I ran three different 11.5's, and LMT, DD, and a custom one and NONE of them would lock the bolt back on the last rd. using the H0 buffer and vltor spring. I swapped lowers to the super 42 and all of them worked 100% as usual. So, to me using it on any of my 11" guns is a no go. I tried three different mags as well and also tried higher pressure ammo and still did not lock back. Super 42 locks back on even 223 Remington ammo. But the A5 works on my 16" LMT fine.
Grab the Geissle next week on sale.
For starters I would never use an H0 in any SBR. There are a gazillion threads on this forum that all point to an H2 or H3 (depending on if you’re using a can or not) and that system working 100% of the time - unless there’s some underlying problem. I’ve used A5’s in almost every build from AR-15’s to AR-10’s, all 100% functional as long as I do my part in using the RIGHT parts and they are also quality parts. In the rare case where I was used an adj. GB, making sure it was tuned correctly. I’m not talking about 2 or 3 but upwards of 10 SBR’s that except for a couple that used a PDW stock and had a proprietary buffer/ spring were all A5 setups and run flawlessly.
So if you are trying to use an H0 in a 11.5 and I’ve owned a couple few 11.5’s, I would say that’s more operator headspace and timing and you did not use the correct buffer. A common setup for a short barrel setup is an H2/3 & Sprinco Green spring, but I’ve had solid success using an H2/3 with the A5 rifle spring.
Spending $50 on a spring when a standard rifle spring works makes zero sense to me as does using an incorrect setup as a basis for recommending other parts the OP need not purchase.
ETA: most of the BCG’s are enhanced LMT’s with a Sionxics bolt completion kit or a standard LMT bolt from an L7D3 BCG.

Just responding to the several comments directly above, are you responding to my questions or other comments in the thread?
My specific question is, Noveske G3 receiver set is a little out of spec, as is the LMT E-bolt and the PWS E-buffer tube. Aside from being mildly out of spec does anyone thing those parts may conflict with one another.
Aside from that question I’m running an over gassed Noveske Afghan 14.5” barrel with an adjustable gas block and plan to run a Geissele Super 42, probably with an H1 buffer. I think I’ll find enough pressure to cycle, maybe a dwell issue if I was to run full auto but unfortunately I don’t have that problem.
