300 blackout barrel length, Handguard length and suppressor

Mattj4867 · April 30, 2019, 12:26 PM

Hey everyone I’m currently contemplating a suppressor for a home defense build. I am going to get the rebel sos hunter suppressor for my 300 black out. Since the suppressor is modular and breaks into many pieces, would a long Handguard make it difficult to remove from the gun. Also what barrel length would be ideal for this setup

Thanks, Matt

AAC (who brought the 300blk mainstream) specs a 9” barrel on their SBR. I have one and it works great subs and supers, can or no can.

I run a gemtech 300blk suppressor for HD use with 110gn Blacktips (supers). Nice handy size and weight.

If the suppressor has multiple pieces that can unscrew from each other and do not have reverse threads to keep the suppressor together while removing it from the barrel, I wouldn't be sticking it under a hand guard.

9.5-10.5" seemed to be the sweet spot for .300 Blk, when I was researching.
I went for a 9.5" barrel and 6" hand guard. The hand guard could be longer, and still not cover the muzzle threads or suppressor; but I usually only care about covering the gas block, and the 6" hand guard did that just fine (while saving weight).

With a SilencerCo Harvester .300 attached, my overall barrel length is 17.75". ...Still reasonably short, and plenty handy.

Based on what I've read about the Rebel SOS-Hunter, I wouldn't spend my money on one. I wouldn't even pay for the tax stamp on one that was FREE.
Low quality. Poor fit and finish. And short lifespan.
I wouldn't go there.

Pony up a couple hundred dollars more, and you can get something decent.

Check to make sure the can you choose is rated for supersonic ammo with a short barrel.
Subsonic ammo is VERY disappointing when it comes to terminal performance.
