Can anyone confirm the weights (in grams) of the MS lower and FA upper? I know a few FA uppers have shipped.

Lower (serial pre 000100): 290g w/ rear cross pin installed.
Lower (serial post 000100): 286g w/ rear cross pin installed.
SS upper (enlarged ejection port): 266g w/ shell deflector installed.
FA upper (standard ejection port): 258g w/ nothing installed.
*scale reads in 2g increments, so there is some margin of error. Weighed each item 5 times, went with the reading that appeared the majority of times.
