Whether replacing a shot out AR15 BARREL or purchasing an AR15 BARREL for that new rifle build proper selection is important as there are several factors to consider
- BARREL LENGTH
- GAS SYSTEM LENGTH – Carbine, Mid Length and Rifle
- BARREL MATERIAL – Stainless Steel, Chrome Moly, Chrome Lined
- BARREL FINISH
- BARREL PROFILE
- BARREL WEIGHT
The list below is in no way a complete list of every AR15 BARREL manufacturer. It is more a list of what is commonly available yet coveres the full spectrum of options.
ARMALITE AR15 BARRELS
ARMALITE AR15 M-15 A4 RIFLE BARREL STAINLESS STEEL NATIONAL MATCH BARREL ASSEMBLY
ARMALITE AR15 M-15 A2 CARBINE BARREL ASSEMBLY
ARMALITE is the “AR” in AR15. It is Armalite that brought the EUGENE STONER design to the world. It’s no surprise that they offer a wide range of AR15 BARRELS to suit any shooters need whether that need is WAR or HIGH POWER COMPETITION. If standard Armalite barrels dont excite you feel free to give their Premier Services Division a call for a spare no expense AR15 COMPETITION BARREL.
CMMG AR15 BARRELS
CMMG 14.7 inch M4 5.56 Barrel Assembly with Permanent Flash Hider
CMMG offers what I would consider commercial grade Milspec AR15 BARRELS. CMMG while not a favorite of AR15 die hards, they fill the need for quality, value and top notch customer service. Also CMMG is very quick to market and good at servicing niche calibers such as .22LR, 9mm, 300 BLACKOUT, 308 AR and of course 5.56 NATO. I personally own a CMMG SIERRA .22LR UPPER RECEIVER as well as a CMMG AR15 9mm UPPER RECEIVER.
COLT AR15 BARRELS
COLT M4 AR15 BARREL
COLT with it’s AR15 production being mostly geared towards decades of military contracts leaves little AR15 BARREL inventory for civilian purchase. Those that are lucky enough to come across genuine COLT AR15 BARRELS should consider themselves lucky to get some of the finest battle tested military grade barrels available. Despite internet naysayer’s COLT AR15 PARTS are premium quality with a premium price tag.
Living in Connecticut the home state of COLTs MFG as well as other firearm manufacturers I have heard rumours that COLT AR15 BARRELS are produced by another once local firearm manufacurer as well as possibly a Connecticut based barrel manufacturer. I have not been able to verify either rumor.
Daniel Defense M4 AR15 Barrels
DANIEL DEFENSE is mostly known for their QUAD RAIL/FREE FLOAT HANDGUARDS but they also produce a wide array of COLD HAMMER FORGED BARRELS in various lengths and contours. While I have no first hand experience with DANIEL DEFENSE BARRELS I have read and a lot of discussion on the M4 variant. The most common comment is the GAS PORT needs to be drilled to 1/16″ as DANIEL DEFENSE appears to ship the barrels with a gas port about .004″ undersize at .059″ instead of the Milspec .063″.
The barrels are stated to be very accurate.

Cold Hammer Forging of barrels has been known for decades to produce the most accurate, longest lasting rifle barrels obtainable. The Cold Hammer Forging of barrels is accomplished through intense hydraulic pressure applied at opposing angles by carbide steel hammers. During the hammering process, a mandrel is inserted into the bore while the carbide steel hammers shape the barrel around the mandrel creating the chamber, the lands, and the grooves. In addition to the aforementioned benefits, the Cold Hammer Forging process creates a defect free bore and the most consistent chamber possible.
All Daniel Defense cold hammer forged barrels are made from start to finish in our state-of-the-art facility located in Black Creek, GA. In keeping with our heritage of not cutting corners, all cold hammer forged barrels feature a forged chamber and heavy phosphate exterior coating. They are all MP tested on-site and are available in multiple configurations which includes barrel only (stripped); barrel with Front Sight Base; barrel with Low Profile Gas Block; and barrel with Front Sight Base, gas tube, and delta Ring assembly (Complete). These barrels will prove themselves to be more accurate and last longer than a barrel that has cut or button rifling.
