    Because a lot of PSA barrels are FN made. And nothing on the FNH-USA site about their AR barrels specifically.

    That is because FN doesn't make any commercially available AR's or AR barrels (with their name on it).

    If you contact FN to make a barrel for you, you MUST submit a drawing for the barrel (to include the GP size). So the GP size could be anything.

    Fair enough answer.

    Yes, our hammer forged barrels are made by FN.

The barrels are Hammer Forged, individually MPI and individually High Pressure Tested. We are one of the few companies to offer this superior barrel.



    Does this mean that FN is making your barrels???

    Would it be safe to assume that a gas port is within normal tolerances if a weapon functions normally? I suppose i could remove the rail and the gas block to plug gauge the gas port... I dont see why any reasonable person would do such a thing unless there were function problems pointing to a too big/small GP.

    40 rounds without a a malfunction does not give much of a sampling of a weapon's reliability.

    IG is asking for a very detailed point of information for a reason. Many entry level AR's run a more wide open gas port to make up short comings somewhere else in the gun. They become over-gassed so they will run with garbage ammo, quality stuff, and everything in between. PSA is still cutting their teeth in the AR market and building a name, so gathering some info of the ins/outs of their guns is the best way to judge their quality in the long run.

    Is it over thought inconsequential minutiae...Sure, but this is the internetz, it's what we do.

    My apologies IG. I read your post quoted on another post here and misinterpreted your question.

    In response to your question, I have not asked PSA folks what size their gas ports are manufactured to. I give it a go. If i can get a response from them I will post it here and plug my own PSA barrel to see if what they say is accurate.

    No , as far as long term reliability 40 rounds is nothing. But I have not alluded to any durability determinations and wont for a good while.

    Duly noted. Thanks for clearing that up. I misinterpreted I.G's question, a perfectly logical and valid question at that.

    As far as overgassed... the PSA rifle I have does not seem to have as much recoil as my duty M-4, this alone may not prove that the gas ports are not oversized it does point in that direction. When i get a bit of time and motivation i will remove the necessary components and check the gas port.

    It is why I lurk this forum. Lots of good info to be gleaned. Here is an interesting thread on various FN manufactured barrels and the results from tests
