I want to turn the WE m14 GBB into a DMR, but I don't want the inconsistency of a gas rifle. I immediately thought of learning to drill and tap a magazine and using HPA, but I don't know if the stock nozzle can support FPS of 500+ (field regulations are 440FPS w/ .36). I see that Evike sells a nozzle for 500 FPS, and was wondering if that was necessary to buy in order for the gun to handle the FPS output of using an HPA.
With all of that said, I would also buy the RA-tech 6.01 barrel and hop-up
