Should be a 5-10 minute event but should you run into issues, try removing the stock. I had the old trigger out and the new one mounted up in about 3 minutes but the lower receiver WOULD NOT fit back on. I could take the safety selector off and it would slide right on. Could also see some rubbing marks on the upper "horseshoe" of the Timney. After scouring the interweb for about 10 mins I came across an article that said to try removing the 2 bolts holding the rear stock in place. Evidently there are very tight tolerances between the Timneys and SOME RPR stocks. I did this and voila...lower receiver popped right on. Tightened everything up and good to go!
Just figured I'd share the little tip in case any other RPR owners are dealing with the trigger issue.
