STANAG magazine
An export version called the QBU-97A is also produced and marketed for security forces of other foreign countries. This derivative utilizes 5.56×45mm NATO ammunition although, instead of STANAG magazine, a modified version of QBU-88 magazine is used to feed the rounds – and STANAG magazines will not work unless modified. The QBU-97A has recently been sighted under the designation NQU03, though it is unknown if the two differentiate in any way aside from name.
