But now that everyone is coming out with .308 versions, in the M4 platform, not sure the room clearing/close quarters can be used anymore. The .308 has a lot more a$$ behind it, but the last time I checked, going door to door was a mans job. But the way they’re pushing kids thru basic these days, not sure how many qualify as men, as the PC monster has infiltrated.
However, my Noveske Leonidas is wonderful. 12” barrel in .308. Its a masterpiece.
I don’t dispute the advantages the 7.62 has. In fact, you can get a .458 SOCOM to work with your 5.56 lower and magazines for some real CQ punch. The initial debate, however, was over the soundness or the AR family design an the effectiveness of the 5.56 round. My point was, at ranges within 250 m, I believe the 5.56 performs well enough to be regarded as something other than a hot 22LR due to its yawing, spalling, and fragmenting characteristics.
