The only real way to know is to measure. There are some commercial tubes that are flat end.
If it is not a compliant model and has an adjustable stock, it
should be mil-spec dimensions. But again, with all the confusion regarding barrels between models, measuring is the only way to know for certain what is on your rifle.
