The POF BW-20 is an indigenous battle rifle of Pakistan Army, which has developed by Pakistan Ordnance Factories (POF); it was publicly unveiled in 2021 and subsequently showcased at the World Defense Show in Saudi Arabia in March & November 2022, including WDS in Riyadh and IDEAS in Karachi.

Regarding its development and production, the rifle is designed to meet the demands of the modern battlefield, leveraging the experience gained from producing the G3 rifle in Pakistan and utilizing the existing G3 manufacturing infrastructure.

According to POF, the BW-20 was developed to improve upon the G3A3 by reducing length, weight, and recoil, while also focusing on extending service life and ensuring compatibility with modern accessories.

The primary caliber of the Pakistan BW-20 is 7.62×51mm, and POF has introduced the rifle with various barrel-length configurations; specifically, 12-inch and 16-inch barrel options are listed on the official POF website. The rifle features a polymer magazine, an in-line buttstock, and support for modern accessories.

The BW-20 features a primary caliber of 7.62×51mm, and POF has introduced the rifle with various barrel lengths; specifically, options for 12-inch and 16-inch barrels are listed on the official POF website. The rifle incorporates a polymer magazine and an in-line buttstock, and supports the mounting of modern accessories. The polymer magazine is lighter than traditional metal magazines and offers superior resistance to rust and corrosion, while the in-line buttstock—aligned with the rifle's central axis—helps direct recoil straight to the rear. Furthermore, Its weight almost 4 kg with aluminum magazine and 3.9 kg with polymer magazine. And The BW20 rifle is a Semi-automatic and automatic rifle.

According to POF, the BW-20's design prioritizes reduced weight compared to the G3A3, which is why a polymer magazine has been used instead of a metal one. 

If we talk about its Operating mechanism , According to available defense industry sources regarding the BW-20's operating mechanism, it utilizes a roller-delayed blowback system—That technology closely linked to POF's experience in manufacturing the G3. 

It would be incorrect to view the BW-20 merely as a simple upgrade of the G3; it is a new indigenous design that retains some design commonality with the G3. Reports indicate that the objective behind the approximately 30% parts commonality was to leverage existing production infrastructure and manufacturing expertise.
