Understanding AR-15 Buffers and Their Role
What is an AR-15 buffer and what does it do?
Before we delve into the specifics of the Spikes Tactical T2 Buffer, it’s crucial to understand the fundamental role that an AR-15 buffer plays within your firearm. The buffer, along with its corresponding spring, resides within the receiver extension, also known as the buffer tube. Its primary job is to manage the rearward movement of the bolt carrier group (BCG) after a round is fired. This recoil energy is then used to cycle the action, extracting the spent casing, chambering a fresh round, and preparing the rifle for the next shot. Without a properly functioning buffer, your AR-15 will likely experience a range of problems, hindering its performance and potentially damaging internal components.
The buffer also serves a secondary, yet critical, purpose: to dampen the impact of the BCG as it travels rearward and forward. This cushioning action reduces the amount of stress on various parts, including the bolt carrier, receiver, and even the buffer itself, contributing to the long-term durability of your rifle.
There is more to selecting the proper buffer than you might think. The weight of the buffer is a critical factor, as is the composition of the weight and the spring used. The right combination can make a big difference in reliability and how the rifle feels while shooting.
Different Types of AR-15 Buffers
Different types of AR-15 buffers exist, each designed with varying weights and internal configurations. Common varieties include the standard carbine buffer, the H buffer (heavier), the H2 buffer (even heavier), and specialized options like the T2. The appropriate buffer for your AR-15 depends on several factors, including the barrel length, gas system configuration, and the type of ammunition you are using.
Common AR-15 Problems and How the Buffer Can Affect Them
A poorly chosen or inadequate buffer can lead to a host of issues that will detract from the enjoyment and usefulness of your rifle. These issues can include:
- **Failure to Cycle Properly:** The buffer and spring system may not be correctly matched to the rifle’s gas system, causing the bolt carrier group to fail to cycle completely, preventing a new round from chambering. This can happen in either direction, either failing to extract the spent round or failing to chamber the new round.
- **Bolt Bounce:** In some cases, the bolt carrier group may bounce off the buffer after cycling rearward, leading to malfunctions like light primer strikes.
- **Premature Wear:** The impact of the bolt carrier group on the receiver extension and buffer can cause accelerated wear and tear on the bolt, carrier, and even the receiver itself, shortening the lifespan of these crucial components.
- **Increased Felt Recoil:** A buffer that’s too light can cause the rifle to experience more recoil, making it less comfortable and more difficult to shoot accurately.
Deep Dive into the Spikes Tactical T2 Buffer
What is the T2 Buffer?
The Spikes Tactical T2 Buffer represents a significant upgrade over the standard carbine buffer. Its design and construction are specifically tailored to address common AR-15 problems while enhancing the overall shooting experience. But what makes this buffer so special?
The T2 buffer features a carefully engineered internal arrangement. It typically uses a combination of tungsten weights (usually two) to provide the ideal weight and inertia to manage the bolt carrier group’s movement.
Specific Weight and Characteristics of the T2
The specific weight is one of the key features that set this buffer apart. The T2 is usually heavier than a standard carbine buffer but lighter than an H2 buffer. This intermediate weight allows for optimal performance in a variety of setups and reduces the chance of issues like short stroking or over-gassing.

Installation and Compatibility
Is the T2 Buffer right for you?
Getting the Spikes Tactical T2 Buffer set up on your AR-15 is relatively straightforward, but it’s important to follow proper installation procedures.
Before you begin, it’s always a good idea to verify the correct buffer weight for your AR-15 setup. Barrel length, gas system type, and the ammunition you intend to use are key variables to consider. The T2 usually works best for mid-length and carbine-length gas systems. However, some experimentation may be required, particularly if you are dealing with unusual components or are using a suppressor. If you’re not sure, consult with a gunsmith or experienced AR-15 enthusiast.
Step-by-Step Installation Guide
Here’s a general step-by-step guide to the installation process:
- **Remove the Existing Buffer:** Begin by disassembling your AR-15’s lower receiver. This involves removing the takedown pins and separating the upper and lower receivers. Next, remove the buffer tube (receiver extension) from the lower receiver, being careful to retain the buffer detent and spring. Remove the existing buffer and spring from the buffer tube.
- **Insert the New Spring:** Insert a new AR-15 buffer spring into the buffer tube. A quality spring can further enhance performance.
- **Insert the T2 Buffer:** Slide the Spikes Tactical T2 Buffer into the buffer tube.
- **Reassemble:** Reinstall the buffer tube onto the lower receiver. Ensure that the buffer detent properly engages the groove on the buffer.
Remember to always follow safe gun handling practices. If you’re not comfortable performing this procedure yourself, consult with a qualified gunsmith.
Compatibility Considerations
The T2 buffer is designed to be compatible with standard mil-spec AR-15 buffer tubes. It is important to have a good quality receiver extension.
Troubleshooting
Common Issues and Solutions
Even with a high-quality component like the Spikes Tactical T2 Buffer, occasional issues may arise. Here’s a look at common problems and how to troubleshoot them:
- **Short Stroking:** If your AR-15 fails to cycle completely (i.e., the bolt carrier group does not fully travel to the rear), the buffer might be too heavy for your gas system. This is not as common with the T2. Consider using a lighter spring.
- **Overgassing:** If you experience excessive recoil, ejection patterns are erratic, or you have a fast cyclic rate, the gas system might be overgassed. The T2 may help mitigate some of these issues, but a gas block adjustment may be needed.
- **Failure to Feed or Extract:** These malfunctions are often caused by problems within the magazine or failures of other components. However, cycling issues can also be exacerbated by an improper buffer and spring combination. Ensure that your rifle is clean, properly lubricated, and that your magazines are in good working order.
- **Light Primer Strikes:** If the firing pin fails to ignite the primer, it could be an indication that the bolt carrier group does not have enough inertia to strike the primer with enough force. An incorrect buffer or spring combination could be a contributing factor. Make sure all components of the fire control group are in good order.
If you are uncertain about the source of a malfunction, seek guidance from a qualified gunsmith.
