I been using moly to lube my guns for many years, all my guns. I been using the moly TS-70 paste but there's also a 525 moly grease too. The 525 was recommended from the TS moly people for guns also.. I just purchased the 525 and some moly grease to try on my tractors too. I been also using the moly grease from TSC (tractor supply company) too.
I'm hooked on moly in the guns too.
I burnished the ts 70 moly paste into one of my new saiga's (AK/AKM) in 308win. The three of us hammered it at the range putting it thru its paces just to see how good it operates and how accurate it is. When we got home i cleaned all the guns but i forgot to reapply the moly in the saiga. When i clean the receiver i just wipe out the moly and just apply more new moly. I only wash the barrel with solvent only then oil it up. Well the next trip to the range we hammered it again and at the end of the shoot i remembered i forgot to reapply the moly on the frame rails and bolt carrier and bolt. When i took off the receiver cover i was expecting the worst. Nothing showed any kind of wear at all. The orginal finish is still on the frame rails too. The moly that was burnished into the pores of the metal saved my butt. Also in seeing this it tells me in a really very cold climate (artic cold)i can wipe out the moly and it will still be in the pores of the metal protecting your/our guns against wear when hunting. When i say that moly eliminates all wear you can bet it does and my mistake proves it. There is no metal to metal contact when moly is used. It also reduces friction too.
Now my new Auto Ordnace 1911a1 WW2 copy 45acp that has over 500rds thru it now the frame rails/gun has been lubed with moly since it was right out of the box new. My point is the front of the frame rails/slide shows no side to side wear yet. I believe that moly has eliminated his wear from happening in the front frame rail/slide area. I'm also using the full length guide rod kit with the 18# recoil spring too. So some of the extra side to side forces with heavier recoil springs is eliminated also. But either way i stil have the orginal fit on the frame to slide rails after 500+rds thru it. Every used 1911 in this area is as loose as a goose while the rear rails are still tighter. (front area) If you need directions on how i apply moly for the first time ask me. Moly my guns never leave home without it.
