Stratus M-Series Barrel, .223 Wylde, 18″ Barrel, 1:8 Twist, Fits AR Rifles, 1/2×28, Rifle Length Gas System, Bead Blasted Finish SBBL18SPR
This is our M-Series 18 inch, SPR Profile, Rifle Length, .223 Wylde chambered barrel. Machined from 416R stainless steel with a bead blasted finish, and features a FailZero Nickel Boron Coated M4 Feed Ramp Extension. All of our barrels are High Pressure Tested and Magnetic Particle Inspected. This barrel features a longer .750” profile dimension necessary for proper installation of the OPS Inc 12th model collar and suppressor.
We chose the .223 Wylde chamber for our M-Series barrels because you can fire .223 ammo without giving up accuracy and 5.56 ammo without worrying about excess pressure. The .223 Wylde has the same chamber angling as the standard 5.56 chamber, and it also has a .2240 free bore diameter. What you get, is a chamber that is designed to handle the higher pressure of the 5.56 load while maintaining the accuracy of the .223 cartridge.
All Stratus barrels are guaranteed to give sub Minute of Angle (MOA) accuracy with match grade ammunition.
