C.J. explains how the buffer, spring, and receiver extension work together to cycle your rifle, manage recoil, and optimize performance. Learn the difference between buffer weights (H1, H2, H3), how to tune your rifle to address over-gassing, and explore popular upgrade options like hydraulic and silent captured systems.

I like this guy more than the guy that did the AR15 series.
Colt abandoned the hydraulic buffer because of costs and because hydraulic buffers will eventually fail. Which could cause an out of battery detonation and serious bodily injury. Granted, current hydraulic buffers will last for a higher round count, but they still won't outlast a dead-blow buffer weight.
The A5 Buffer System – A true upgrade. Explained here by Mike from SOLGW.
Absolutely fantastic explanation! Just one addendum: most, if not all, buffers are adjustable. You can buy the weights and mix and match the tungsten and steel weights as necessary. Just tap out the roll pin holding in the rubber bumper, remove the rubber bumper and you will have access to the weights. All the regular buffers, not the ones like the JP, have 3 weights in them. If it’s unmarked on its face it has 3 steel weights. If it’s marked with an H or H1, it has 1 tungsten weight and 2 steel weights. The number after the H describes how many tungsten weights the buffer has in it, the remaining weights (if any) are steel. The JP system is also adjustable by changing the weights. Like the spring, buffers do not last forever, once the rubber bumper becomes permanently compressed, it should be changed or the buffer should be replaced or it will damage your BCG. I did not know any of this until I took an AR-15 armorer’s course.
Thank you for this video!!!
i am a fan of the Odin, i use them pretty much on all of my builds. lots of rounds and they still kick butt
Telling me to grab my are wasn't a good thing. The people in the parking lot were not to happy.😊
Tnx bro 🤜🏻🔥🤛🏻

Is it just me but in the demo with the armaspec buffer on the cut-away buffer tube, it looked like there was a lot more recoil and muzzle rise compared to the normal spring and buffer.
In my case, I just went to test my build of a 10.3 with a H2 and a flow through suppressor which worked flawlessly with about a 4 o'clock ejection. BTW your video explanation is excellent.
