I went 7.5" because as stated above not a ton of options for handguards when you get shorter. The X-Caliber Barrel along with a SLR adjustable gas block (I have it set not to lock back with subs without a can) and a Sig 762ti is quieter with sellier and bellot 220gn subs than my 9mm suppressed ar. The 7.5" is my go to now and I never really grab the AAC unless im hunting.
In regards to handloads, I went down a half a grain off my 16" loads.
OP don’t want to hijack your thread so I hope you don’t mind my question . It’s sorta related.
Hey Monk,
Since you own or have owned way more 300blk rifles than I have (1), I want to pick your brain.
I have an 8.3” 300BLK that has mostly been dedicated to subsonic suppresses use. I built it before BA started making 9” barrels 300BLK barrels, and I have had such a good experience with BA barrels, they have become my defacto go-to barrel more or less save a DD CHF barrel here and there.
But I want to build another 300BLK and use it primarily for supers. I want to take advantage of the very respectable ballistics I’ve seen from the 110gr (Barnes I believe) ammunition, but would rather not go out to a 16” barrel. Do you see value in going with something like a 12.5 or if I went with X-Caliber i think I could go 12” or 14”. It’ll probably be a mix of suppressed and unsuppressed depending on what in doing, but dedicated to supersonic ammo.
Thanks for any input.
