r/300BLK

Is 6 inches really enough?

Hey all! Looking to suppress my steyr Aug in 300 blackout. Barrel is 16 inches, 1/8 twist rate.

The Omega 300, Hexion 300, and Nomad L are the suppressors I’ve been looking at the most, but want some informed opinions on the matter. The CGS Hyperion has also been of interest, however I feel the price tag is substantially higher for no real benefits over the others.

Ive also looked at the Hexion 762 and standard Nomad as form the few videos I’ve seen, the noise difference is virtually unnoticeable on a semi auto rifle as port pop is the primary noise, so having the shorter suppressor is a plus.

Steyr does recommend against flow through designs because a potential lack of back pressure to cycle the pretty hefty bolt, however I’ve been able to reliably cycle subsonic rounds unsuppressed already, so I feel any back pressure is going to suffice, even that of a flow through.

My use case is fairly niche and modularity isn’t a high priority. The only other real use I might have is swapping it onto the 5.56 barrel for the Aug as well. I don’t intend to suppress my .308 G3 clone for the time being. Regardless, I believe all the options I have listed have back plates that can be swapped out for Keymo or ARS style devices.

Anyway, just looking to get some knowledge and opinions from those who have actually used suppressors before.

Thanks!

Today put on the Dead Air Nomad 30 can and a reclaimed Primary Arms Prism scope from another project until I figure out what to run. Also 10rd mag for when I can line up from the bench.
Still unfired at this point.

I’m about to start testing some subsonic hunting rounds (Maker Rex 200gn Expanding Copper Solids) for whitetail deer this November.

Even with the right ammo for subsonic hunting, this is going to be used at a maximum range of 50 yards. I know that Maker makes excellent bullets, but I’ll still be testing these loads through a chrono and on gel blocks before taking them into the field in November.

I’ll be referencing several of my reload manuals (Hornady, Lyman, etc.) to figure out a starting load and tune from there. I’d love to hear any recommendations or results anyone feels like sharing.

Test rifle will be a frankenrifle with a 10.5” PSA upper 1:7 twist, running an Omega 36M with a 30 cal end cap.

Bought one of these a few months ago full price and they are running a deal for $100 cheaper. Great starter suppressor for .300 blkout. Works on 5.56 as well 😉. @blackstoneshootingsports

Side note: they are running a new daily deal and this is day 2 of 7. Make sure to peep what they got going on (I’d advise signing up for their emails anyways as they are another great retailer in general)

Full parts list to follow

Also the Holosun is just a placeholder. I already had it and just threw it on to have something on there. So I’m open to optic recommendations and anything else

Can someone help break down this build?

Got this ammo from someone for free and I have no idea what it is

Just came in today. Super excited. 8” 300 blk.
Added dead air Xeono A1.
Hopefully get time to try it out this weekend.

This is my first 300 BLK rifle I have ever built so I’m pretty happy how it turned out ran supers and subs 100% all day. last round bolt open on every mag still getting it through its break in cycle but I couldn’t be more happy, let me know about the ejection pattern cause I’m not sure on that yet still new at this.😁
