Product Overview
The LBE Unlimited H2 Recoil Buffer (ARBUFFH2) is a drop-in replacement component designed to work with standard carbine-length buffer tubes and buffer springs. The H2's aluminum construction is optimized to reduce reciprocating mass and dampen the violent impact commonly experienced with heavier steel buffers, producing a smoother bolt carrier group (BCG) return and a noticeable decrease in perceived recoil impulse. The silver anodized finish not only looks clean on modern ARs but also provides corrosion resistance and long-term durability.
This buffer is ideal for shooters who want better control during rapid strings of fire, reduced muzzle climb, and less wear on receiver extension components — all while maintaining compatibility with mil-spec carbine systems.
Key Features & Benefits
Carbine-Length Compatibility — Designed to fit standard mil-spec carbine buffer tubes and springs for straightforward, tool-free installation in most AR-15 carbine builds.
Lightweight Silver-Anodized Aluminum — Reduces reciprocating mass to smooth felt recoil and reduce the abruptness of buffer/buffer-tube impact.
Improved Recoil Management — Dampens the rearward impulse and helps reduce muzzle rise for faster, more accurate follow-up shots.
Enhanced Cycling Smoothness — Promotes consistent bolt carrier return and reliable ejection/feeding across a variety of loads.
Durable Finish — Silver anodize protects against corrosion and gives a clean, OEM-matching appearance.
Drop-In Upgrade — No gunsmithing required; installs quickly by removing the buffer retaining pin and swapping buffers.
Reduces Wear — Softer impact on the receiver extension and carrier can extend service life of internal parts.
Lightweight Design — Maintains rifle balance and handling characteristics, especially in carbine and SBR configurations.
Specifications
Brand: LBE Unlimited

Finish: Silver Anodized
Intended Use: Recoil mitigation, BCG smoothing, carbine/SBR/rifle AR-15 platforms
Installation (Quick Guide)
Safety first: Ensure the rifle is unloaded and the chamber is clear. Remove magazine and double-check that no live rounds are present.
Separate upper & lower (optional): Work with the upper separated for easier access if preferred.
Remove existing buffer: Depress the buffer retainer and carefully remove the buffer and spring from the buffer tube.
Install H2 buffer: Insert the H2 recoil buffer into the buffer tube followed by the buffer spring, ensuring proper orientation.
Function check: Reassemble rifle (if separated), perform a basic function check for proper cycling with dummy rounds or under safe, controlled test conditions.
Test-fire: Verify reliability and note changes in recoil impulse and cycling — start with a few rounds and confirm performance before extended use.
If you’re unfamiliar with AR maintenance or unsure about compatibility, have the installation verified by a qualified armorer or gunsmith.
Compatibility & Tuning Notes
The ARBUFFH2 is intended for mil-spec carbine receiver extensions and standard carbine buffer springs.
Using non-standard buffer weights, alternative gas systems, or exotic bolt carrier groups may require additional tuning (gas adjustment, different buffer springs, or alternate buffer weight) to achieve optimal reliability.
Not intended as a replacement for purpose-specific heavy buffers used in suppressed or high-pressure SBR setups without verifying function. If running a suppressed system, heavy loads, or non-standard gas systems, consult an armorer for recommended buffer and spring combinations.
Performance Tips
Pair the H2 with a mil-spec carbine spring for most general-purpose builds.
If you experience short-stroking or light ejection with certain ammunition, consider adjusting gas (gas block, adjustable gas block), or testing a slightly heavier buffer spring to restore full cycling.
For precision or competition use, check function with the specific loads you plan to run before committing to a final configuration.
Maintenance & Care
Inspect periodically: Check for visible wear, nicks, or deformation at the buffer face and body.
Clean as part of routine maintenance: Wipe down during normal BCG and buffer tube cleaning sessions. Anodize finish resists corrosion but regular maintenance lengthens service life.
Replace if damaged: If the buffer shows cracks, unusual deformation, or excessive wear, replace immediately to avoid damage to the receiver extension or BCG.
Why Builders Choose the LBE H2 Buffer
The LBE Unlimited H2 Recoil Buffer is a cost-effective, performance-oriented upgrade for carbine-length AR-15 platforms. Shooters report a perceptible reduction in felt recoil and improved follow-up shot control without the weight penalty of traditional steel buffers. Its anodized aluminum construction offers a modern aesthetic while providing functional benefits that improve the shooting experience for recreational, duty, and competition applications.
Safety & Legal Reminder
Always follow standard firearm safety rules: treat every firearm as if loaded, keep your finger off the trigger until ready to fire, point the muzzle in a safe direction, and verify the firearm is unloaded before performing maintenance. Ensure any modifications comply with federal, state, and local laws. If you are unsure about installing this part or its compatibility with your firearm, consult a licensed gunsmith or armorer.
