View Full Version : 9mm upper question
04-17-2009, 10:33 PM
I'm buying a 9mm upper from a friend of a co-worker and I'm wondering if there is any differences in the lower parts kit that I should be aware of. Does it use the same buffer and spring as the 5.56 variant?

Get a ramped 9mm carrier or you can change to a 9mm hammer.
If I remember right, you get 9mm buffer and a spacer for retractable stocks and just a 9mm buffer for a full stock.

Depending on how the upper is configured (without seeing it I'm taking a leap and saying it is a complete upper assembly) I may go 'featureless' with a mmg, or a U15 stock.

Which kit? Olympic or Colt/RRA pattern upper? The Olympic uses sten mags and mil-spec trigger and buffer while the Colt/RRA might use a dedicated 9mm trigger and Uzi type mags.
