I asked about the dust cover on the Milspec and I was told that new Milspec's no longer have the older, blocky dust cover. The Milspec guns have more features and are better "shooters" than the GI....if left stock. Once you send it to a 'smith, the better sights, blended magwell, lowered/flared ejection port etc are no longer an advantage since they will likely be replaced. If your going to shoot it for a while and then send it in for work, get the Milspec (if you like the slanted serrations, I do).
