Bolt action uppers for 6.5

[earlwb]

That is quite interesting. But it got me to thinking if one could simply use a side charging upper receiver with side handle BCG without the gas port connected. The bolt itself ought to stay locked until you pull the bolt carrier back to unlock it and extract the spent case. With the side charging handle out of the way, you don't have to move your head out of the way when pulling it back to extract the case and load another round. Do you think that the cases are too tight to manually extract them?
