One of our students from our training courses paid me a visit this weekend. He thought it was time to add the advanced Slipstream treatment (ST-2) to his rifle. It turned out unbelievable. The trigger…all you felt was spring tension. There was no noticeable friction between the receiver and the trigger parts. The trigger break seemed almost eager. The sound of the buffer spring will never completely go away but was still smooth. The rifle turned out really well. I was happy with the results. Anyway, like the title eludes to, I have video proof of the improvements to the rifle. So here you go.
