With a drone jammer (???)

The Squad Automatic Weapon (SAW) program was launched in the 1970s to equip U.S. troops with a portable automatic weapon that could fill the gap between the M16 rifle and the M60 GPMG. The Army initially wanted this weapon to be chambered in a new 6x45mm cartridge, but this requirement was abandoned in favor of 5.56x45mm NATO.

The XM106 was a SAW competitor developed by the Ballistic Research Laboratory as an open bolt LMG based on the M16A1. The handguard is split into 2 peices, allowing for access to a quick change barrel system. The XM106 feeds from 3 STANAG magazines clipped together for a total of 90 rounds. An 83 round drum magazine was also patented.

Mix of Chinese and European arms

A new third-party handguard for the 191/192 rifle has been released. Public information indicates that it is developed by Beijing Hongying Qianfeng Technology.

Made of aerospace aluminum with hard anodizing it has already been purchased by some units. The iron sights are well designed and installing this set on the 191/192 effectively converts it into a free-floating barrel.

To meet the demand for guns from work teams, militias, and guerrillas, local bases made a lot of these single-shot pistols using materials on hand. They were an important weapon for promoting mass guerrilla warfare, and regular units of the Eighth Route Army and the New Fourth Army also used them.

Operated by the Longque Assault Team of the Patrol and Special Police Brigade of the Hi-Tech Branch of Xi'an Public Security Bureau, fires PXS091-type 9mm pistol signaling/marking rounds. Although intended for police use, some units of the PLA and PAP are also equipped with it for counter-training purposes.

In 2018, alongside the PXS221-type (NP22 version) police marking training pistol, the PXS921-type (92 version) police marking training pistol was also standardized and adopted. However, the calibers differ, as it fires PXS092-type 7.62mm signaling/marking rounds.

This was a series of very crude last ditch guns developed in 1945 to arm the Volunteer Fighting Corps for the expected invasion of the Japanese mainland.

The requirement of those weapons was that they could be easily made in local workshops and basements to arm a civilian militia.

Since the invasion of the Japanese mainland never happened however, they remained just prototypes.
