Roller-Delayed Blowback System
The PTR 51P-BR utilizes the classic roller-delayed blowback operating system, the same proven design found in the HK G3 and HK91 rifles. This system provides exceptional reliability, smooth operation, and the ability to handle a wide range of .308 Winchester ammunition. The roller-delayed mechanism helps reduce felt recoil and improves overall shootability, even in this compact 8.5-inch barrel configuration.
The PTR 51P-BR delivers powerful .308 Winchester performance in a compact PDWR format with an SB Tactical brace and 8.5-inch barrel.
Compact 8.5-Inch Barrel
This model is equipped with a short 8.5-inch barrel, significantly reducing the overall length of the firearm while maintaining the terminal performance of the .308 Winchester cartridge. The compact barrel makes the 51P-BR highly maneuverable in tight spaces, vehicles, or during dynamic movement. Despite the short barrel length, the roller-delayed system helps maintain reliable function and manageable recoil.
SB Tactical Brace
The PTR 51P-BR comes standard with an SB Tactical brace, providing shooters with improved stability and control. The brace allows for shouldering while offering additional support during firing. This feature enhances accuracy and makes the firearm more comfortable to shoot, especially during rapid fire or when using the powerful .308 Winchester cartridge in a compact platform.
