Does anyone here by chance have a digital scale and a 14.7" 5.56mm Light barrel w/perm. attached flash hider? If so could you give the exact weight of said barrel?

Also if anyone by chance knows the weight difference between the Mini and the Standard upper receivers (just the uppers themselves--excluding the pistons, barrels, op-rods, & other internals), could you kindly post this data?

Much appreciated!
