I have a MKII BTVSS. It has about 1500 rounds through it and has all of a sudden decided to what one would think is light strike. I use only Wolf Match ammo. I went 1200 rounds, zero issue, zero failure to fire and now all of a sudden it is 1 in every 5 rounds. I figured the bolt was dirty or something so I did a complete strip including removing the extractor, firing pin, and collar that holds it all in place. I degreased everyyyy thing and added a very light coat of M-Pro LPX. Put it back together and still... the same issue. What is going on here? The rounds that fire and those that dont have the same strike appearance. Could it just be a terrible lot of Wolf? I buy the 500rnd bricks.
