The Geissele Automatics AR-15 16" CHF Chrome Lined Barrel in 5.56mm is a cold hammer-forged precision barrel built for shooters who demand reliability under hard use. Whether you're running a duty rifle, precision competition gun, or a go-to hunting platform, this barrel combines Geissele's proven manufacturing process with proven materials to deliver consistency shot after shot. Made in North Wales, PA, each barrel is precision-machined, cold hammer-forged from chrome molly steel, and subjected to High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) before it ships.
The 16" length strikes a practical balance for AR-15 builds—short enough for handling and transport, long enough to generate solid velocity and sight radius. The mid-length gas tube system works with the government profile and 1/2 x 28 threaded muzzle to give you flexibility in suppressor or muzzle device selection. The 1/7 twist rate is the standard for 5.56mm, stable across the full range of bullet weights you'll encounter in commercial and military ammunition.
Chrome lining is a time-tested choice for durability: it resists corrosion, simplifies cleaning, and extends barrel life in sustained-fire or adverse-condition shooting. The manganese phosphate finish on the exterior provides additional protection. The single dimple for gas block set screw means you can lock down your gas block without over-complicating installation.
This is a barrel for builders and upgraders who know that Geissele barrels hold their reputation. If you're replacing a worn tube, stepping up a rifle's accuracy potential, or building a new upper from the ground up, this 16" is a trusted choice across the shooting community.
| Barrel Length | 16" |
| Caliber | 5.56mm |
| Material | Chrome Molly Steel, Chrome Lined |
| Finish | Manganese Phosphate |
| Twist Rate | 1/7 |
| Profile | Government |
| Gas Tube System | Mid-Length |
| Muzzle Threads | 1/2 x 28 |
| Manufacturer | Geissele Automatics |
Yes. This barrel features a government profile and 1/2 x 28 muzzle threads, the mil-spec standard for AR-15 uppers. The mid-length gas tube system is also standard. You'll need a mid-length gas block and tube if you're building from scratch.
Cold hammer forging aligns the grain structure of the steel, improving durability and accuracy potential. Chrome lining protects the bore from corrosion and speeds up cleaning—particularly valuable if you shoot in wet conditions or plan sustained fire sessions.
The 1/2 x 28 threads accept any standard AR-15 suppressor or muzzle device designed for 5.56mm. You'll need to install an appropriate muzzle device or adapter.
The 1/7 twist is the standard for 5.56mm AR-15 barrels and stabilizes the full spectrum of common 5.56 loads, from light varmint rounds to heavy match and defense ammunition.
