    Wow. I was under the impression that hammer-forged barrels in general were not very accurate.

    The HK PSG-1 has a hammer forged barrel with polygonal twist and is considered by many to be one of the most accurate semi auto rifles in the world.

    Colt Canada, FN, Hk, KAC (for some) and several others do CHF barrels.

    They are superior serivce rifle and MG barrels. In my experiences they are not as accurate over distance as SS barrels can be.



    The PSG-1 is accurate - but I would suggest nothing a Mk11 or custom barrelled AR10 could not do, and Hk would not charge $8,500 to rebarrel it for your unit...

    Yes I've found that out too. I've fired 2 different PSG-1s a few hundred rounds through both out to 500 meters in the late 80's at Quantico (that 6x scope leaves a lot to be desired). The PSG-1 is a very dated design now. I agree that the .308 AR platform is just as accurate if not more accurate for a whole lot less money. I too find SS barrels more accurate than most other barrels but have roughly 1/2 the serviceable life as other barrels.

    True true -- I was just hassling you - and still bitter over Hk's rebarrel fees from years gone by.

    I am going to have to agree with KCS on this one. I just received my rifle I ordered in February. Notwithstanding the long wait, they also shipped me the wrong gun. It was quite frustrating to say the least.

    They could sell so many more rifles if they just got their act together.

    So what exactly IS the advantage of a CHF bbl???
    Also, are you guys saying that Colt Canada (Diemaco) does offer CHF, but COLT USA does not?? (IOW's, the Colt 6920's, etc, sold here in the US do not have CHF, but Canadian/Diemaco bbls do??)
    What is the advantage to CHF bbls???

    Finally, what about BCM bbls? I assume they do NOT have CH Forging??

    More hammer forged barrels are produced in the workd than by any other method. Virtually all pistol barrels are hammer forged. Why? While initial equipment/mandrel/hammer cost is very very high, it is so fast and QC is so easy that in mass production, per unit costs are much much lower than any other manufacturing method.

    Besides cost, the hammer-forging process work-hardens the inside barrel creating a harder and tougher barrel without making it much more brittle. A big plus indeed. hammer forging also changes the crystalline structure of entire barrel, making to tougher.

    The downside is that, compared to button or cut barrels, induced manufacturing stresses are horrendous, and must be relieved, usually by heat, and sometimes with cryo. failure to properly stress-relieve will hurt accuracy. Always. Most production rifles do not have fully stress-relieved barrels, just partial, to save cost. That's why your Remington barrel "walks" shots as it warms up.

    Another downside of hammer forging is that the high equipment costs mean that you are stuck with what the product that the manufacturer is geared up to make, whereas a button or cut-rifling maker can switch tooling easily to make custom barrels easily.

    If you own a rifle by Colt, Remington, Winchester, Ruger, Marlin, Sako, Savage, almost any European brand, or a pistol of any brand, you own a hammer-forge barrel. It probably is working fine for you.

    FN makes AR-15s?

    Last I checked AR15/AR-15 was a Colt patented name thing.

    I know FN makes M16A2s, M16A3s and M16A4s as well as most of the belt feds used by the US Military.........and I have a few friends employed by FNH.
