Small Arms Solutions video: "The Buffer - Theory and when to Use What Buffer"

[17K]

Keep 'tuning' with buffers.

It doesn't matter like you think it does.

Most every AR in use in the entire world's military and police use an H or H2 buffer in everything from 10.3-20" barrels, suppressed, unsuppressed, M193-M855A1, semi, 3 round burst, and full auto.

But some guys on M4C have to tune up their A5 buffers with their own mix of steel and tungsten weights and special springs to get optimal reliability from their carbines?

Puh-leese.

This is exactly the misinformation Im trying to counter. Yet people are still trying tell me Im wrong.

Cajun what matters is the gas system length and gas port, not the profile of your barrel. You need to tell us the gas system length and the mfg of the barrel so we can roughly gauge the gas port size.

It's a 16" Colt barrel. Carbine length gas system. Gas port: .063"

It's apparent you've never read Colt's conclusions on buffers.

Colt says H.

You can run pretty much any buffer you want with that barrel.

H2 + springco blue or A5H3 + springco green is what I found optimal. The springco buffer springs are not required but a nice addition, you can just use plain USGI buffer springs no problems.

Cool. Thanks.
