Sionics with RGP barrel, or even the extreme reduced version if it’ll always have a can attached.

Nice spreadsheet!
Fantastic information Sir.
I run 10.3’s and 16’s. I’ll do more research into Sionics and Triarc.
.052 on a 11.5? Hmmm… I like the sound of that.

Off topic, If my guns were shooting like that, I would let KAC look at them.

My SR-25 is just super picky with ammo. I can get ~1 MOA with FGMM (168 gr and 175 gr) and have slapped steel at >1100 yards with an M118LR clone before, just haven't found a good hunting/duty round that will group well, whether it be factory or reloads. Closest I've gotten is Federal Terminal Ascent 175 gr at about 1.5 MOA, most other stuff is 2 MOA and over. I was able to find some Prvi Partizan Match stuff to use for plinking when I need to do more than just hose IPSCs at 10 yards that'll maintain <1.5 MOA and wasn't terribly expensive pre-pandemic.

My friend's LPR did go back to KAC, hence the diagnosis about the gas port burr. With the burr removed, it's also still picky with ammo; it prefers lighter bullets, and he's unable to get it sub-MOA with heavier bullets (1.1 MOA with his favorite 77 gr TMK handloads that he can typically get 0.75 MOA in his other precision gas guns).

Has anyone experienced the Geissele 11.5 SD gas pressure (suppressed & unsupressed)? Overgassed, undergassed, just right?

Outstanding with a 556 RC2, makes the stock 11.5 BCM seem like a piece of trash in comparison

I have an 11.5" Duty (not Super) with an G42 spring & H2 buffer. No experience suppressed yet, but with a flash hider, I'd say it's about the same as my Colt 14.5" SOCOM barrel with the same spring & buffer. I don't find it disagreeable at all.

I’m not sure if they’ve changed anything, but a buddy got one pretty early on, and it ran very nicely. It was not objectionable with the Chimera, but he did end up choking it down with a BRT EZ Tune, since its a dedicated host. Stock, its probably one of the best gassed 11.5s around, in that one sample.

Just right
