    If you are not rearranging protons and neutrons into different elements, you are not changing the density of the steel. Hammer forging it not rearranging protons and neutrons. It is hardening the steel and changing the grain structure/alignment.

    Heat treat that results in phase changes, like quenching steel, can change the density.

    First use was making MG-42 barrels MG-42 were rated at 1200 RPM. It was noted by the Germans that the barrels lasted longer. Not to mention they could make them faster. Than with traditional method's at the time. The MG3 is still made with a CHF barrel, The M-240 has a CHF , The M-249 has a CHF barrel , The AK has a CHF barrel alot of modern military fire arms use CHF barrels.
    Ok, this I knew, I was just hoping I wasnt out of line posting that.

    No not out of line perfectly reasonable question IMHO.

    I was just trying to explain the variety of different military weapons that use the CHF barrel manufacturing method.

    All of which have high volume in a short time frame in mind.

    Colt Canada (then Diemaco) has used CHF barrels in their C7 (M16) and C8 (M4 like) systems for over 20 years.
    20,000 rds life span has been achieved on barrels that where shot at a low to moderate rate of fire.

    Hk, FN, and many other companies have used CHF barrels in rifles, as well as wait for it, most pistol barrels.

    You need to make the determination for yourself, OP.

    It sounds to me like a cold hammer forged barrel will not make any difference to you other than lightening your wallet a bit more.

    Well in all honesty I want to know that I'm putting good money into a quality weapon. If that means spending an extra $100 to do it right, then I'll spend it. The whole reason why I was asking if it was worth it is because I know there are a lot more people on here that are more knowledgeable on the subject. Unfortunately since I don't have tons of money right now, this is going to be my only AR for a while (trust me the BRD hit me a long time ago when I got my first setup together). From the different arguments being made, it definitely seems like CHF is going to be the way to go. It's the direction I've been wanting to go in since I've been shopping for a new upper but I figured if I could go non-CHF and put that $100 towards an optic or ammo, I would. Lots of great info here and I feel a lot more educated thanks to you guys. Thanks!

    For who? The military? Possibly - they have a mission requirement that CHF can help meet.

    I think this is wise, in your case.
