Exta Etrigger and barrel

[indiana3433]

hey guys whats up, new to the forum.
Looking for some advice, I have a stock Xtra and i was to put and Eframe on it and a new barrel. Prolly J&J ceramic or Empire Whisper. Not sure. My questions are about the E Frame, is it simply unbolt the mech trigger and bolt of the E frame? any thing need changed while the frame is off? I am getting a Halo hopper to keep the feed speed up.
What you think??
