    I am building my 1st m4 and I'm confused about the buffers. I chose to go the "mil spec" route. I've been looking at buffers now and some are $199 and others are $59. Is there a difference between buffers?; performance wise. Or am I just paying for the name brand?

    Good choice going w/ mil-spec.

    Depending on your AR or more specific it's gas port diam. the required weight will very. The weight will alter the cyclic rate bolt bounce and felt recoil. There is a sweet spot as well as to heavy or to light. Go to heavy and you'll run into feeding issues.

    Most common would be a H buffer. I personally use a couple Spikes T's, an H2, and a A5 standard weight buffer.

    Spikes is making a T3 now which I'd like to try.

    If you're spending more than $40ish on a buffer something is wrong.

    Thanks for your help. So, for the $40 are you talking a out the whole kit, or just the buffer itself? I haven't seen many kits for under $40. I saw a BCM Buffer kit (H) for $55. I think the H2 was $10 more. Would you recommend that?

    Your OP had no mention of a buffer "kit". Are you talking buffer extension, spring, castle nut, end plate, and buffer? If so you will of course be spending more money. Check out Ammunition, Magazines, Rifle Parts, Bulk Ammo and Rifle Accessories – Palmetto State Armory or AIM Surplus Home for complete kits. BCM is a good choice as well. Personally I'd find the most reasonably priced mil-spec kit from the place w/ the lowest shipping costs.

    So, the difference between the BCM and the one through brownell is most likely the name on the buffer kit? I just don't see the price difference of $100 for the exact same amount of pieces.

    By kit are you talking the buffer, spring and receiver extension? I'd choose the BCM over whatever Brownell's sells, it could be a commercial diameter RE and who knows what brand it is. With BCM you know what you're getting so it's worth an extra $10-15. You get a lot for the money with BCM so why not pay a few bucks more and be sure? Still, the alternatives MJ linked are a great deal.

    As far as which weight to go with - standard, H, H2, H3 or Spikes - first, what gas length and barrel length are you talking?

    I am going with a 14.5" barrel. So would you recommend H, H2, H3...?

    Carbine. And it's going to be an m4. I'm not sure the carrier

    That's helps out a lot. Thanks!!!! So now that brings up another question. Which buffer weight should I go with? Just a standard? I'm building a .223

    so i must confess. i paid 140 for my buffer and spring. however im so happy i did. my friend bought one and i shot it his rifle with it in.. theni went and bought one. heres the site Heavy Buffers | Products
    its a custom tungsten buffer. i have one fo rmy a2 stock. it completely eliminated both mine and my friends boing noise. and the cycle is very crisp. it made the bang a touch louder but reduced recoil. my advice is buy one. you will be amazed. my friend and i both own stags. mine is a standard 20' his is a carbine. just my 2 cents
