300 whisper vs 300 blackout

The benefits to using the Blk are that if you want to run sub loads or standard velocity are the simple change of a magazine in AR platforms.
If you have a 300 barrel in 8 twist or even 7. You can run 130 grn or 208-220 grn loads. 130 grn is bad for hogs .
 
We have a CMMG 8" barrel with gas tube and gas block, in stock. $299

As well, we have a CMMG complete 8" upper with a Midwest Industries rail. $699

Rich

PS, the 8" barrels are ideal for all 300 AAC rounds. However,, the 16" barrels do not function well with sub-sonic ammo.

So, if you want the best of both worlds, get the 8" barrel.
