.355 - random 6 position carbine tube
.210 - BCM 8 position
.145 - Magpul 10 position
So the Magpul adjustment is roughly .065 (1/15ish) finer than the BCM. I say roughly because I did these right by the gun safe and the light wasn't optimal). I really can't say I've noticed any LOP difference.
I use Brownells CS rifle springs and sourced my A5 buffers through BCM as VLTOR was always out of stock. I use a A5H2 in my 16inch and an A5H3 in my SBR. I bought those based on forum searches, suppressed I'd probably be better off one higher in each rifle, but they function fine.
Good luck.
