Are youtalking about (after a final clean) for something to prevent rust in the bore? Then there are a-lot of good choices. Rem-Oil, WD-40, Birchwood Casey Gun Oil, MX Bore Conditioner, MX Gun Oil, and Im sure the BC Barricade is fine also, and the list goes on. If your talking about a Bore Conditioner, then it's up in the air on that one. Many manufactures claim to have what they call a Bore Conditioner, but you yourself will have to try them and see what works good . For now Im using the MX BC and as other's have'nt come to a conclusion as if this is the (BEST) or not, but from other's who have tested it, it seems to be doing a good job, only time and more test will tell. I for years used Bore Butter with good results, but other's hate it. So find out what you like and use it. Best of luck to you,,,,,,,,Ron
