You can use the OCKS Carrier Key fasteners as well, which really help prevent fasteners from ever backing out.
Loc-Tite vs Permatex, Thread Sealant and Threadlocker Comparison
Some companies use Red Loc-tite 272 or Permatex Red sealant, both of which are high strength.
The Aviation-grade Form-A-Gasket is meant for sealing two pieces together like that.
A weakness of the AR15 carrier and carrier key interface is that the fasteners are located to the rear of the gas hole, so torque is applied and maintained behind the hole, not on both sides of it.
POF actually made a carrier and carrier key that dovetail together and only use one fastener to deal with this design feature of the standard Mil-Std configuration.
