Ice Arms 6.75″ 300 Blackout Barrel: First Shots

| March 26, 2014 | 5 Comments

I had the opportunity to shoot my .300 Blackout pistol yesterday.

There are a lot of experimental factors going on in this build:

  • My first .300 Blackout build
  • My first handloads for .300 Blackout — complete with problematic M80 military surplus pulls
  • Ice Arms has a bad reputation, and someone registered on the forum just to spread the word about their past poor performance in the 5.56 barrel market and customer service
  • I had to sight in a new optic

I went through my test “ladders” of handloads (I’ll cover that in a different post) and used them to sight in my Primary Arms optic.

The indoor range had a 45′ line. 15 yards is close distance for us in rifle class, but this outing was mostly a function check. According to the things posted about Ice Arms, most barrels were so out of spec that there were problems chambering rounds, and accuracy wasn’t even “minute of paper.”

I am happy to report that the Ice Arms barrel, my 300 build, and my handloads all functioned without a hitch.



The groups are:

  • Around the left 10
  • Three around the right 10
  • Two under the X (I flinched on the third shot and it was a winger. I know.)


The real test will be during our first rifle class, where I’ll be shooting at 25, 40, and 100 yards. I’ll also put between 300 and 400 rounds downrange depending on class size.

Stay tuned, but so far there are at least 3 builds with Ice Arms barrels in the SBS pack and they’re all working 100%.

    Finally got a good test done with my ICE ARMS barrel as well. My Stainless Steel 7.5″ performed very well with 110gr hand-loads. My accuracy at 75′ was around 3-4″ groups lightly supported on a sandbag. I think it’s capable of even better accuracy. So far I’m pleased with ICE ARMS. I did notice that this batch of barrels is visually different then the previous, maybe they have corrected their issues.

    I recently put a 10.5″ 223 Ice Arms bbl on my 556 pistol build (swapped out a 7.5″ bbl). I have done a small amount of testing with it, but not really yet for accuracy. I’ll let you know how it does this weekend if we get some decent weather.

      Good luck! Does your barrel look similar to mine? It appears that a lot of the 5.56 barrels people had trouble with look radically different, including the profile, coating/finish, roll mark, etc.

    I know you planned on running supersonic in the 300. I was curious if you have tested it with subs to see if it will cycle with out a suppressor?

      Hi there! We can’t own suppressors here, so this build is supers only. It may be possible to shoot both via an adjustable gas block.
