. It pretty straight forward but is one more project I don't know if I want to mess with.
The most difficult part of replacing that A2 post is driving out the 1/16" roll pins. If you decide to do it, get a short punch. The longer ones (more than an inch long) have a tendency to bend before you drift the pin out. Been there, done that.
