Hello, I was wanting a clarification on the rule 21.2b for Carry Optics. Does it consider all of the milled out spaces (besides the hole by the barrel) on this one legal? Its the TTI combat master if the picture doesn't show up below. I saw a photo earlier of the high lady in CO at the nats using this piece with the only difference being the hole was not milled all the way through and it didn't have the magwell. It seems to me that all of the extra milling, specifically the front lower part being removed and the middle part where it says combat master at minimum, would fall under "Cuts that are designed to specifically or significantly lighten the slide, such as holes, are ruled as competitive advantage and prohibited." I just would like to have this clarified before I buy/build my new gun! Thanks!
