I just put a DD 10.3 barrel with a SLR gas block on my 12" OBR upper.
The barrel shoots MOA with 69gr fgmm and under 2 inches with PMC. Its honestly becoming my favorite "rifle" in the sable, as its rocking an SBA3 brace so technically a pistol.
I normally pack a tOBR broken down in a backpack on long trips, but this time just broke the pistol in half and tossed it in, and must say, at the very least, its my new trip gun.
Just set it up with some NV optics for a pig hunt I'm going on tomorrow and i can't wait to truly run it through its paces.
I can send pics if someone will host, but ultimately, it would be amazing if LT offered a 10.3 or 10.5. its literally perfect, and getting rid of the Big ol 12" factory barrel shaved almost a pound off, now the thing balances better that my KAC 11.5 mod 2
