Don't let it put you off at least not for a while. Though I'm glad a lot of the suppliers are stepping in to help product support, it should still fall on Magpul to make sure that they eliminate these little problems soon and before their products ship out. Plastic quality is excellent and its something they have going for them (at least for now). There are a ton of people waiting in the wings for the gas kit to come out and Magpul would be passing up a great opportunity not to have these things sorted by then.
