Looking for a 16" lightweight m4 7 or 8 twist 5.56 at barrel. Prefer mid length gas port.

Also interested in the same type barrel in 300 blackout.

Anyone have one or know where they're in stock?

Thanks,
Bb

After looking through my stash i did find one. Its a 16" hbar 5.56, 1_9 cm. The barrel has been chambered and crowned. But no gas port drilled and Its missing the pin to the extension. Although it did have fluting in both the front and back portion of the barrel.

Let me know if your interested.

Thanks but I'm looking for a little faster twist that's ready to go.

I have a 20 inch colt hbar 7 twist.
