Criterion Barrels: 12.5" Barreled Upper Receiver

[@Deuce_Dufresne]

I just installed a 12.5 Core barrel in my SBR and replaced my old BCM barrel with a 16” Core barrel. Big fan of Criterion.

That long-winded explanation was one of the most helpful things I've ever heard with regards to proper ar fitment and proper gas system operation. Thanks. Will be very helpful on fixing some issues with my PR AR15.

Criterion Know the business. I've had the pleasure of speaking with Mike and I learned a great deal from him. I use their method of accurizing with trueing the upper receiver. My only complaint, and it's not really a complaint, is the 18 inch I have is faster than any of my other 18 inch barrels, bad thing, no but allows for an incredibly accurate barrel with handloads. Great Vid

@Frank Tank This is true, that's why I built a 12.5 rather than 13.7 haha

[@josephsantana3094]

@Frank The Tank I've been seeing a lot more 13.7 owners coming up on social media lately. I almost never see 14.5 owners online or in person. And for shorter pistols it seems a lot of people go 10.5 or 11.5 rather than 12.5 (even though I think 12.5 is better). The 12.5 actually isn't as popular as it should be.

Criterion has a great reputation for accuracy. What I really appreciate is that you gave us what you got on that day.What you see is what you get, warts and all. That takes balls.I understand you have shit to do or may never be inclined to ever find THE round this one likes and record a good day behind this rifle, but, everyone likes a comeback. I also respect ,you may feel that it does what you need it to do and never needs to be revisited.Shout out to Criterion for putting together a cool build for you.

[@monkeycbrown]

What I find interesting is that every single AR-15 I have which consist of 11.5 and several 16 inch all have the cam pin slot has some wear. On my 16 inch, I do not run suppressors and all of them have an ejection pattern of 4 O'clock with running an H2 buffer with sprinco blue spring and some with the Super 42 with H buffer. The 11.5 has VLTOR A5H@ with sprinco green spring with 3 O'Clock ejection pattern so it might be a little over gassed ( I also ran a sprinco red spring with H3 buffer and same ejection).

12.5 is my go to length . I just built a BA 12.5 with a cloud defense COR2 rail & BA upper/lower & barrel & love it . That 12.5 is just so nice , being short , but still giving you enough dwell time to be effective at a little distance.

[@ComeOnPelican91]

dwell time is a phrase associated with the bolt and gas port; just say velocity

[@johnneill5960]

ComeOnPelican91 no I prefer dwell time thx . Ya know the extra length added from a 10.5 to 12.5 allows the projectile longer dwell time to travel along the bore which In turn leads to added velocity. But added dwell time allows for velocity. Thx , I'll take I was EOD for 1000 Alex .

Great video. Always easy to watch and follow all the info and keep it applicable even for us Jarheads. If I may ask (because I’m considering sending a barrel to ADCO to cut to 12.5”), any consideration or discussion of mid length gas system on the 12.5”. Idk, but from what I have read/KZbin learned, it’s reported to be softer shooting then the carbine gas system. May be splitting hairs and inviting needless gas system and buffer weight tweaking just for slightly softer/flatter shooting at the cost of the utter reliability that carbine length gas provides. However, the email went into a great deal of explanation about mods made to lessen the abuse of an “overgassed” and suppressed carbine gas length AR. So I’m trying to learn (not question) why Criterion went with the carbine vs mid gas length. Semper Fi

[@cardwell88]

I just got my 18" criterion and so far I have determined it absolutely hates 55gr. Best group I got was 1.1" but that was after shooting 2.5-4" groups all day with 55gr ball from various brands. I hope this is just a bit of a break in period. Going to try some match ammo next time.

Ya, I can't stand anything that needs to be timed...

[@5jjt]

My school of thought is to throw out the fliers. Although fliers can be caused by a barrel, but there's plenty of reasons to suspect the bullet too. Perfect concentricity of a bullet is needed, and this gets worse in open tips, and inserted metal penetrators. Bullets seem destined to have numerous fliers no.matter how well the barrel and shooter.

He got good accuracy with some loads, and worse with others.. that's how bullets work; some shoot better than others out of different barrels as each barrel is their own animal as with each projectile.
