"Lead in" or Flare dimensions of AR15 lowers?

There are significant differences between these flared magwells. Anyone got any measurements on the lead in of these or other flared lowers?


Noveske N4 or Gen 2

Thanks a ton Rob!

Looks like .14 to .3" flare on the Noveske.


My CMMG standard milspec lower is 1.1" x 2.7" on the outside just under the lip. My hand also shifted on the 2.7" photo which is why the reading is higher (2.8 instead of 2.7).

Inside dimensions 0.933" x 2.695"

Just to confirm Rob, is your Noveske lower Gen 2 / N4 ?

Thanks,

Jon

Looks like not all Noveske N4 / Gen 2 lowers are the same:

Noveske Gen 2 measured 1.44" external with my calipers, just over 1.2" internally just inside the lip.

Or people have different calipers... dunno
