Sharp Looking 223 AI Build

Sharp Looking 223 AI Build

Tom D. of Colorado sent us some pictures and info about his 223 AI build using a Criterion Barrels Inc. barrel and Zermatt Arms Origin action purchased from Northland Shooters Supply.

Here are some of the components Tom used on his build:

  • 24” Criterion barrel- varmint contour- 223 AI- 8 twist with muzzle thread
  • Zermatt Arms Origin action- competition bolt knob
  • NSS squared and trued barrel nut
  • Periwinkle H-357 Cerakote finish on Action, barrel nut, and thread protector
  • PT&G 223 AI headspace gauges
  • NSS Thread protector
  • TriggerTech Special flat trigger

Here is what Tom had to say:

“I ordered a number of parts from you to build my 223 Ackley Improved rifle. From the smooth Zermatt action to the barrel and everything in between, all the parts you supplied were top-notch and fit perfectly. The rifle is shooting 1/2 moa and will only get better. I’m really impressed with the Criterion barrel. I have included several photos of the periwinkle color and I am extremely pleased with the cerakote job. Thank you again for helping me create this rifle. I used 55gr FMJ-BT to break the barrel in and also used the 55gr 223 Remington rounds to fireform the brass to 223 Ackley Improved. When I get a sufficient amount of fire formed 223AI brass I intend to load .224” Sierra Matchking 69gr HPBT-Match bullets.”
