This is for a 10.5 inch 5.56mm barrel that is overgassed.  Other solutions to the issue would be appreciated.

BRT EZ Tune gas tube or a Rubber City adjustable gas key would be the easiest and least expensive other options.

BRT .071 gas tube is equivalent to a .069 gas port which is perfect for a 10.5” barrel.

Outside of modify a standard FSB this is the only option I'm aware of.

The BRT gas tube is a great option.

If it is a standard large gas port 10.5" barrel, an H3 buffer usually works well them.

The small gas port barrels that length often like an H2 buffer.

If heavier than H3 is required (doubtful), a PWS steel H4 buffer could be tried, but it is very heavy and might be too heavy.

With large gas port 10.5" barrels, I go straight with an H3 buffer.

I bought one of these and it is pretty solid. Tightened it with a torque driver to 50 psi and it will not budge.

I wondered when someone would post a windage adjustable FSB that OP didn't ask for. It would be nice to have a clamp-on available in Armalite's stead, but aluminum? Fail.
