The stock AR-15/M-16 rifles are great, but there are some things that they can be better at; specifically their clips. The stock clip for any rifle will eventually lose its strength to push up the bullets into the chamber. You'll begin to notice a drop in the feed as time goes on or the clip not being able to keep up with your rate of fire and causing jams. Stability is another issue with most stock clips, they can fall apart on you as you use it more and more.
That's why companies like Magpul and Surefire are around to help replace those stock clips with ones that are proven to be better. They are easier to load and will provide years of support as you take your trusty rifle to the range. We offer both of these brands at a great price that anyone on a budget can afford, because we want you to have the best without overpaying for it.
