Yep, another "what caliber SBR" for 10.5"

[adamsredlines]

Kinda wanna do another SBR upper. Have a 8.2" blackout and 12.5" 5.56, so this one will be a 10.5.

I already have full size rifles in those calibers as well as 458 Socom...so seems 458 is best bet? Am I missing an obvious choice for a 10.5 that's not covered already?

This just dropped, 458 would be pretty cash tho

I like my AK-V in 9mm that is 10.5". You don't have to stick with rifle calibers if you don't want to.

 

[adamsredlines]

I have a MPX in 9mm, so that's already covered.

10.5” is a little short, but I do like the 6.5 Grendel in 12.5”.

10.5” rock river 9mm barrel with A2 front sight post!

7.62x39 is handy to have around in a shorty too.

During this recent shortage, I really wanted to do a 350 Legend SBR.
Then S&W chambered it in a revolver and I was doubly convinced that it would be a fun SBR but I never actually took the turn down that road.
@Moparman485 did alot of testing with that round, IIRC.

It was interesting how much 350 ammo was available during the drought. If one already has an 8” 300blk for social issues and a 5.56 for shooting, 350 might be a good choice.
