The phone presents a slightly different view from what it looks like to the naked eye. 
For example, when i put my cheek to the stock, i don't really see the scope rear frame.  Just the view. 
It also exacerbates the interference of the stock and the can. 
For those mentioning lugging a can - I'm in agreement on being mindful of weight.  But taking the suppressor is worth it to me.  The cut removed from the barrel makes it about 6-8 oz lighter, the can weighs 15 oz.  Delta of 7 oz. increase. 
The overall length of the rifle with can installed is just under 47" 
I would challenge anyone to detect the difference if blindfolded compared to a stock config.
