Recently got one of these in a swap and wondering what upgrades internally and externally would be a good idea. Looking for a full ris system on the front and want to replace the pistol grip and maybe the stock. Already got a 3x9x40 scope on there and the mag well is quite tight so wondering what to do with it. Want to make it as custom as possible
