This is the only area of AR-dom where I regret buying a lefty Stag. As far as I know, the only parts that won't match up are the bolt and bolt carrier. Does anyone else know of other nonstandard parts on a lefty Stag that I would need to get directly from them? I assume that the firing pin, retaining pin, and the bolt cam pin are the same, but I'm not sure, it's my first AR so I don't have another one to compare it to.
