  • 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!

      3ron made a comment that needed no solution and you tried offering one with a wild solution from left field. What in his comment made you think he needed a heavier buffer. Just because most AR's are over gassed doesn't support your reply.

      To be accurate you'd also need gas port sizes, primarily suppressed vs unsuppressed, environments, full pressure 5.56 vs low quality .223 etc. If you want the optimum buffer anyway. You can get away with a buffer that's a little light or a little heavy depending on your maintenance cycle and if you plan to shoot full auto.

    All my rifles are mid length 16”s. I only buy the carbine buffer kits because that is what I was told to pair it with. Some guys get a little OCD and they’ll tune the weight type to their liking but for a rookie like me I want reliability since I use all kinds of practice ammo, the cheaper the most likely picked by me.

    1st time viewer - new and instant subscriber. You have a great presentation style, and the information is not only first rate, but easy to understand and easy to digest. I have built a few AR-15s now, and most of this I didn't know. I just took quality off the shelf parts and I matched them up the same way that I would build a race car, which I do understand... I focused on buying quality parts, and I matched the buffer, gas tube, and stock extension to the barrel size. I also usually use an adjustable gas block so that it can be adjusted to the specific gun and the chosen ammo. It always worked out well, but I will definitely be looking for the follow up videos to this one. Thank you. The information that you provided today is as hard as hens teeth to find in one place, much less in a fascinating video like you have provided here today.

    A lot of people think the "carbine" gas & carbine buffer are related. The buffer length can be rifle with carbine gas, & visa versa, and both will function reliably done properly, (buffer weight)... Rifle buffer systems are just full length, non collapsible, carbine tube & buffers are short. Some timing , speed, recoil etc will change a bit, but both will "function" fine..

    Just a suggestion: if you prefer not to run an adjustable gas block (they all eventually carbon weld) - contact SPRINCO, tell them about your specific combination - and ask them what spring and buffer their customers are using. For about $30 you can get custom improved chrome silicon buffer, ejector, and extractor springs that will make your AR run great, eat everything, and not gouge your brass.

    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.

      Incorrect. Those cuts are to mount an m203 grenade launcher. Those cuts became obsolete with the m320 grenade launcher by HK

    YES! This is a great video. I’ve only had one system problem and it was on a suppressed gun. The gunsmith didn’t explain it to me. GOOD Gunsmiths are a rarity. If You find one, go ahead and shackle one of Your legs to His. There are a Lot Of hacks out there!
