Is your existing gas block pinned, or is it clamped on or screwed in? If it is pinned, I suggest you take it to a gunsmith to change it, otherwise you might end up effing up your barrel, unless you are confident in your ability. The reason I bring this up is from past experience and the experience of others. The last time I removed one with pins, I had to use a hydraulic press to get the pins out. Took a while. I imagine if it wasn't for the press, I probably wouldn't even have fooled with it.
