What is the gas port size?
Shawn H on May 22, 2018
Can I swap this out of a 300 blackout and use the gun as a 5.56 nato?
Erik W on Sep 26, 2018
BEST ANSWER: Yes, but. I just swapped out 5.56 for .300. I learned that while the 10.5" 5.56 was carbine gas tube, the 10.5" .300 is pistol. This is due to the .300 powder charges and required pressure for cycling.

If you are swapping to 5.56 you will need a new gas tube, and possibly a new gas block, depending on what you currently have.

From carbine to pistol length gas system I needed new gas tube, gas block, and foregrips (free float since I could not longer use front sight post).

Amazing barrel for the Price
I purchased this barrel some time ago and have been using this on my 300bo pistol since. I was absolutely astonished at the accuracy of the build when it was completed. I've had zero issues no matter the bullet weight or brand of boxed ammo. I'm getting 1/2'' groups consistently with my hand loads (17.5gr h110 and 125 gr hornady sst). This has become my go-to gun and I couldn't be happier with this purchase.

Good barrel for the money.
For the money, it's a good deal, especially if you are running a can, or nothing but supersonic ammo. I couldn't get the new 10.5" 300blk build (PSA barrel, standard buffer, Wilson Combat gas block correctly installed, FailZero BCG. Most of the parts were swappable with another 300blk that would run everything flawlessly, and no change) would not run 220gr Remington subsonics without a can. Ran 150gr Aguila abour 80% of the time. Runs 100% with 110gr Lehigh Defense. With a red dot and 110gr Controlled Chaos, it's a 2MOA pistol, so not too shabby. Just wish for a slightly larger gas port.

Excellent Barrel For the Price
PSA's 10.5" barrel in 300BO steel/nitrate finish is very impressive for the price. I didn't expect much from this based on the price however I've been quite impressed. Quality of construction is surprisingly pristine and accuracy is to match. Can not notice any difference between this PSA made barrel and the Wilson Combat barrel regarding accuracy. Do yourself a favor and buy yourself one(or 2)as soon as you see them available. They don't stay in stock very long. Very Impressed.
