I didn't think that these were made. After fumbling with pistols and getting hot brass in the face/down the back of my neck, I'm pumped to hear that parts are made to make an AR a lefty gun, at least partially. Are there brands to avoid, how much more should I expect to pay? Issues with them in general? Are they even worth it? I can handle right handed guns, but if it's easier as a left handed person, and prevents me from getting dirty brass marks on my face, arms, and down my back, I'd prefer it. This is me shooting Market Garden's AR. You can see how close my face is to the ejection port.
