I was searing for a decent price quad rail hand guard since I am on a low budget right now and I came across one on Amazon sold by American Tactical. It is a mil spec 1913 picatinny rail system with T6 aircraft aluminum body. 4 rail bolts help hold in place and it also came with 4 rubber ladder covers. It took about 3-4 minutes to install since I don't have a delta ring tool and its on there pretty solid. No wiggling or movement from it and I paid about $50 with shipping and made in the USA. So far I like it and it seems to be able to hold some items that I will obtain in the future. I will have to see how it feels and handles once I take the rifle out to shoot. Here are some pictures and let me know what you think.

Looks like a good value for $50. Nice upgrade.
