How to Disassemble AR 15: A Step by Step Guide

If you own an AR 15, it is essential to learn how to disassemble and reassemble the firearm. This knowledge will allow you to perform routine cleaning and maintenance on your rifle while also familiarizing yourself with the inner workings of your weapon.

Disassembling an AR 15 might seem intimidating at first, but it's a straightforward process that can be broken down into several easy-to-follow steps.

Safety First

Before we delve into the actual process of disassembling an AR 15, it's crucial to start with safety guidelines. Always ensure that you have unloaded your weapon before starting any work on it. Check multiple times if necessary, examining both the chamber and magazine well for ammunition.

Wear protective gear such as eye protection when working with firearms as they contain small parts that can become dangerous if mishandled or lost during cleaning processes.

Removing Upper Receiver Assembly

The first step in disassembling an AR-15 is removing its upper receiver assembly from the lower receiver assembly. Here are detailed steps:

  1. Remove magazines – As already stated above unload your rifle completely by removing all live rounds from magazine wells.
  2. Push rear takedown pin out – Use a punch tool or something similar and push this pin out towards right side of gun.
  3. Pull front pivot pin out – Similar like rear takedown pin use some tools which helps in pulling this one too
  4. Separate upper receiver assembly from lower receiver

Disassembly Of Upper Receiver Assembly

The next step after separating these two assemblies is taking apart different components of upper receivers such as barrel, bolt & carrier group etc., here’s what need be done:

  1. Support Barrel – Take support for barrel so they don’t fall off easily.
  2. Unscrew Charging Handle – Lift up charging handle upwards till point where take down lever comes near charging handle.
  3. Separate Bolt Carrier Group – Pull charging handle towards backside of upper receiver till it gets separated from bolt carrier group
  4. Remove Charging Handle – Hold onto charging handle, and push forward bolt carrier slide until you can lift the charging handle out of the upper receiver
  5. Remove The Bolt – Push the firing pin retaining pin out with a punch tool and remove it. After that hold onto bolt assembly while pushing forward on it to remove from inside.

Lower Receiver Disassembly

Finally, we come to disassembling lower receivers. Here are some steps to follow:

  1. Detach Buffer And Spring – Push down buffer detent with help of plier or something similar, then detach spring too.
  2. Take off pistol grip – Unscrew screw which holds pistol grip in place and pull off completely once fully unscrewed.
  3. Removing Trigger guard roll pin- Secure trigger guard's roll pin by using a bench vise or special punch for this very purpose & lightly tap using hammer until its removed completely


Disassembling an AR 15 might seem daunting at first, but if you follow these steps carefully and use safety guidelines throughout your work process; then there is little chance that anything would go wrong.

It's always good practice for gun owners who own AR-15s rifles to familiarize themselves as much as possible with their weapons' inner workings so they can perform routine maintenance without external assistance.

Moreover remember that everything has been previously mentioned should be done only after reading instruction manual provided along-with product very carefully.


What tools do I need to disassemble an AR-15?

Before you start with the process of taking apart your AR-15, you should have some essential tools. Some common tools include a bench vise, torque wrench, pliers, punches (brass and steel), hammer or mallet, cleaning kit and a vice block. Additionally, it's essential to ensure that all the screws are tightened correctly after reassembling.

The first step is to remove the magazine from your firearm and check that it's unloaded. The next step would be removing any attachments like scopes or sights before starting with disassembly.

Firstly loosen up the buffer tube by using pliers or an adjustable wrench. After unthreading this tube from its attachment point in front of where it inserts into your receiver (located towards one end), remove both detents at either end if necessary-the spring-loaded ones found inside each side channel on most models-and set them aside for later use as they help keep pressure against certain parts when firing rounds.

Next comes unscrewing two large screws located on each side near where they meet up with their respective handguards until these fasteners can slide out revealing more internal components which will require additional attention; however don't forget about those small pins known as trigger guards which also need extracting too!

How do I take apart my upper receiver?

To disassemble an upper receiver assembly of AR-15 rifle follow these steps:

  1. Place the upper receiver assembly upside down.
  2. Remove charging handle from bolt carrier group.
  3. Push forward retaining pin.
  4. Pivot open ejection port cover
  5. Grasp charging handle pull back slightly
  6. Push BCG forward out of upper
    7 ) Disengage bolt catch
    8 ) Separate BCG into three components

Make sure to clean all parts separately once taken apart so that every bit is cleaned properly without missing anything behind. Ensure that you don't lose any small parts while disassembling and keep them in a safe place.

How do I disassemble the lower receiver?

To take apart the lower receiver of AR-15 rifle, follow these steps:

  1. Remove magazine and ensure firearm is unloaded.
  2. Push out takedown pins found above trigger guard
  3. Separate upper & lower
  4. Remove Buffer Retainer Spring
  5. Remove Buffer Retainer
    6 ) Disassemble Trigger Group

Once taken apart, clean all parts separately so that every bit is cleaned properly without missing anything behind. Ensure that you don't lose any small parts while disassembling and keep them in a safe place.

How often should I clean my AR-15 firearm?

It's essential to maintain your firearms to avoid performance issues or malfunctions. It's recommended to perform regular cleaning after every use thoroughly. If not possible, at least once a month. However, this factor depends on how frequently you use your AR-gun; more frequent usage will require cleaning more regularly than occasional usage.

During cleaning make sure that all internal components are free from debris or buildup which may cause damage or malfunction over time when firing rounds.

Can I reassemble my assembled gun with some new components?

Yes! The beauty of an AR-15 rifle is its ability for customization according to one's preference as it has interchangeable components available in the market easily – such as triggers, barrels etc..

When reassembling guns with new components always ensure compatibility by checking specifications before purchasing items online/offline shops where they sell these types of materials specifically made for certain models like ours! Also be sure everything fits well together before tightening screws too far down onto each other so nothing ends up getting damaged during assembly process due lack awareness about compatibility between newly added customised componentry vs older pre-existing ones already present within original configuration based upon initial purchase order date/timeframe etc..
