补充资料：91式35mm榴弹发射器
这种可肩射可枪挂的榴弹发射器被统称为35mm防暴榴弹发射器系统，顾名思义就是以发射防暴弹主的武器。这种榴弹发射器最先是作为驻港部队的qbz95式自动步枪枪挂式榴弹发射器而亮相的。尽管也可以发射杀伤弹，但目前没有资料指出已经配有杀伤弹种。整个武器系统中有4种型号：
型号 武器形式
qll91 肩射式防暴榴弹发射器
qlg91 挂装56-1式或56-2式冲锋枪
qlg91a 挂装81式或81-1式自动步枪
qlg91b 挂装qbz95式自动步枪
榴弹发射器的结构及高低压发射原理均类似于美国的m203，只是口径较小。发射器全长310mm，空重1.45kg，使用寿命大于2,000发，射程大约在300米，框架式瞄准具分划从75~350m，射击75m立靶时散布小于0.3×0.4m，实际射速约7~10发/分钟。
榴弹全长约115mm，全弹重约145g，初速为75m/s。目前已知的配用弹种包括：dfb91式爆震弹、dft91式痛球弹、dfr91染色弹、dfc91催泪弹、dfg91闪光弹。
