Has Zittara ever been produced by the OFB? Have not seen or heard of its use among the forces. Have only seen TAR-21 used by the Army special forces and X-95 used by CRPF. Both were directly purchased from IMI.
What I've quoted is from these two sources.

In late 2002, India signed an INR 880 million (about USD 17.7 million) deal with Israel Military Industries for 3,070 manufactured Tavor assault rifles to be issued to India's special forces personnel, where its ergonomics, reliability in heat and sand might give them an edge at close-quarters and employment from inside vehicles. By 2005, IMI had supplied 350–400 Tavors to India's northern Special Frontier Force (SFF). These were subsequently declared to be "operationally unsatisfactory". The required changes have since been made, and tests in Israel during 2006 went well, clearing the contracted consignment for delivery. The Tavor has now entered operational service – even as India gears up for a larger competition that could feature a 9 mm MTAR-21 version. Known as the Zittara, the rifle is manufactured in India by the Ordnance Factories Board for Indian service, the new Tavors have a modified single-piece stock and new sights, as well as Turkish-made MKEK T-40 40 mm under-barrel grenade launchers. 5,500 have been recently inducted and more rifles are being ordered. A consignment of over 500 TAR-21 Tavor assault rifles and another 30 Galil sniper rifles worth over INR 150 million (USD 3.3 million) and INR 20 million respectively was delivered to the MARCOS (Marine Commandos) in December 2010.
India's paramilitary and counter-insurgency Central Reserve Police Force CRPF ordered 12000 Micro Tavor (X-95) rifles (designation X-95), with the rifles entering service in early 2011. Following the use of the weapon by Indian forces fighting the insurgency in Kashmir, CRPF commanders have stated that the X-95 is a more effective assault rifle than the AKM, due to its small size, power, longer range and lighter weight.
