New guy here, just ordered my MP15 from Buds and I noticed that it is the CA compliant AR with the bullet button. I am sure this has been discussed before but what is the easiest/best way to take off the bullet button and install the normal mag release? I live in SC so I don't have to worry about it and I bought the CA compliant one because I was able to get it for really cheap. Any and all help is appreciated, thanks guys.
