Hello, all! Alright, this has been something that I have been curious about for a while, but whenever I have looked I haven't really been able to find an answer... What exactly do you need to swap out a standard handguard for an RIS? I have this G&P: http://www.evike.com/product_info.php?products_id=32129 And I would like to make it look similar to this: http://www.ampedairsoft.com/product_p/pr15-145-tac.htm (Basically, add an RIS, and put flip-up sights on it) I've done some looking around, and have been unable to find exactly what is needed to swap an RIS for the standard handguard. I really like the look of the PR-15 Tactical Carbine, and have been planning on getting one so I won't have to worry about tech work while in college (just keeping m G&P to lend to friends if they want to try out airsoft), but since they are taking so long to get more VFC bodies in I am considering just dropping the FE in, provided I can make the external modifications. Thanks!
