224 valkyrie build

What buffer works best with it? Some places say the carbine one is fine, others say H1. Same with the tube. Carbine or rifle length?
TIA

[knockonit]

mine runs fine with carbine buffer, no issues with over a couple hundred rounds

Cool, thanks

In for the shooting test Cappn, I was considering Valk awhile back

Proper buffer weight is largely dependent on barrel weight (mass) WRT bolt bounce. Heavier barrel = heavier buffer. The other primary factor affected (dwell time) depends on the size of the gas port and the relation of GP to barrel length.

Why would the weight of the barrel affect buffer weight?

Science!

The effect of bolt bounce is due to the BCG slamming into the barrel extension and then partially coming ("bouncing") out of battery and then settling back into battery again. All else being equal, a heavier barrel recoils with more energy, thus requiring a heavier buffer to counteract that recoil.

For example, the H2 buffer was created / implemented specifically for the the M4A1 SOCOM carbine, which has a much heavier barrel than the standard M4, to ensure reliable full-auto fire. In that case, the change in buffer weight was solely due to the heavier mass of the barrel. It wasn't a dwell-time issue, as there were no changes in the gas system or barrel length between the SOCOM and standard barrels.
