These are thermal fit receivers. You will need to heat the receiver in order to install your barrel
Heat the receiver in an oven set at 250*. Install the barrel and let it cool to room temperature before you install the barrel nut
GENTLY heat the front of the receiver with a propane torch. Do not overheat the receiver. You need only to heat it slightly to install the barrel. Install the barrel quickly and let cool to room temperature before you install the barrel nut.
