I have a LaRue Tactical SPR/M4 QD LT104 mount and a Hawke Sidewinder 30 Tactical SF 6.5-20x42 scope which has a very fine reticle. Prior to installing the barrel I lapped the upper with the lapping tool but I didn't bed the barrel extension into the receiver. The upper and lower are Aero Precision and I have a Daniel Defense Low Profile Gas Block Clamp-On. I also have a Midwest Industries Gen 2 SS-Series Free Float Modular Rail Handguard.
I polished/lapped the trigger and hammer very gently with a buffing wheel and Mothers but while shooting I felt it was still grinding very little - I might've not done it enough.
I used a torque wrench for the barrel nut and it just happened that at 30lb torque one of the cutouts lined up perfectly with the gas tube, so I didn't tighten it up more; I don't know if this has any effect at all.
Do I bed the barrel using blue locktide?
