^^^^^^They are a great alternative. It does require a little fitting. The amount you remove from the rear of the lugs will determine how much primary extraction you can get.
You'll have to determine if it's better than a new handle on your existing bolt. With the PT&G, you'll get a 1-piece bolt, no welded or soldered handle. You can get a different extractor, if that suits you, you'll have a choice of an .062 firing pin, and bolt knob. Truing and all of the other options are all added costs to your existing bolt, if you choose to do them, or have them done.
