Consistent check weld pressure and consistent collar bone pressure with the stock lightly touching my neck is very important for semi auto. I’m assuming you already have a good straight back trigger press and hold.

Criterion CORE Barrel Accuracy Evaluation

Thanks for the write up! Just ordered a 14.5” from Criterion for my Tactical Games/Sniper Adventure Challenge build. What are people running for buffer/spring combos with this barrel?
My 18" CORE with rifle length gas cycles smooth and reliable so far with just under 200 rnds through it. Using the A5 & standard VLTOR buffer .

Just got my 14.5 Criterion Core together in a LaRue 2.0 Stealth chassis. Took it to the range to sight in my SAI 1-6 and was very encouraged by the results. First was a 5 shot group after taking a few shots to get on paper and then adjusting the scope. Group two was a 10 shop group I did in honor of @Molon directly after group one and another upward scope adjustment. Distance was 100 yards. FGMM 69gr OTM. I can live with this.
How was the fit of the Criterion Core barrel extension in the LaRue 2.0 Stealth chassis ??
Thanks! I used a Superlative Arms adjustable gas block. Ejecting at about 3:30. Recoil is the sweetest I’ve had without using a break. I had a Dead Air Xeno mount flash hider pinned and welded for a future Dead air Nomad suppressor. Standard weight JP Silent Captured spring. LaRue MBT trigger. Lantac E-BCG.
Thanks for the great discussions gents! I've only had great products from criterion and have been eyeing their new CORE 300 Blackout barrels. Can't wait to hear how they do but figure it's a safe bet that it'll be a knockout. It'll pair great with my 16" Hybrid in 223 Wylde set-up

5 round group at 100 yards
FGMM 69gr
NF2.5-10x42
The stick-on square fell off; I attached it below in the same orientation.
Seems to be in the 0.7moa range.
Rifle has less than 200 rounds through it.

Excellent post as always!
A question: Do you "break-in" new AR barrels in any fashion, or just shoot them to smooth things out?

Random questions: Do you ever use factory loads to do some of these tests? Also, what kind of firing schedule do you use for these tests?
For chrome-lined barrels, I typically shoot 200 rounds through them before doing accuracy testing. For match-grade stainless steel barrels, I'll do a very short break-in procedure to burnish to the tool marks in the lead and gas port.
