Hi guys I have a stock M4, and I am looking to add a tactical light system - I'd rather not pay hundreds of dollars for a replacement rail system, as it's overkill for what I need. I can't imagine attaching anything else apart from the light (and perhaps a side saddle later). The main requirement I am looking for is that I can field strip the gun without tools. Any advice? .

Was watching the outdoor channel and saw Jerry M. using an X-rail on his Benelli. I love the toys! Adds like 14 more rounds capacity. Saw on the Xrail web site that they say the Xrail is not always reliable on the Benelli platform. So who has one?
