| Just got a Colt 9mm and changed out the stock for a Vltor and was wondering if I need to use the old buffer from the Colt, or can I use a heavy buffer that came with the Vltor from bravocompanyusa.com? How about the spring? |

BAD INFO..... If using the std "rifle" stock assembly, use the STD std rifle buffer as is. DO NOT go mixing "CAR" parts into a rifle tube, forget something, and accident waiting to happen. I have a 2nd rifle buffer that was weighted for the M11 slowfire I have, but the rate of fire was similar to m16 in 9mm, so that bufer (7.04oz) went to my multi purpose swap top multi caliber SBR

| Wait a minute. I know the spacer is for using a 9mm buffer in a fixed full length stock. I did neglect to mention that you would also need to use a carbine length spring as well. This is info is directly from RRA's web site. I recall reading this when I was researching 9mm ARs and I just went back and verified what I recalled. I was correct. |

The 9mm buffer is a "CAR" part.... CAR-  Rifle parts -  Here again, I'm not a fan of mixing parts. Use the parts as intended. This whole "9mm" buffer thing is way out of hand.... It is common name for a "CAR" style buffer that weighs 5.6oz,, barely anything more than the std rifle' buffer weight of 5.2oz. So why would I need a "9mm" buffer in my rifle tube? Maybe if running full auto with a CAR stock to control rate of fire so as to help control the possibility of "bolt bounce". I would do it with a semi-auto and CAR stock just to simulate the weight of the rifle buffer in smaller package.... I prefer the A2 stock myself, fits me better, and the 7oz buffer helps with the suppressor by delaying the bolt open slightly to allow more gas to go out the front. |
| SBR_711, I am fully aware of the differences between carbine and rifle buffer set-ups. Are you stating the information that Rock River Arms has on their site regarding the use of 9mm buffers with A1/A2/fixed stocks is incorrect? I also understand that the standard rifle buffer is just .4 oz. lighter than a 9mm buffer so the rifle buffer would probably be fine with a 9mm AR. |
