Ar15 build setup-How I fixed my accuracy issues with my first Ar15 build. My first Ar15 build didn’t quite go as planned. I was trying to build an extremely accurate /precise 16″ inch Ar15 and I got a 2-3 moa rifle. I have managed to shrink the groups and I’ll go over how I did it in the video and what I did to get there.

Comment below about your build and what problems if any you ran into during the build process.
I put together an upper with the exact Rock River barrel you ended up with a couple years ago. It’s the most accurate ar I own hands down it will shoot 1/2-3/4” groups all day with the best group so far just under 3/8” with my hand loads. I almost went with a criterion barrel myself I’m glad I went with RR its a shame their customer service is non existent would like to see a follow up if they contact you.
Absolutely love her in the background! That’s awesome!
I once bought an assembled upper with a stainless fluted barrel. The best it could do was 2” groups at 75 feet regardless of ammo. Scrapped it.
This is my rifle this is my gun,this is for yootoob is that any fun?
Interesting, I also found that the IMR 77gr razor core ammo produced significantly better groups in my LWRC IC-SPR. Unfortunately its significantly more expensive than competing mfg.
Do you still have the original barrel?
Great video! Thanks for your educated
Nice vid, but I was hoping to see some troubleshooting. I understand about the cost and time. I have my 4th build, a 6.5 Grendel. It will not group at all. Hoping it's my muzzle device. Its a weird forward gas shooting break. It didn't dawn on me until I was shooting yesterday to take it off and shoot a group. I didn't have a wrench with me to get it off though. I will try it and see what happens..
Disappointing to hear about criterion. They have always had great barrels
The barrel has the biggest affect on precision. Good video.
If you want to sell the barrel and gas block, I might know a guy… 🙂
Glad I seen this I just put a criterion 18” in my bag. I don’t wanna deal 0%customer service if I have an issue. So many people seem to swear by the criterion hype. Thanks for great content 👍
On top of all the good you do I appreciate the fact that you show that you face the same challenges we all face, then show your subscribers that you use the comments to better yourself. Good stuff
Thanks for making an update video!
Awesome video
I'll sit and watch the build video when I can, I know you might have answered this on the previous video, but which mount are you using there?
now you can do a 2nd chance build for that barrel, haha
chasing those tight groups! haha thanks for all the help!
Great video we want more accuracy study like that
I had a rifle from PSA that didn't shoot worth a damn. Changed the barrel, even worse. Hand loads and factory. What did I do…
I found a cheap set of spacers on Amazon for the muzzle device. And then I tuned it. I threw a bunch of them on, tested, them I'd drop a .004 or .007 spacer until I got down to a one inch group. Being a 4 prong muzzle ( mine is three prong ) timing shouldn't matter.
Full disclosure; the load I was testing works great in another rifle I built up for my son.
Like you I dealt with the barrel nut, took the muzzle device off, I did all of it. The only thing that worked was tuning.
helpful, wife big help. thanks
Great video. I await the new results.
Have you shot it any further than 100 yards?
Glad you worked out with a new barrel. Great cheerleader shot confirmation support also.
Do keep trying criterion for service. And I wonder if you re-mounted the barrel you'd find the criterion to shoot a lot better, suddenly. A lot of people on their first build don't know to "set" the threads by torquing the barrel nut on, backing it off, and torquing it back on a few times to send it home truly (sorry if you did this, I haven't watched your first build video before posting this comment). By taking off the old barrel and installing the new one you may have inadvertently corrected this.
Either way you did a good thing by losing the Geissele snake oil gas block. Not enough people know that those are made of crappy MiM alloy and have horrible quality and QC, and they sadly assume that because it's high in price it's a good product.
Sad that there was a chance it was the criterion barrel. They're so expensive
I hate when a rifle doesn't group well. It can drive you crazy. Glad to hear you got it sorted out 👍
Indeed you are very lucky to have a "cheer leader" wife! I couldn't get my wife to the range if I knocked her out and drug her there !! Maybe your wife will want to try shooting for herself .?! Kudos to your better half !
Great content as usual, sir! Thank you!
