Does anyone have a video or shooting session written review of the steyr 300blk barrel with subs and a common non-flow through can like a sandman s or surefire socom? Wanted to get feedback on reliability and only see heresy reviews on YouTube so far and just marketing video from steyr when they released since they  are still quite new.

If people have feedback on which is better (Heresy vs Steyr) is appreciate some feedback too

I've been waiting on the Steyr & didn't even know they were available yet.

I'll order one.

I have the standard non nato version. Do the 42 round waffle mags work with the 300 blkout rounds?

I’d like to convert mine to 300 but I’m not down to buy new magazines all over again.

I have heard mixed reviews about the 42 round 5.56 mags from Steyr when loading them with 300blk. I bought the barrel and I mounted the cherry bomb and hoping to shoot it next weekend.

I just ordered the .300 BLK barrel.

What suppressor are people recommending?

From what I could gather I think they recommended something with higher back pressure so no flow throughs. Hoping that it would work well with a Sandman S or SureFire SOCOM, but I don’t own a 300blk aug yet.

I emailed Brian at Steyr, he says they have been using the AAC SDN-6, the AlleyCat 762, and the new B&T.

I’ll have to talk to SilencerShop when I’m ready to plunk some $$ down.

That’s a super random list. Literally none of those are particularly popular cans from my understanding lol. Did he say anything about some of the more common usa offerings?

I listed the 3 cans he mentioned.

Still no range report on one of these? I'm amazed!

Been super surprised too.

Here was one, but no suppressor info unfortunately:

My barrel was delivered today, but unfortunately, I’m out of town on business

Finally returned from my business trip, here are a few pics of the Steyr .300 BLK AUG barrel.

The notch in the forward grip to accommodate the larger gas block is interesting.
Gas block has 6 positions.

Muzzle device is an A2 style.

USA made as per markings.

Steyr recommends a ‘non flow through’ suppressor, which I presume to be a higher back pressure can.

I will be shopping for a suppressor soon…

Very interested in the performance between the two barrel and any validation the waffle mags work

Went and shot the .300 BLK barrel in my AUG today.

Not really a ‘range report’, per se, and by no means scientific,  just wanted to have a little plinking play, and mess around with the gas port settings a little. At this time, I didn’t care much about accuracy, as I was at an indoor range, and only shooting 25yds max.

I fired about 60 rounds.
40 147gr S&B SuperSonics. Cycled perfectly with them, using gas block setting #2 (standard setting ) mostly. Also ran setting #1 (low gas setting), the rifle cycled perfectly as well.

I also fired about 20 rounds of Ammo Inc 220gr subsonic. Unsuppressed (since I don’t yet have a suppressor for this gun).

The ‘LV’ setting is supposed to be for subsonic suppressed, but I used it to see if it would cycle this ammo without a can. I found that 8/10 rounds fully cycled and loaded the next round in the mag. 2 didn’t not.

Next 10 rounds of subsonic were fired with gas block in the #2 setting. 10/10 cycling.

When I got home, I found that I could not rotate the gas plug to remove it. It was pretty stuck.
A pair of needle nose pliers and a tap with a plastic mallet loosened it up and I removed the piston and spring.
Pretty dirty from just 60 rounds, especially compared to my 5.56 barrels piston after a 2-300 round session.

Tossed them in the ultrasonic cleaner and they look good as new.

I look forward to getting a suppressor,  and a real range testing trip to see what it can do.

On a side note, I used regular PMags (my AUG is a NATO model), and as expected, they functioned flawlessly with the .300BLK rounds. I’m going to have to mark them as dedicated .300 mags, so I don’t fuck up and confuse them with my 5.56 mags.

now’s a great time to get a can! My last two took 4 days and 2 days to be approved
