I have a barrel I am going to send in for work soon. The barrel previously had a standard FSB installed. (read: It is drilled for pins.) The work I want done involves permanent flash hider installation; so, I need you guys to install my gas block.
Looking at a couple options for a GGG gas block. A) Install this one, as is, with clamp: 
B) Install the above and pin like a low-pro. (Is that possible? Excessive?) C) Use the version below and have drilled/installed with taper pins.

Installing the Clamp style will be much cheaper. It runs $90 (FSB Swap) to install the pinned Style. The pinned style is more secure, but the clamps seem to work well. I don't think there is a lot of advantage to pinning a clamp style on, since it is split, but suppose it might help a little. So, in my opinoin, either one will work just fine, just comes down to what you like (and want to pay for).
