AR-15 Triple Tungsten H3 Buffer | Heavy Carbine Buffer for Smoother Cycling & Reduced Felt Recoil | SKU/UPC 859819007225

Tame over-gassed carbines, smooth out recoil impulse, and protect your bolt carrier group with the AR-15 Triple Tungsten H3 Buffer (SKU/UPC 859819007225). Built with three tungsten weights, this H3-class heavy carbine buffer adds mass to slow bolt speed, improve extraction and ejection, and enhance last-round lock-back reliability—especially on suppressed or short-barrel setups. If you’re chasing softer shooting, cleaner ejection, and longer parts life, this H3 buffer is the proven timing upgrade your AR needs.

Why Choose a Triple Tungsten H3 Buffer

• Real H3 mass: Three tungsten weights deliver the heaviest common carbine buffer spec for serious bolt-speed control.

• Smoother recoil impulse: Extra mass reduces carrier slam, helping you stay on target for faster, more accurate follow-ups.

• Better reliability on gassy rifles: Aids extraction/ejection consistency and supports positive lock-back on empty with properly gassed systems.

• Suppressor synergy: Mitigates the added backpressure of suppressed fire to reduce wear and blowback at the shooter.

• Parts longevity: Lower cyclic rate can reduce battering of lugs, extension, pins, and gas rings over time.

• Drop-in upgrade: Installs like any carbine buffer—no gunsmithing required.

Ideal Setups

• Suppressed carbines needing slower bolt speed and smoother recoil

• SBRs / 10.3–12.5" uppers where gas is typically aggressive

• 16" carbines and mid-lengths that eject forward (1–2 o’clock) or feel snappy with hot ammo

• Duty/home-defense builds where reliability and parts life matter

Compatibility

• Platform: AR-15 / M4 pattern lowers

• Receiver Extension: Carbine-length tube (mil-spec diameter) with carbine action spring

• Gas Systems: Carbine, mid-length, and some rifle-gas 18" builds (tune with gas port/ammo)

• Not for: Rifle-length buffers/tubes, A5/intermediate tubes, or AR-10/.308-pattern rifles

Quick Install (Overview)

1. Clear & safe. Separate upper/lower.

2. Depress the buffer retainer and remove the current buffer & spring.

3. Insert carbine action spring and the H3 buffer (rubber bumper to the rear).

4. Reassemble and function check. Confirm lock-back on an empty magazine.

Tuning tip: Pair the H3 buffer with an adjustable gas block (or correct gas port) for a truly balanced, soft-shooting system—especially with a suppressor.

Troubleshooting & Tuning

• No lock-back: Check gas block alignment, ammo choice, and spring condition; consider stepping down to H2 if under-gassed.

• Brass at 1–2 o’clock: H3 is a strong choice; if still forward, evaluate gas reduction.

• Short-stroking: Verify gas integrity (block, key, tube), carrier movement, and use of correct carbine spring.

Specifications

Care & Maintenance

• Keep the receiver extension lightly lubricated—avoid heavy greases that trap grit.

• Inspect the buffer bumper and roll pin for peening; replace if damaged.

• Replace action springs periodically (3–5k rounds typical; sooner for suppressed/high-heat use).
