If memory serves me correctly the TAR-21 had a proprietary hopup chamber. Also If I recall the inner barrel in that gun has some major "wobble" issues. Shimming internal barrel, replacing the rubber on the hopup unit, and moving to a quality weight BB of no less than 0.28g will improve your performance.
