Still FTEs. I am going to polish the FCG and shoot it some more to break it in, then if it still FTEs, I am going to apply the S12 solution of drilling out the holes and/or adding another. The only problem I see is that the Gas block is not the same as the S12. the two pins are on the bottom of the block, on the same side of the bbl. Not on either side as in the pics of the S12 fix. Can someone verify these two pins will release the b;lock?
