Description
The Trinity Force .308 SBA (Silent Buffer Assembly) is a drop-in recoil system built to smooth out the AR-10 platform. Traditional carbine buffers ping and rattle inside the tube; the SBA replaces the standard buffer and spring with a self-contained captured system, so you get quieter cycling, less felt vibration, and cleaner harmonics on every shot.
Specs and features:
- Fits carbine-length AR-10 / .308 / large-frame semi-automatic buffer tubes
- Compatible with A2 rifle-length tubes when used with an A1/A2 spacer adapter (sold separately)
- All-in-one captured recoil system — buffer, spring, and guide combined
- High-strength aluminum body with heat-treated steel internals
- Reduced noise vs. a traditional buffer + spring stack
- Smoother recoil impulse and less felt bolt bounce
- Drop-in install — no gunsmithing, no permanent modification
Compatibility: intended for DPMS-pattern and other standard AR-10 / .308 lower receivers running a carbine-length receiver extension. Not for AR-15 / 5.56 platforms. Verify your rifle uses a standard AR-10 buffer tube ID before ordering; some large-frame clones use proprietary spec tubes.
