Running with SDN6 and without, locks back on empty and very soft shooting as well. H buffer currently, have not felt need to go straight to H2 with it reliable right now. I also have a 11.5 bcm sbr as well. The MK18 is because I always wanted one and liked the simple look of it and had the opportunity to shoot an issued one(Not mines/ a SF Sergent's) when I was on active duty, I was hooked then.
That's an interesting option.....

I just did an 11.5 and my buddy with a pair of 6920's was looking into buying a sbr upper.

Notice any difference when comparing the two?
