So I just bought an A-5 that has a R/T on it (still waiting for it to come in the mail). I've used them before but never owned one so I had a few questions. Is it possible to swap out the R/T grip for a stock grip or an E-grip? My buddy has a R/T on his A-5 and when we took off the grip it looked like it was questionable if the gun would operate with a different one. Also how good does the R/T work with the flatline barrel? Thanks for the help guys!
