UNRIVALED | UNB-223WYLDE-16.69 - 16.69″ Rifle Gas Barrel with Bolt
The Ultimate AR-15 Barrel. UNRIVALED went all out to make the ideal barrel for the AR-15. After years of experimenting UNRIVALED crew settled on these features to fulfill their preferences:
▪ Rifle length gas system
Rifle length gas system for the best reliability, accuracy, and low recoil. Nothing beats how a rifle length gas system shoots. There have been some 16″ rifle gas barrels but we felt that the dwell distance was just too short. The extra .69″ delivers approximately 25% more dwell distance vs 16″ making it dead reliable with a wide range of ammo, conditions, and carrier/buffer weights.
▪ Heavy profile with aggressive fluting
Maintains the accuracy and rigidity of a heavy barrel with reduced weight and increased surface area for cooling. Flutes start after the chamber area to leave as much material as possible there.
▪ .223 Wylde Chamber.
Commonly accepted to be the best of both worlds for accuracy and the ability to fire 5.56mm ammunition.
▪ 1 in 8 twist rate.
To stabilize a wide range of bullet weights.
▪ Chrome lined.
Tto vastly increase service life under heavy use. Expect it to last twice the round count as a stainless steel match barrel.
▪ Hand lapped to maintain precision accuracy.
In general, chrome lining is known for fantastic durability but not the best accuracy, this maintains match grade accuracy.
▪ Headspaced BCM bolt included with each barrel.
Barrels will work with any AR15 bolt but these are matched to each particular barrel for extra accuracy.
▪ SubMOA
Sub Minute of Angle accuracy with match grade ammunition.
▪ Extra velocity.
The chrome lining, lapping, long gas system, and chamber/twist rate all contribute to slight velocity increases. Users commonly report velocities comparable with 18-20″ barrels.
▪ .750″ Gas block journal.
▪ 31.5oz weight.
▪ 1/2″x28 muzzle threads.
Highly recommended to use with an adjustable gas block. The gas port is sized to run any ammunition and carrier/buffer weight combo.
Essential part - CIP required with the system for which it is intended.
Sold only to holders of a permit.
