Does the receiver say 715T? If it does then its a 715T, regardless of the stock you put on it. Doesn't the 715 and 702 use different magazines?
The 715T comes in the AR clam shell stock and a regular stock. The clam shells is banned the regular 715t isn't. The 702 and 715use the same magazines just 715t are in a plastic shell.
This is a factory 715t non Clam stock. These pictures are from the USA so 25 round magazines.
