Hello all,
Have a RRA 9mm build that has run literally 100% - absolutely no problems at all with promag or cproducts 9mm mags. One thing I have noticed is that its is much more difficult to charge than my 5.56 AR. I dont know if that is common to the design or not. My main concern is that I see a lot of postings about 9mm buffers. My 9mm carbine (16" M4 type) has a standard "H" buffer, I believe (came with the RRA collapseable stock). Is the 9mm buffer necessary? Does it aid in longevity or just in reliability? Since my carbine has been 100% reliable, I wont worry about the upgrade if it just aids in reliability. |
Thanks for the replies all! I dont know if I would know what excessive wear and tear would look like on my lower  . What signs should I be looking for? So far everything looks good but I probably only have 800-1000 rounds through it. The only thing that I dont love about the 9mm is that, like I mentioned before, it is harder to charge than my midlength. It has not given me a single feed/extract problem whatsoever though.
I am pretty certain that it does not have the 9mm buffer. The 6 position stock was originally purchased seperately so it has the standard "H" buffer I believe. Just wanted to make sure that the 9mm buffer isnt "necessary" and that Im not damaging anything as I put more and more rounds through the gun. From the responses, it sounds like I'm good to go. |

+1!! Unless you are seeing signs of excessive wear and tear on your rifle (at least on your lower receiver), I wouldn't mess with a good thing. +1 My 9mm has been 100% so far even with the standard carbine buffer (not 9mm weight) and I'm not planning on changing a thing unless/until it has problems. |

The stock buffer RRA puts in their 9mm carbines IS a "9mm buffer." I don't have the actual weight handy, but it's heavier than a regular CAR buffer. And as badazar says, if it's running 100%, don't mess with your gun! +1 Don't fix it if it ain't broke. GH here is your weights. BUFFER WEIGHT (oz) 5.56mm Rifle (std) 5.2 5.56mm Carbine (std) 3.0 5.56mm "H" Carbine 3.8 5.56mm "H2" Carbine 4.6 5.56mm "H3" Carbine 5.4 9mm (std) 5.5 9mm "A" 6.3 9mm "B" 7.1 9mm "X" 7.9 |
