Wanting to give 300 blk a try, but I've only been able to find AR pistols that are far more than I want to spend on a lark, and 16" bolt/single shot rifles.

I know 300 blk is meant for short barrels, but would suppressing 16" rifle cheapen the experience?

*Edit*

To add to this, I'm talking about not finding anything in brick and mortar stores. Would prefer to buy what I can physically touch.

Are you finding 16” .300 BLK rifles in the local stores?

I built a 16” rifle with a Noveske barrel around 20 years ago. (ok, it’s technically a .300 FB barrel. The .300 BLK hadn’t been submitted/accepted by SAAMI yet, and JD Jones still holds the rights to the .300 Whisper name. But they’re all the same thing).

It has a pistol-length gas system, suppresses well, cycles supers and subs, and is more accurate than most of today’s run-of-the-mill pistol or rifle uppers.

Yes, I now also have short uppers on SBR lowers. They run fine too. The 16” gun is just a bit longer.

Ruger American Ranch 16" .300 BLK works great with subs and supers.




If you want a cheap way to get a bolt action .300 BLK and you have an AR-15,   The Bear Creek Arsenal bolt action uppers are cheap and functional if a little rough.  They shoot accurately.

.300blk is certainly capable out of longer barrels but just doesn’t make sense IMO. The whole point is good function in shorter barrels, you may as well shoot another caliber like 6.5G or 5.56 if you’re gonna go 16”.

PSA is the way to go.  If you’ve already got an AR you can just buy the upper from PSA for less than $200.
