What does a carbine buffer do?

A carbine buffer controls how your AR-15 cycles by working with the recoil spring and gas system. It helps manage recoil, reduce wear, and ensure reliable feeding and ejection.

How do I choose the right buffer weight for my AR-15?

Choose your buffer weight based on your rifle setup. Standard buffers work for most builds, while H, H2, and H3 buffers are better for over-gassed rifles, suppressed setups, or SBRs.

What’s the difference between H, H2, and H3 buffers?

The difference is in weight. H buffers are heavier than standard, H2 is heavier than H, and H3 is the heaviest. Heavier buffers slow down the bolt carrier group to reduce recoil and wear in aggressive gas systems.

Can I install a carbine buffer myself?

Yes, installing a carbine buffer is easy and typically takes just a few minutes. Most AR-15 lowers are already compatible with carbine buffer tubes and springs.

AR-15 Buffer System – Smooth, Controlled Cycling Starts Here

One of the most overlooked upgrades in an AR build is the buffer system — and it's often the one that makes the biggest difference. Whether you're dialing in for recoil control, smoother function, or gas system balance, choosing the right buffer weight can dramatically improve how your rifle performs.

At Mounts Plus, we offer a carefully selected range of AR buffers designed to help you get the most out of your setup. From standard configurations to heavier H1, H2, and H3 options, our lineup is tailored to match your rifle's needs.

🔧 Why the Right Buffer Matters

The buffer works in sync with your gas system and recoil spring to manage the cycling of your AR-15. A poorly matched setup can result in excessive recoil, erratic ejection, or increased wear on internal components.

Upgrading your recoil buffer helps:

Reduce felt recoil
Maintain smoother cycling
Improve reliability with varied ammo or suppressors
Extend the life of bolt carriers and receivers
Tune over-gassed rifles for optimal function

⚖️ Buffer Weights Explained

Different rifles call for different solutions. Here's a quick overview of the most common weights and where they shine:

Type	Approx. Weight	Best Use
Standard (Carbine)	~3.0 oz	Mid-length or balanced gas setups
H1	~3.8 oz	Slightly over-gassed or tuned rifles
H2	~4.6 oz	Suppressed rifles, hotter ammo
H3	~5.4 oz	Short-barreled or full-auto builds

Not sure what to pick? Our support team can help match your setup with the right weight.

🛠️ High-Quality Components from Trusted Brands

Each recoil buffer in our collection is made from high-grade materials and built to handle thousands of rounds without compromise. We feature brands like:

ATI Outdoors – Reliable standard and tuned buffer options
DPM Systems – Captured recoil units with advanced performance
Phase5 – Complete assemblies for pistol and compact builds
Deltac – Affordable, durable solutions for everyday shooters

These parts are compatible with most mil-spec AR-15 lowers and work with standard carbine-length buffer tubes.

🔄 Easy Installation – Immediate Improvement

Upgrading your recoil system is one of the fastest ways to improve control, especially if you’re shooting suppressed or with a shorter barrel. Most buffer replacements can be completed in minutes — no special tools required.

You'll notice:

Less muzzle jump
Quieter and softer shooting
Improved accuracy over longer sessions
