The QLB-06 / QLZ-87B grenade launcher is a further evolution of Chinese QLZ-87 automatic grenade launcher. It was first unveiled to general public in 2006. The double designation (QLB-06 or QLZ-87B) stems from the fact that internal Chinese sources (press) call this weapon as QLB-06, while Poly Technologies Inc, an export corporation of PLA, calls it QLZ-87B in its advertising literature. Either way, this weapon is a further step in direction of a lightweight, one-man portable infantry support weapon which can be used on squad or platoon level. Because this weapon is even lighter than its predecessor, the QLZ-87, an automatic fire mode was abandoned, and the design was changed to better suit "rifle-type" shooting positions using integral bipod. Magazine capacity also was decreased. Nevertheless, it appears that basic action of the gun remained more or less the same. It is yet to be seen if this weapon will prove itself any good, but on paper it seems as a formidable squad- or platoon-support weapon against both enemy personnel or light armor.

The QLB-06 / QLZ-87B grenade launcher is gas operated weapon that uses direct gas impingement system. Barrel is locking by rotary bolt. Unlike its precursor, QLB-06 / QLZ-87B grenade launcher uses separate cocking handle on the right side of a newly designed aluminum alloy receiver. Cocking handle is of folding type. Barrel is fitted with prominent muzzle brake, and action employs an additional recoil buffer for moving parts in attempt to decrease the felt recoil. Gun is fitted with standard pistol grip with trigger and manual safety. Folding bipod is attached to the barrel. Adjustable open sights are installed on the top of the integral carrying handle, and a Picatinny rail is provided on the left side of receiver for installation of the telescope or night sight. 3X fixed magnification telescope sight appears to be a standard issue accessory for this weapon.

Ammunition range (DF 35mm) includes HE, HE-DP, HE-I and practice (marking) rounds, with maximum range of about 1750 meters. Muzzle velocity is about 190 m/s, complete round weights about 250 gram. For HE ammunition, lethal radius of fragments against infantry is listed as 10-11 meters. For HE-DP ammunition, armor penetration is listed as 80mm RHA (probably at 90^o).
