In this article, we will delve further into what exactly makes the AR-15 H2 buffer so unique compared to other types of buffers on the market. We'll explore its benefits and drawbacks as well as provide insight on how it affects an AR-15's performance overall. So if you're curious about upgrading your rifle's components or just want to learn more about firearms technology, read on!

AR-15 H2 Buffer: The Ultimate Guide

If you are a proud owner of an AR-15 rifle, then you know how important it is to keep your gun in top condition. One of the key components that contribute to the smooth functioning and longevity of your firearm is its buffer system. Among various types available, the H2 buffer has gained immense popularity among enthusiasts due to its unique design and benefits.

In this definitive guide, we will explore everything about the AR-15 H2 buffer – from what it is, how it works, its advantages over other buffers to tips on choosing one that best suits your shooting style.

What is an AR-15 H2 Buffer?

The buffer system in an AR 15 comprises a tube housing a spring-loaded weight called a “buffer”, which sits inside the stock assembly at the rear end of your rifle. When you fire around or cycle through several rounds quickly using semi-automatic mode or shoot while moving around (such as during hunting), these parts are subjected to intense vibration and recoil forces.

A buffer helps mitigate these forces by absorbing some portion of them while also decelerating bolt carrier group's movement just before reaching full extension thereby providing for smoother movement cycles with less felt recoil. An increased resistance from too heavy buffers can cause cycling issues with weaker loads as well as affect accuracy due prolonged contact time between bolt & barrel extension locking lugs slowing down lock-up time leading into worse performance especially if shooting longer ranges where every millisecond counts.

Hence different weights/types were designed catering for different shooters’ needs depending on their preferences – lighter ones aid faster cycling but may come at cost accuracy; heavier ones reduce felt recoil giving better control/accuracy but slower cycle speeds being more likely prone failures-to-feed issues with weak ammo loads until properly matched up.

An H2-style carbine length buffer weighs approximately 4 ounces (113 g) – 20% more than the standard "carbine" buffer – thus making it one of the heavy buffers available in AR-15 world. The H2 name arises from the military contractor, H-buffer, which designed it for use with a select-fire M4 model.

Advantages of using an AR-15 H2 Buffer

There are several benefits to using an AR 15 H2 buffer as compared to other types:

Reduced Felt Recoil

One of the most significant advantages is that an H2 buffer helps reduce felt recoil by absorbing more energy during firing and cycling action. The additional weight in this type allows for better control over your rifle while shooting or engaging targets. This feature comes handy especially when you need to take quick follow-up shots or maintain better accuracy while moving around.

Better Cycling Action

Another key benefit is that increased weight helps slow down bolt carrier group's movement just before reaching full extension thereby providing smoother operation cycles resulting into less wear & tear on receiver components and greater reliability when used with weaker ammo loads.

Improved Accuracy

An added advantage is that reduced recoil means reduced muzzle rise leading into faster sight acquisition time between shots allowing calmer position transitions increasing accuracy especially at longer ranges where seconds/milliseconds matter.

How To Choose An AR-15 Buffer?

Not all shooters have similar preferences nor do they all shoot alike – some prefer fast-target transitioning while others may choose more precision aiming/shooting so picking up right-weighted buffers matching their expectations can help improve overall gun handling experience.

To start choosing your ideal buffer, consider these factors:

  1. Rifle’s barrel length
  2. Shooting style—target shooting vs hunting
  3. Ammo load characteristics – lighter loads require lighter buffers.
  4. Your own personal comfort and preference

We recommend starting with heavier weights (such as H1/H2 models), then adjusting downwards if necessary depending on how comfortable you feel holding or maneuvering your firearm.

In conclusion, the AR-15 H2 buffer is a must-have component in your weapon system for better recoil control, improved cycling action and accuracy. Its unique design provides several benefits over other buffers, making it a popular choice among shooting enthusiasts.

Remember to choose one that suits your individual needs and preferences – lighter or heavier weights based on intended use-case scenarios with consideration given towards barrel length/ammunition compatibility for best results.


What is an AR-15 H2 buffer?

An AR-15 H2 buffer is a recoil-buffering mechanism used in the AR-15 rifle platform. The "H" stands for heavy, and the "2" refers to the weight of this particular type of buffer which weighs 4.6 ounces. Buffers are responsible for controlling recoil and ensuring that subsequent shots can be taken with accuracy.

AR-15 rifles have a direct impingement operating system that relies on gas coming out of the barrel to cycle back into the action to eject spent casings, load fresh rounds, and reset internal hammers or strikers; during this process, a considerable amount of energy is generated from firing each round which results in recoil being transferred back through every component involved in shooting an AR platform firearm.

The heavier weight of an H2 buffer can better control that energy transfer by slowing down how fast bolts move backwards after fired shots which reduces both felt recoil as well as muzzle rise caused by bullets exiting barrels while lowering stress levels within other parts such as springs involved with cycling actions.

How does it differ from other types of buffers?

The main difference between various types of buffers lies primarily within their weights since they all perform similar functions; that said some may also have specific design differences aimed at tailoring performance towards specific purposes.

For example:

  • Carbine Buffer: It has its weight divided equally between two parts weighing 3 oz., carbine-length buffers are lighter than most others and recommended for shorter barrels up until around 14 inches.
  • H Buffer: This set up uses only one solid piece weighing about 3.8 oz., so it's slightly heavier than carbine styles but still lighter than H2s.
  • H3 Buffer: The heaviest option available at around 5.6 oz., making them ideal when firing heavy subsonic loads or suppressed fire where extra mass helps reduce the speed of bolt cycling.
  • Adjustable Buffer: This type allows for customizing buffer weights by adding or removing tungsten, steel, or aluminum weights as needed to achieve an optimal balance between reducing recoil and ensuring reliable operation.

How does an AR-15 H2 buffer affect accuracy?

An AR-15 H2 buffers can improve shooting accuracy in several ways. By reducing felt recoil and muzzle rise with heavier-weight buffers such as the H2 variant, a shooter experiences less of a jolt from each shot making it easier to maintain proper sight alignment. This translates to faster follow-up shots without losing target acquisition which is critical in situations where every second counts.

Also, steady platform stability limits excess vibrations caused by bolting actions resulting in fewer variations that may impact bullet trajectories/accuracy. Finally having consistent speeds across bolt movements reduces wear-and-tear on parts involved allowing them to last longer without needing replacement which keeps your rifle running optimally at all times.

Is an AR-15 H2 buffer compatible with any rifle?

The answer here is no; compatibility will depend mainly on whether your firearm uses a carbine-style or rifle-length receiver extension tube (buffer-tube). Rifles equipped with carbine tubes require shorter buffers since there's less space available within these tubes compared to their counterpart versions designed for longer length tubes found on full-sized rifles.

AR-15s need different types based upon what kind of barrel you use too; lightweight barrels tend not only be sensitive but also generate more pronounced kickback so using lighter models makes sense while low-recoil match-grade barrels make heavy weight options like this even more suited due their design features aimed towards absorbing energy transfer better than lightweight versions hence providing greater stability during firing sequences

Always check manufacturers recommendations before you buy any parts since some aftermarket components may not work well together and cause issues rather than solve problems you are experiencing outside expected trouble-shooting scenarios associated normal operations.

How do I install an AR-15 H2 buffer?

Installing an AR-15 H2 buffer is not difficult, but it does require a bit of mechanical know-how. The first step is to remove the old buffer by taking off the stock and then sliding out the bolt carrier group (BCG). Once you've done this you can take out your current buffer that's situated towards rear of BCG after pulling off spring as well; once removed, place it somewhere safe.

Next up, replace old with new 'H2' model which should slide smoothly into place without any excessive resistance or effort required; be careful not jam anything since doing so would lead to misfiring issues during use.

Finally reassemble everything back in reverse order paying attention sequence upon putting buffers together before finally testing rifle to ensure there are no anomalies present during shooting sequences such as failures-to-feed or other common malfunctions associated with incorrect installations if they arise consult manufacturer instructions immediately for assistance because firearms mistakes can be costly at best and dangerous/life-threatening at worst if left unchecked.
