The AKM 45° Jack muzzle brake from Jack WBP (Wytwórnia Broni Jacek Popiński) can be used with WBP series weapons, as well as many other variants of AK47 and AKM rifles from different manufacturers. The WBP AKM 45° Jack muzzle brake is made of steel and black oxidized. There is a possibility that some weapons may require individual fitting.
The WBP AKM 45° Jack muzzle brake also acts as a muzzle protector for the barrel and functions efficiently as a compensator. As a compensator, it directs gases at the muzzle upwards and partially sideways, so that for right-handed shooters, it pushes the weapon against the left hand holding the fore-end.
WBP is a family company from Poland with an interesting and long-standing tradition. It prides itself on the high quality of its products and its own development and manufacturing. All weapons are made from the first screw to the last piece of wood stock in the WBP family business, so-called under one roof. They keep the entire process under their control. Approximately 90% of the production of one thousand weapons manufactured monthly at WBP is intended for export to the USA.
All internal components of the weapons at WBP must have precise manufacturing tolerance. One of the company's main strengths is its collaboration with members of special forces units, who test and provide feedback on the AK / AR systems for the company. This way, the most qualified individuals have their say, and WBP's production and development continue to climb the professional ladder and popularity.
