Its considered to reduce wear, increase lubricity and make cleaning easier.
As for the cost, he charges $155 for an entire pistol, which is a lot more work in terms of disassembly and assembly.
If you have put a lot of rounds through your bolt carriers and they are not eating up the gas rings, then I have to agree with Klem. Mil spec is designed around a certain cartridge, powder and pressure. For us civilians, we use a plethora of different types of ammunition. If your BCG's have been working, "other than easier cleanup" I see little to gain for the money spent..
