The Tavor TS12 Knurled Charging handle projects out 1/4" farther than the OEM handle and has a 1/2" diameter knurled drum for good purchase, and we have found this to be the perfect size to give a good grip without racking knuckles on the receiver yet the handle does not project out too far from the side of the gun. Just like the OEM handle the Knurled Charging Handle will work on both the left and right side of the gun and is a drop in replacement. FeaturesProjects out 1/4" farther than the OEM handle and has a 1/2" diameter knurled drumWill work on both the left and right side of the gun and is a drop in replacement NOTE: Early production handles are solid with two sets of notches on the "shaft" that goes in the gun. Current production handles have a hollow handle portion and a single set of notches on the shaft that should face rearward during installation. The design changes do not affect performance of the handle and were for manufacturing purposes.
