I may have acted a little prematurely, but I ordered a Fostech LITE Phantom AR-15 with the Echo II Binary Trigger already installed. I want to pull the trigger out of my Banshee 45 and swap it with the Echo II. I assume that this should be a straight forward process? The trigger separately was nearly $500. Got the complete rifle for $1000 plus shipping and transfer. seemed like a better deal. Can anyone predict any issues I might run into?
