    like you I used regular buffer for years
    I cant tell any difference with my H buffer

    After YEARS of HEARING about the 9mm buffer
    I bought one
    RRA SECOND type 9mm buffer 25bucks

    Slap it in my 14.5 Defender 2000 M4

    The Barrel DOESNT JUMP OFF MY RANGE BAG LIKE IT USE TO

    Compared to me Back Up Bushmaster/LMT 14.5 with H buffer

    I CAN TELL A HUGE DIFFERENCE!!!
    Its TRUE its does work nice!

    My Brass also shoots out the same distance as it did with the regular buffer
    runs good great ZERO Hic Ups


    I use to Laugh about puting 9mm buffers in a M4/carbeaner
    Mr Wilson was RIGHT !

    When I finally picked up a new Upper and lower it came with a H buffer. To be honest. After a few hundred rds... I can not tell any difference. and because I switched from a 16" HBAR to a 14.5" M4 profile.. The muzzle jump and recoil feel a little more severe due to the loss of the extra barrel weight I'm sure.

    So, I can't say as I'm sold on the heavier buffers for the 16" and 14.5" carbines. I know the shorter SBRS seem to run better with them. Just my take on it.


    I USE TO BE LIKE YOU AS WELL

    Bought a 9mm buffer and found out myself cost 25 bucks

    I could tell a BIG Difference NOT LITTLE

So if you start to get any kind of timing problems, this might be the cause (just an FYI).




    C4

    My RRA 2nd model that I order from RRA YEARS AGO
    has no screw hole at the end like the First model


    Also has some type of INSERTS that rattle back and forth


    I called RRA they Told me the 9mm buffer with the screw hole is theBetter buffer of the 2

    dont really know why theres 2 models maybe you can Find out

    OK, maybe someone with more experience with buffers can correct me if I am wrong. Is this the correct way to determine which weight buffer to use (for reliability)?

    Pick the lowest power ammo you want to use.

    Put in the heaviest buffer you have.

    Load one round into a magazine and make ready.

    Fire the rifle holding it very loosely.

    If the bolt fails to lock back on the empty mag you should move down to the next lighter buffer and repeat the above test.

    Is this right?

    Yes, great thread. I looked around for a better spring, and came up with Tubb's SSS flat spring. For $25, is it a winner?

    I have always used that test. If the weapon will fire 5 single rounds, locking the bolt open on each shot, I do the same test with the weapon rotated 90 degrees until it's been in all positions (6, 3, 12, 9 o'clock). If it passes all that, I call it good to go.

    Interestingly, my MRP 16" (mid-length gas system) will pass this test every time with a Colt 9mm buffer and an ISMI recoil spring, using 5.56 pressure ammo. I know the prevailing wisdom is that this is too much weight for a middy, but it's still slightly less weight and more gas pressure than a 20" with rifle buffer.
