Lbe Unlimited
An LBE Unlimited H2 carbine length recoil buffer is a weighted bolt carrier group (BCG) dampener designed to fine-tune the cycling speed of your AR-15. The correct buffer weight—H1, H2, or H3—depends on your barrel length, gas port size, gas system configuration, and the ammunition you're running. If you're experiencing overgassing, bolt bounce, or inconsistent lock-up, upgrading to a heavier buffer is one of the first tuning moves many builders make. This silver aluminum H2 buffer comes loaded and ready to drop into any carbine buffer tube.
The H2 sits in the middle of LBE's heavy buffer lineup, offering a practical balance for most carbine-length gas systems. Inside the body you'll find two tungsten weights and one steel weight—a combination that slows bolt carrier travel without being so heavy it causes short-stroking on lighter loads. Tungsten is denser than steel, so you get more mass in a compact package, which helps manage recoil impulse and extends component life by reducing impact stress on the buffer tube and receiver extension.
LBE Unlimited manufactures this buffer in the USA, and it's built for reliability on the range, in competition, or in the field. Installation is straightforward: it fits any standard carbine tube and requires no additional tools. If you're running a mid-length or rifle-length gas system, you'll want to verify your setup first—carbine buffers are sized for carbine tubes specifically.
| Product Name | LBE Unlimited ARBUFFH2 Carbine Length H2 Recoil Buffer |
| Brand | LBE Unlimited |
| Buffer Class | H2 (Heavy) |
| System Length | Carbine |
| Finish | Silver Aluminum |
| Internal Weights | 2 Tungsten, 1 Steel |
| Compatibility | Carbine Buffer Tubes |
| Manufacture | USA Made |
This LBE Unlimited H2 is designed for carbine-length buffer tubes only. It will not fit mid-length or rifle-length tubes. Verify your current setup before ordering.
An H2 buffer helps if your AR is overgassed, experiences excessive bolt bounce, or has reliability issues with lighter loads. The correct buffer weight depends on your barrel length, gas port size, gas system type, and ammunition. Experimenting with different weights is common during the tuning process.
Tungsten is significantly denser than steel, so it provides more weight in a smaller volume. The H2 uses two tungsten weights and one steel weight to achieve the desired mass and balance for carbine-length systems.
No. The LBE Unlimited H2 drops directly into your carbine buffer tube with no tools required. Simply remove your old buffer and insert the new one.
