Not super well versed on 300blk but I would like to expand

Here’s what I’m looking for

8-10” barrel
Side folding stock/brace
Can run both subs and supers while being suppressed all the time.

Bonus if it’s FRT/SS compatible


What checks the boxes

No problem using supers out of the 1/5 twist?

It looks absolutely awesome I just don’t have a ton of faith in sig. from what I have seen on forums and guntube it’s hit or miss

For the price they command it should be really close to perfect.

Maybe I’ll wait and see if a bren 3 ever shows up here

My buddy just bought the cane break it’s 5.5” we shot it with a can subs and supers no issues.  They make beautiful rifles

If you love your suppressor, go with the shorter 6.75” barrel. Supers out of the 9” are pretty much limited to $olid copper bullet$.

JAKL checks all of those boxes. You'll need a slip trip kit for it to run an FRT - https://palmettostatearmory.com/psa-jakl-300-blackout-pistol-flat-dark-earth.html

I've been liking B&T lately.  APC300 or SPR300 would both do me nicely.  I'll have to see how much overtime I get this spring.

Older thread I realize.  

My advice: just build your own.

I've done several and have been nothing but pleased and enjoyed the process.  

One has an 8" barrel and its been tunned it nicely for supers.  Just because I wanted to.

I also did a 16" for subs (made during the brace ban, but the longer barrel is quieter regardless) and it runs supers fine, just kinda harsh.

Supressors go on everything for me.

You could get a Riflespeed adjustable gas block and adjust on the go as your ammo changes.

Building an AR is not hard, I assure you.
