Criterion Barrels: 12.5″ Barreled Upper Receiver

While I’ve had and shot a lot of different ARs, this 12.5″ barreled upper receiver by Criterion Barrels was special. Not only was it probably put together with the most attention to detail of any rifle I’ve owned, but there is a cool back story.

While it started its life as a old school Mega Arms billet upper receiver and a 10.5″ Noveske Stainless Steel Barrel with NSR Handguard, it changed a lot…

If you are looking for a barrel for your next build, whether it is a AR15 or a Remington 700, check out Criterion Barrels, they make some great stuff.

You can find Criterion Barrels through Brownells.

While the original configuration wasn’t bad, it definitely got more accurate and nicer to shoot when Criterion got ahold of it…
It’s final configuration was awesome.
