My SOG BAR15T, T for Tanto Bayonet should be here Saturday. They also make a BAR15C, C for Clip Point Bayonet in Black only. The BAR15T comes in Black, FDE, and OD Green. The black and FDE were on sale at GovX, and the Flat DARK Earth is a really light tan. I didn't like the looks of it so I ordered the black one. I'd rather have one with an OD handle instead. It was on sale too, but I didn't want to pay $5 more for it. The only review at GovX said, "
Heavy and Unbalanced It was foolish to put bayonet fittings on this wood-chopping, extreme wilderness camping knife. The blade is massively thick and the knife weighs far more than any other M16A1 bayonet I have in my collection. Hanging this on the end of a rifle would be insane. The knife is definitely blade heavy, so would seem to be best suited for chopping bamboo or using to split small wood into kindling." I went to Ontario Knife Company's website to compare the weight of an M7 Bayonet like I already have, and was (rarely) issued in the army. It weighs 1.15 pounds (18.4 ounces) and the BAR15T weighs 19.2 ounces (1.2 pounds). So it's only 0.05 pounds (0.8 ounces) heavier.
Suck it up Buttercup, it's only 4/5 of an ounce heavier. 
As my dad would say,
Far heavier, my @$$! https://www.sogknives.com/bar15t-tanto-bayonet/# https://www.sogknives.com/bar15c-clip-point-bayonet/ https://www.youtube.com/watch?v=pLVoDR5P06o
