Yes, the only real difference between the 2 kits is the turret. And the casting level has improved greatly...I see I need to update the DPM scans...they are pretty old and the new castings look better than what is in pics on the webpage. The pictures for the BTR-T are much newer.
One Thing I will say...if you get the BTR-T, you will need a new 30mm barrel and muzzle break. That has always been a weak point of that particular kit.
Otherwise they are simple conversions to just drop down on the Tamiya kit. Pretty smooth.
