Shotgun as a primary?

[Jacob Wright]

Like people have said.. woodland probably not. But in urban environments you might fare better. 
 

I mind a time at Urban Assault where my brother had his gas shotgun as a primary and had great fun.. and success sweeping through some of the buildings and corridors!

Played for 2 years with a marui benelli before getting an AEG, this was back in 1999/2000.

Completely doable though in woodland and CQB

It's all to do with getting to know the gun, learning it and your limitations and playing accordingly.
