Is WD40 Good for firearms??, if so can you use it as a cleaning agent for your barrel?? I put some on my stock, receiver, and extieor barrel and bolt handle and it looked great but was that ok to do it?? Thanks
While it will displace water and give some rust protection, there are several strikes against it as a gun oil/solvent.
It is not intended for, nor is it particularly good as a cleaning solvent. It does have penetrating qualities, and
has been known to "kill" ammo that got sprayed with it in some carry guns. It tends to build up a gunky, viscous mess in hidden recesses of gunmechanisms where it cannot be wiped out often enough to prevent buildup.
There are much better products for cleaning and preserving firearms than WD-40. I recommend the use of stuff that's made for guns!
