BUSHMASTER !!!!
I think the last lower I bought from them said : "Multi-Caliber"
It just makes them easier to sell, The market was full of lowers marked 6.8 Etc a while back, And they didn't seem to be moving as well.....So now they mark them "Mostly" either "CAL-MULTI" and "CAL .223-5.56mm"
They probably still mark them 6.8 if that's what you want/order, Or if the completed rifle came in that caliber.....Otherwise No Differences.
