Thunder Beast SR v2 Muzzle Brake - Secondary Retention NTB Mount

Thunder Beast SR v2 Muzzle Brake - Secondary Retention NTB Mount

Engineered for seamless integration with next-generation low-back-pressure suppressors and high-performance muzzle systems, the Thunder Beast Arms Corporation (TBAC) SR v2 Muzzle Brake (Non-Timed Brake / NTB) represents the evolved Secondary Retention mounting platform. Revised to be roughly half an inch shorter than the original SR v1 mount, the SR v2 footprint optimizes front-end weapon balance and internal volume clearance while maintaining TBAC's signature precision alignment, zero-shift mounting, and lockup integrity under heavy thermal cycling.

Offered in a Non-Timed Brake (NTB) configuration, this mount eliminates the need for timing shims or complex alignment procedures during installation. The SR v2 Muzzle Brake provides full backward compatibility, allowing legacy SR v1 suppressors—such as the Dominus, Magnus, and 338 Ultra—to lock down securely. Crucially, the shortened SR v2 profile is required for TBAC's newest low-back-pressure suppressors, including the SPIRO-SR, ensuring rock-solid secondary retention and repeatable point-of-impact performance shot after shot.

Features

SR v2 Shortened Mount Architecture:
Roughly 0.5 inches shorter than original SR v1 mounts, optimizing front-end weight distribution and providing clearance for modern low-back-pressure suppressor designs.

Non-Timed Brake (NTB) Installation:
Simplifies barrel installation by eliminating the need for timing shims, crush washers, or precise rotational alignment tuning.

Secondary Retention (SR) Lockup:
Heavy-duty secondary retention mechanism ensures positive locking, preventing carbon locking or backing off during rapid fire and extreme heat cycles.

Backward Compatible with SR v1 Suppressors:
Fully supports legacy TBAC SR v1 suppressor models, including the Dominus SR, Magnus SR, and 338 Ultra SR series.

Required Interface for SPIRO-SR:
Provides the mandatory mounting footprint for new-generation TBAC suppressors like the SPIRO-SR, which require the shorter internal clearance of the SR v2 brake.

Match-Grade Precision Alignment:
Maintains tight machining tolerances to deliver repeatable point-of-impact consistency and absolute mounting alignment across all host rifles.
