Actually, the reason I wanted an M590 is because that is what I carried in the Corps back in the day. They had a bayonet lug on them then too so mine has one on them today. Same goes for my M870. Just as the 870's I carried when I first came into the USAF in 04 had the extended magazines with the bayonet lug magazine clamp, mine has one on too. Not planning to do a drive-by bayoneting but for historical correctness...and ******* off the libs.
