i like the ring(s) as well as the big knob.
where did you get those?
Has it proved an aid to your follow up bang??
Out of curiosity, what is to be gained from a big knob?
I always understood that it was how you used it that mattered...
So you can get two hands round it when you're having ejection problems+1
why does one need such a big ugly knob on the side of the rifle?
