right now I have been using it on the bolt of my AR.
I have seen some firing pins stick with sewing machine oil.
On most of my other guns I have been using G96 without a problem. I am slowly changing over to Gunzilla and I will see how that works.
I was intreaged by the mobile 1 synthetic and like I said I have been using it on my AR , I gess I will see how it works this winter.
Thats why they call it hunting and not grocery shopping
