Masterpiece Arms DN5 Bolt Action Muzzle Brake – 30 Cal

Description

The Masterpiece Arms DN5 is a bolt-action muzzle brake built for high-pressure .30-caliber applications. This 30 Cal version is intended for use on calibers that generate increased gas pressure and volume, with examples noted including 308 Winchester and 7MM PRC. The brake is constructed from black nitrided high tensile strength steel and features a multi-port design to manage recoil and muzzle rise.

Key Specifications

• The thread pattern is 5/8-24.
• Caliber compatibility is listed as 30 Cal (308 Winchester and smaller).
• Material is specified as black nitrided high tensile strength steel.
• The design uses multiple blast ports that redirect propellant gases to counter recoil.
• The port geometry also directs gas upward to provide muzzle-down control for quicker follow-up shots.
• The manufacturer reports a tuned design achieving a 63% reduction in recoil using their test system.
• The brake is intended for PRS-style competition and other applications where extreme recoil reduction is required.
• The listed weight is 0.445 (value supplied by the manufacturer; units not specified).

Engineered for shooters who need strong recoil mitigation and consistent follow-up shot visibility, the DN5 provides a durable, competition-oriented solution for .30-cal bolt-action platforms. Its robust construction and targeted porting pattern make it suitable where controlled recoil and reduced muzzle rise improve shot-to-shot performance.
