Well, it's just that I rather like the idea of buying the 'lite' version of a rifle, and only adding the bits as and when you need them.
eg; shockers are - what? £500 new?
So - £35 for the decent feedneck and replace with a low-end stock one, get rid of the nice AA barrel = £50, the Oops could prob generate £30, the trigger say £20
Suddenly you have a new £350 shocker...
Just a thought - I think it's not a disadvantage but marketing brilliance - particularly at that end of the market
