Hey guys and gals,
After a lot of research, and a lot trial and error with my own AR-15 pistol build, I made this video to help anyone that is wanting to build, or maybe already have built an AR pistol, troubleshoot any problems that may arise after you have your gun assembled.
These guns can be very finicky, and if you’re not familiar with some of the problems that can be tossed in your lap, you’ll not only be caught off guard, but frustrated as well. I hope this video helps anyone with any problems they may be experiencing, or with any questions you may have before diving into a build. If you have any questions, or comments, don’t hesitate to ask, or share your experiences, and knowledge. Thanks for watching, have fun, and be safe!
Oh yeah, and try to guess how many times I say the word “Gas” in this vid. LoL.

H3 with the Geissele braided spring 😎👍
Thanks for the video! This really helps with my under gassed 10.5 AR15.
Hey so I just did my first AR pistol build and I shot it today and when I pressed on the trigger once it shot like 6 rounds instead of just one, almost like a bump stock. Any solution?
so why don't you just address using the correct buffer tube (weight) and spring for size barrel on your weapon.
What’s the best buffer weight and spring strength for a 10.5in barreled 556
Great video. OMG. Best I have seen yet. My problem is a bit different concerning my new built AR pistol. Using a light load of a 125 grain bullet, my pistol cycled great, but when I tried using a 220 grain subsonic bullet, I started having issues by "blowing out" primers, not often, but a few times. I have a "Tunable" gas block and I believe is adjusted properly. The primers landed inside of the trigger well causing the primer to jam the trigger assembly. Please help..
ive had an Aero Percision 7.5" in 556 paperweight for 4 years now. from aero it has never worked. will not extract.
What type of pistol brace is that?
I put together a Delta Team assembled 7.5 upper on an Anderson lower, but added a folding pistol brace. The folder comes with a 3.1 oz. spacer. With 40 rounds out, it extracts, but I have never seen an ejection. Thinking it must have been under gassed , I took wt out of the buffer, but nothing changed. So now I am totally confused. Guess I better start thinking it is over gassed, not under. Ideas ? Advice ? Many thanks – great video !
Issues with magazines going in, magpul, used to slide in no problem. One day tried to put mag in and it is a bear. It goes in but takes multiple tries or slow constant pressure. Any insight
Great vid the information you shared was very helpful and understandable.
Does the grain of the round have an effect on the double feed/ or over gas issue
Sounds like a piston system is better
I have a problem where my ar pistol 8" brrl will shoot one time not eject the cartridge then lock up where it's really hard to clear the malfunction. I have a Fail zero NB Lightweight BC. 8" Barrel. Standard mil spec lower and upper and buffer weight and spring . I don't think anything is misaligned cause I paid to have my upper built and assembled by the company.
So will an adjustable gas line solve all these problems?
Thank you brother that was a big help
g54023 – I have never had a failure to eject, sometimes it happens a little too soon, but boy does it happen!!!!!!!
g54023 – I have had a few failure to extract scenarios, and boy did she get pissed, well, her husband was more upset than she was on the day the baby was born. The baby had red hair, like mine…Buahahaha!
g54023 – I have excessive gas issues, well, when I eat jalapenos that is. But a few Tums and I am good to go!!!!!!!!
If your overgassed Go straight for the adjustable gas block. A different bolt is $100+ a high pressure spring is $40+, an h3 buffer is $50+.
A good detent click adj gas block is $85. Why would you start with things that might fix it when an adjustable gas block WILL fix it!

Great video. Thanks!
So I have a 7.5" upper and it's .223/5.56. It doesn't lock open after last round shot. It feeds and shoots and ejects fine. The carbine buffer spring feels weak and the bolt has no marking. But I eject at about 3 o'clock. So I've bought a colt carbine buffer spring and a Wolff extra power spring. Gonna run a colt H3 buffer too and I hope I'm good to go. I'll come back and share my results after it's all done.
