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 !
AKA FMJ

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?
bump... because there is a shit load of good information in here that could save people a lot of time.
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.
