I'm sort of confused ....is your point coming off the adapter or is the insert coming out if your arrow?
If your field points are coming off of your Ace glue-in-glue-on brass adaptors it is because of an issue with the bonding of the glue. Here is what works for me 100% of the time:Clean the inside of your field point socket with a Q-tip and denatured alcohol until the Q-tip comes out clean. Then use a wire bore brush (like you would use to clean a rifle barrel) chucked in an electric drill to give the inside of the socket a good brushing. Then clean it with denatured alcohol again.Melt some hot melt onto the adaptor, then heat the field point so it re-melts the glue as you install it onto the point. Let it cool and go shoot.The dirty inside of the field point socket will always fail unless you get it clean.
