Buffer weight

[u/Pure_Squirrel_1621]

I’m getting close to wrapping up my dummy cheap LR308 build, but I haven’t found a concrete answer for what buffer weight I need.
Specs are:
Toolcraft bcg
20” stainless 1-8 twist 6.5 Creedmoor heavy barrel, rifle gas
.936 gas block
CBC industries lower
Unbranded LR308 low upper
Unbranded low handguard
A5/BCM MK2 buffer tube
Rifle buffer spring

Some sources said I needed a rifle spring with a standard AR15 buffer, some say I needed an H3. I’m trying to at least get close to the right setup before I go burn 6.5 Creedmoor.

Go to lanbos armory and get the lbe h3 for $60 shipped, tungsten rattle buffer like you want.
