[ARCHIVED THREAD] - Receiver weight?

Posted: 8/21/2011 4:21:26 PM EDT

My search-fu is weak..

I am looking for the weights on the following upper receivers:

Standard M4 with port door cover and forward assist.

Both Vltor MUR receivers (the Vltor site lists then at under 8oz and 10oz but I am looking for the exact weight)

Les Baer M4 receiver w/o the forward assist.

Thanks
