Hi,

I have a bcm m4 upper on the way along with an m16 carrier. Considering this setup what buffer would you recommend I run.

Will too much of a heavy buffer slow down the cycling too much since the added weight of a m16 carrier? or would a standard carbine buffer be too light? etc.

I am a newb when it comes to a-15s so please be nice:)

you need to explain what barrel length, what gas system length.

start with an H1 or H2...either are almost guaranteed to work

So somewhere in the middle like an H buffer will do? I have been doing plenty of reading here and there, but I figure I ask to see what people recommend considering my setup.

btw the lower is a spikes with DD lpk, magpul furniture, psa 7075 RE, carbine spring, etc.
