If you can afford it.. get one of each type of H buffer.
Reason: Because for some reason my BCM 14.5middy get really picky about buffer weight depending on the ammunition used.
example:
Winchester white box (Q1331a i believe) will not cycle properly with an H buffer in my rifle.
Lake City will.. go figure.
I'm sure there's a very cool and interesting reason that it does this and one of these days I'll address it.
For now ,,, I keep a normal carbine buffer along with my H's in my range bag.
