Hey guys been awhile since i've been on here. I was thinking about getting a set of quad-rail handguards for my AR-15A2 but have a few questions since I've never changed them out before. I wanted to get a set that I can change over myself on the coffee table in the living room without much trouble, do they exist or do they all require a little gunsmithing I also didnt want to spend a fortune on them. I work 2 extra jobs in addition to my primary job so I can have a little extra cash to play with, key word is little in that statement. I saw a set of them on cdnnsports.com that I can afford and since I've ordered from them before and was very pleased I figured they would be a great place to start. The handguards I was looking at are $69.99 for the rifle length and they are made by UTG. I know they aren't top of the line but neither is my rifle. Any thoughts?
