I have a modded nf and currently it is the only gun in my arsenal except for a painted buzz bee tek 10. The nf has a crayola barrel and i was wondering how to reinforce the thing where the plunger goes in without destroying the gun. It is the first gun that i have ever modified, so i want to keep it intact. i know i am such a noob for asking this question, but, thats what forums are for...am i right? so thanks in advance.
