The Istanbul based ATA Arms brought out their 40x46mm BA40 standalone and UBGL grenade launcher to the show in Indo Defence 2018 this year. The launcher is the first such design from ATA Arms, which actually won a major contract this year for 8,000 launchers from the Turkish Land Forces. Another Turkish company MERTSAV completed a design that appears to have been for the launcher competition as well, known as the TAR-40.
The BA40 uses a breechloading tube that is attached to the receiver with an integrated trigger guard and ambidextrous safety selector. Once opened, the tube can actually be toggled to either the left or the right to be loaded. This allows grenades of varying length to be loaded into it (such as longer CS or riot control grenades). Athough the safety selector and the reloading direction are ambidextrous, the tube latch isn’t, being located on the left side of the launcher. The launcher can be used as a standalone platform when it is mounted to a standalone receiver with a double-sided Picatinny rail. Or it can be mounted directly to the 6 o’clock Picatinny rail of a rifle. In the case of Turkey, we should be seeing these BA40s in use with Turkish grenadiers on their MPT76 rifles.
