Thank you in advance for taking my question.
OK, have a complete RRA factory built "Civilian" Car A-4 Upper configured with:
16" Stainless Steel 1-8 Wilson Pre-Ban Barrel threaded w/Tactical Muzzle Brake (TMB) - Welded
Would like to no ban this configuration with your services along with:
Add M203 cut: as on M4 barrels $ 20.00
Bead Blast: Blast to a dull finish on SS barrels $ 13.00
Swap FSB: includes a sight base w/bayo lug $ 67.00
Disassemble - Reassemble: your complete upper $ 56.00
Concerning the heart of it all, the barrel, you are the expert, on the threaded TMB you can see a slight discoloration on the bottom where the folks at RRA put some heat to it, to be "Civilian" compliant.
Question: Can this be Barrel be salvaged with the same type of Muzzle Brake? and at what cost?
Best regards,
Rich
