AR15 Gas System and Buffer Basics

We received a request to talk about the gas system and buffer of the AR15. Those two parts make up a lot of the functionality of the rifle so we talk about the basics in this video. We may go in to more detail in a future video, if that interests you please let us know!

Thanks for watching!

This is one of the many videos I watched before attempting my first AR-15 build. Thank you Dave for recommending the H buffer (or H1) for my 16" mid-length barrel, my gun shoots/cycles like a dream. BCM upper, American Defense BCG, 16" Ballistic Advantage .223 Wylde Hanson Profile barrel, VG6 Epsilon compensator.

Would be nice if someone had a chart for different barrel length with the different buffers and spring combinations.
For the difference also in calibers rate of twist annulled weights.

This could have been helpful to have watched before building my AR.

I just got my first AR a couple weeks ago and have been researching everything on it, this channel is so helpful, will not take it to the range till I can break it down and clean it know all about it, videos like this will and is helping me so much, Thank you sir!

Thank you for explaining how the basic gas system on an AR works. So many of the youtube AR 'experts' have no concept of a locking bolt and what the gas actually does. This should be mandatory viewing for about 98% of the so called AR experts on YouTube,

[TexasTrained]

You are very good at explaining everything in a manner where all of " US Dummies" can understand and comprehend it. As well as the "Newbies" just getting started.I very much appreciate your expertise .Ive learned quite a bit here today...Many Thanx

Excellent video. I have been looking for a gas system tutorial this thorough. It's perfect for a beginner.

[Sparkymark]

Thank you for this video, building my AR and this video was extremely help in knowing how all the components come together to make it shoot properly.

[cotajesus]

this is the best explanation i have seen on gas systems and buffer weight

I would really like to see an in depth video on buffer systems for 9mm ar pistol builds. As for proper weight of buffer for good cycling and spacers to be used to prevent bolt catch shear off (reduced return travel velocity).

[frostydabear]

Really great video. Very informative even for a short "quick cover" of the topic

[jayryan]

This is the greatest explanation on how the gas (and blowback) system works in an AR. Thank you-just subscribed!

[herman]

Very informative, thanks for posting. Never gave the buffer system a second thought.

[anthonyshepard]

I would like to see more about buffers and buffer Springs in regards to AR-10/ lr-308. 🔫🇺🇸🔫🇺🇸🔫🇺🇸🐢

[masteryoda]

Thank you for sharing this video it really helps people who are new to this. Thanks again

[alallan]

I love this, please teach more on buffers and gas systems. I build and want to know about buffer weight-light weight BCG's and variable gas block interactions. Thank you Dave, great video !

The carbine gas system is actually optimized for an 11.5" barrel, as on the Colt 629 carbine. The reason the M4 has a 14.5" barrel is the need for space in front of the gas block to mount a bayonet.

[jagman]

Some good information here! Great video, well spoken and straight to the point! I want more!!😀. Keep em coming!

[kentuckyjustice]

I'd love to see more on buffers, springs, and how they affect the most popular calibers commonly used with the AR platform. Now, THERE'S an encyclopedia's worth of videos. Thanks.
