Great and solid build. However the adjustment screw for the gas block was missing. PA was amazing in getting on this and got in contact with Odin and we got it resolved.

Make sure your hand guard is big enough…


The barrel is fantastic (deserves 6 stars), but the gas block is gigantic and won’t fit under a lot of the modern slim rails. In particular, it rubs on the inside of a Geissele Mk16.

Great barrel, but the gas block is gigantic

The gas block that cones with this barrel is gigantic, and wouldn't fit under my Geissele handguard. Once I replaced that, everything was fine.
<br>At 100 yards, this barrel will easily put 3 out of 5 rounds through one ragged hole, and the other 2 won't be too far away.
<br>Note: this barrel will NOT be compatible with the traditional combination front sight / gas block. The standard gas block is made so that there's a .025" gap between the shoulder and the gas block for the handguard cap. This barrel has the gas port drilled .025" closer to the shoulder, so that the gas block will be installed flush to the shoulder, and thus can only be used with a free-float tube.
