    I have a standard 16" barrel Stag Arms carbine. All original Stag parts built by Stag.

    It seems to have a lot of gas. Over the years I've added a Stag FA bolt carrier group and H2 buffer. It still seems to have harsher cycling than it should, even shooting .223 Remington ammo rather than 5.56 NATO.

    My PSA mid length carbines are very nice and mild in comparison.

    Any thoughts?

    If your Stag is a carbine-length gas system, then it's probably over-gassed a bit, most carbine-length systems are; it's a bit harder on the bcg , but for most people it's not enough for it to really matter in terms of wear....

    Heavier buffers aren't always the panacea that the interwebs make then out to be...

    Just because the heavier buffer might mitigate some of the recoil impluse moreso than a standard weight buffer doesn't mean the gun will be softer shooting! All that kinetic energy and mass pushed to the rear when the bolt cycles to the rear has to be released on the forward stroke! A heavier buffer coupled with a heavier FA bolt generates more momemtum on its return journey and you can actually get some bolt bounce if its too much... Something to think about.

    I have several rifles that do better with standard carbine buffers in this regard.

    My Stag behaves the same way, so does my Colt. They feel rough and harsh. Now my midlength Spikes is pure pleasure to shoot.

    Now you know why a lot of guys prefer a mid length gas with a 14"- 16" barrel.

    I think thats the nature of the beast. I had a stag years ago and it was pretty harsh
    for a 5.56. But super reliable.
    At first thought it had no recoil for a rifle and it was my first AR-15.
    Would have never known the difference if I hadnt shot mid-lengths.

    The Stag was my first. I have a midlength PSA too and it is great. The difference is amazing.

    Why not tone it down some with an adjustable gas block?

    Mine does too.

    But then I love the smell of my own gas.

    An adjustable gas block isn’t an option since the gas block is a part of the front sight. I can try a carbine buffer. New or extra power buffer spring? Any other suggestions?

    Pull the sight tower off and measure the port to find out if it's too large. If found to be excessive I guess you could try one of those restricter plugs that KAK or someone came out with about a year or so ago and go from there.

    Buffer and/or buffer spring? Worn or weak to begin with? Why do you assume it's too much gas pressure, rather than too little resistance to the gas pressure? Either would give you similar symptoms.
