5.45x39 SBR questions

[Arik]

If I remember correctly true 5.45 barrels under 16 inches have a different twist rate

When is the last time you bought a 5.45 barrel, let alone bolt from them?

I say give them a ring and see... gotta feeling they're making them in batches now, remember seeing them on the site last November. Another maker is Adams Arms...

They do but it doesn't matter.

Ah that's right they have a piston!

I have a 5.45-10.5" Ballastic Advantage barrel on an ar pistol. It shots the 7N6 well. It will destroy a golf ball at 50-75 yards, the bullet exits side ways. Not exactly a scientific test. I have never tried grouping it but with a red dot it will hit what I aim at. With a few exceptions the shorter the barrel the more accurate because the barrel will be stiffer.

It's the weirdest round, it will start to tumble right away even after hitting a thin sheet of plywood but if you shoot a dense object like a tree trunk- it will just ice pick straight through.

Definitely an interesting round. Fun to shoot. Still cheap to stock up on.

Wanted to do a 5.45 AR build but since 7N6 isn’t being imported loss interest

I’ve been shooting 7n6 out of an AR upper for years, a fun round with interesting ballistics but when it got banned I tried a few commercial loads and my 1/9 barrel did not group well with any of them. Fortunately I have a large stockpile of 7n6 but when it’s gone I’ll stick to 7.62x39 & 6.5 Grendel.
5.45x39 AR parts have really dried up, not gone but outside of AK74s there’s not much demand for it. And ballistically I think 6.5 g beats the pants off it, and 12” 6.5g barrels are plentiful.
