iwi x95
The IWI X95 (formerly Micro-Tavor, MTAR or MTAR-21) is a compact bullpup assault rifle designed and produced by Israel Weapon Industries, predominantly available in 5.56×45mm NATO.
It can be distinguished from the TAR-21 series by the location of its charging handle which is closer to the pistol grip, straight lower buttstock shape (less jaggy outline) and a magazine release near the pistol grip. May have standard trigger guard or one that completely encloses the pistol grip. See Danbooru post #3059189.
This includes one of its major variants, the 9×19mm IWI X95 SMG (Danbooru post #6105143). Tag accordingly.
