Installing your new parts is quite simple, in fact, so easy we filmed ourselves doing it and uploaded it to youtube with no edits for pounding/cursing/throwing stuff/etc... If you have questions please don't hesitate to ask, we are the experts, but we understand we weren't born this way, so we won't treat you like you should have been either (that just means we are nice guys willing to help you out!). May your barrels be warm, and your groups be tight, but most of all let your AR look totally awesome.
