so I have an ASG M15 Armalite ARMS S.I.R Sports line and i wanna remove the sir system and add a standard m4 hand guard with a delta ring the problem is that i have no idea how to remove the sir system or how to install either things please help
the gun is also front wired from the hand guard so the hand guard i want to replace the old one with will make it easier for me
I also wanna remove the sir system because it's really flimsy at the bottom and feels too bulky for my style of play.
thanks.
