mekks082 Posted August 6, 2021 Report Share Posted August 6, 2021 Hello all, new guy from the metro Colorado area. I found this page via google search when looking for some info about my current build. I have owned and built many AR15s. Even worked at Remington/Bushmaster for awhile on the line. This is my first AR .308 build, boy are these things fragmented! Anyways, here is my build list. Muzzle device is sitting in FFL jail with the Sandman-S (Hopefully it clears before it starts snowing.)

DNP Posted August 6, 2021 Report Share Posted August 6, 2021 Welcome from San Diego. Nice list of parts on there. Let us know how she functions. My bet is damn near flawless out of the gate. Did you by any chance measure the gas port in that criterion barrel- for informations sake? Quote Link to comment Share on other sites More sharing options...

That is a bad bitch! https://criterionbarrels.com/products/large-frame-ar/dpms-pattern-308-hybrid-barrel-mid-length-gas-chrome-lined/?v=7516fd43adaa They don't state the gas port, but it's a 0.750" journal. I know an 18" midlength 0.750" journal needs 0.080"~0.085" to run right (just run those at 0.085" and be done). Drop 2" of dwell time on that combo, and you'll have to bump it another 0.005" in gas port diameter to make it run. That thing needs to be running 0.090" on the gas port. My $0.02.

mekks082 Posted August 6, 2021 Author Report Share Posted August 6, 2021 Thanks for the warm welcome everyone! Will let you know how she runs once I figure out optics ect. 1 hour ago, DNP said: Welcome from San Diego. Nice list of parts on there. Let us know how she functions.
