Gas System
The AR15 has two gas systems:
- Direct Impingement (DI)
- Piston Driven
If this is your first time buying an reliable AR15, please go for a direct impingement gas system 7" or more. Generally these are standard 16" long barrel rifles with the most balanced components for reliable use.
The Stoner DI design is the most common, which involves redirecting the hot gas leaving the barrel back into the gun to recycle the bolt carrier group via the gas tube.
While the direct impingement system can be very reliable, there is no doubt that a lot of fouling can build up on the bolt carrier group.
There are 4 major DI gas system lengths:
- Pistol 4"
- Carbine 7"
- Mid Length 9"
- Rifle Length 12"
The Piston Driven design uses the propellant gas to operate a rod that acts as an intermediary to exert force on the bolt carrier group to cycle the weapon.
All excess gas is bled out of the gun well forward of the receiver. This helps keep the guns extremely clean. Ultimately it's just like how an AK47 operates.
Caliber
The AR15 platform has evolved over time. Now the AR15 can be chambered in these most popular centerfire cartridges besides 223/5.56:
- 6.5 Grendel
- 300 BLK
- 22 Nosler
- 450 Bushmaster
- 458 SOCOM
- 350 Legend (See 350 Legend upper)
- 50 Beowulf
- and more...
Durability
Most AR15s are durable, but there are couple key areas a buyer should pay attention to for more durability.
- Features Staked Castle Nut Ring ?
- Features Anti Rotational Handguard Locking Mechanism ? Prevents the handguard from getting loose
- Features Forward Assist ? Helps seat the bolt & clear malfunction
- Features Anti Rotational Trigger Pins? Prevents the trigger pins from popping out of the receiver
Bolt Carrier Group
The bolt carrier group (BCG) is one of the core components of the rifle that holds the hammer, striker pin, extractor, gas key & the rotating bolt.
Most ARs you find on the market today will ship with full auto M16 bolt carrier group.
There are differences between an AR-15 and M-16 bolt carrier group. The fully automatic M-16’s bolt carrier group has more material on the back, for starters, allowing compatibility with a fully automatic sear.
Must be tought built - Because of the BCG experiences powerful forces, it is important that no weaknesses exist in the metal. In order to ensure that, the makers of your BCG put their products through a battery of tests.
Look for MPI rated BCG - These tests include magnetic particle inspection and high-pressure testing. Magnetic particle inspection ensures that there are no breaks or cracks in the metal the bolt carrier is made of.
Manganese Phosphate (Most Common) - Its benefits are that it’s economical, durable, and corrosion-resistant but, due to its highly porous nature, it is also difficult to clean.
Chrome - Chrome is both harder and more porous, both of which make it easier to clean. Unfortunately, it is expensive and brittle.
Nitride - Nitride is a chemical treatment that results in a hardened black surface. It is durable and highly corrosion resistant. However, if it is not done properly, it can have a negative effect on the sensitive part of the bolt carrier group.
Electroless Nickel (Smoothest action) Electroless nickel results in a thin surface layer that is harder than the underlying metal. It has excellent lubrication properties. While easy to clean and less reliant on lubrication, however, the coating can wear off over time.
Upper Receivers [Core Components]
The upper receiver hosts the barrel assembly, optic, sights, charging handle and the bolt carrier group.
The A2 style upper receiver is the most common, meanwhile custom / cool looking billet upper receivers are available too if you want something unique.
Who makes them ? The upper receiver forgings are all essentially the same, they simply come from different forging machine shops.
So quality and tolerance do vary. You can identify which forging shop your receiver is made from by looking at the stamp.
The most common two are:
- ‘Keyhole’ (Cerro Forge)
- ‘Square’ (Brass Aluminum Forging Enterprises)
but you will see more if you keep looking.
What's cool is that you can put on other upper receivers for different applications and looks later down the road. Check out more complete upper receivers here.
Lower Receivers [Core Components]
The lower receivers host the trigger group, pistol grip, spring system, stock, magwell, mag release and upper receiver retainer pins.
The main receiver is considered a firearm, which requires FFL when purchasing. People can buy a complete lower or build it piece by peice.
There are tons of accessories available on the market for it as well.
Accessories [Attachments, Grips & Stocks]
This part is self explanatory, and they improve the handling and ergonomics of the rifle, but not the basic operation of the rifle. Please check out our links below:
Handguard
The handguard is what fundamentally makes the AR15 more tactical looking & configurable, and one of it's major usage is to provide additional mounting space for accessories.
Currently the most popular handguard mounting systems are:
- Picatinny [Expensive for CNC machining]
- M LOK [Easier to Machine]
- KeyMod - The KeyMod handguard was developed as a collaboration between VLTOR Weapon Systems and Noveske Rifleworks.
Instead of having a hand guard with a picatinny rail attached, the KeyMod & MLOK were designed so that accessories could be mounted directly onto the rail. This also allows for picatinny rails to be mounted onto the handguard wherever needed.
A sturdy and tight tolerance CNC machined handguard is important to secure any laser devices for zero retention.
A good handguard system consists of the following:
- Rock solid barrel nut
- Anti rotational handguard tab that hold on to the upper receiver
- Handguard should be bolted onto the barrel nut (No friction clamp)
- Aligns with flat top receiver
- Enough mounting locations for accessories
Barrel [Twist Rate, Length & Lining]
There are tons of AR15 barrel options on the market today. Different material, lengths, profile and twist rate can affect the ballistic performance.
Overall, Cold Hammer Forged barrels are the most durable with the longest service life on the market.
Every barrel has the rifling groove inside, and the twist rate is represented as follows:
1:8 means 1 bullet revolution for every 8"
1:7 means 1 bullet revolution for every 7"
This will affect the bullet speed and stability when exiting the barrel. The shorter the barrel, the tighter the groove spiral.
As far as twist rate goes, this chart best explains which twist rate barrel is best for a specific 5.56/223 bullet grain
Trigger
Most out of the box AR15 will have standard mil-spec single stage trigger with about a 9 lb trigger pull.
The user can swap out the factory trigger with an aftermarket trigger at any time to improve overall performance of the rifle.
An upgraded trigger pack generally reduces the trigger pull weight significantly down to 2 - 5 lbs , which gives the shooter super smooth trigger action for fast follow up shooting or better precision shots.
Full Auto Trigger - Only available for legal registered NFA full auto AR15, Hard to find or buy for most people
Single Stage - Recommended for high speed competition shooting. No pre-travel, short reset & crisp trigger break
2-Stage Trigger - Recommended for long range shooting, where it gives the shooter less finger tension on the trigger prior to the steady trigger break as light as 2.5 lb
Muzzle Device
A muzzle device can minimize muzzle fireball, counter recoil & reduce unwanted muzzle rise.
All AR15 muzzle devices are standard 1/2" -28 thread pitched. The most standard is the A2 birdcage flash hider with the main purpose to reduce muzle fireball signature.
In order to reduce recoil & muzzle rise, the user can buy various muzzle brakes & compensators. These have specifically shaped ports and chambers machined into the muzzle device to redirect the hot gas as soon as the bullet leaves the barrel to minimize muzzle drift, climb & recoil.
Gas Block
For a direct impingement system, the gas block holds the gas tube in place. As long as the gas block fits the barrel and clears the handguard, then you're good to go.
There are three different gas block diameter specs:
- 75″
- 825″
- 0.936"
0. 75″ is the most common size, but always measure the barrel if you aren't sure while doing custom upgrades or build
The gas block quality and the size of the gas port must be carefully matched to give the rifle the best performance for cycling and when using a suppressor.
To go a step further, an adjustable gas block is recommended for managing the gas performance based on ammunition types and the use of a suppressor.
Buffer Tube
The buffer tube retains the buffer and the buffer spring, and the butt stock slides on it.
Most buffer tubes are machined with 6 position slots for having a retractable stock, but there are two buffer tube sizes:
- Commerical (1.170" diameter)
- Mil-Spec (1.14" diameter)
They don't havy any signification functional difference, but Mil Spec stock can't fit on a commerical tube.

Charging Handle
Most AR15 comes with a standard left-handed charging handle with a small latch, but you can replace it with an Ambi charging handle featuring a larger latch for more leverage & more gripping room.
It makes charging the bolt & clearing jams so much easier.
