| Hi all, I have a new, unfired, CMMG 14.5 bbl. I did not have an H buffer installed. Would it be a good idea if I pick up an H buffer for this rifle, or will the standard buffer be OK? |
If you're asking this question, is it fair to assume that you have not fired this particular carbine yet? We can not advise with any certainty via the Internet that your set up will or will not work. If you shoot with the standard buffer & it works fine then I see no reason to switch buffers at that point. Give it a range test with the supplied buffer first & see how the rifle functions. I wouldn't get to bent about it now but it never hurts to have different buffer weights on hand during the carbine's first range trip just in case you do run into function issues. This way you do not have to wait another week while you order & wait for the postal carrier or Mr. Brown to arrive with a new one. |
| You are correct, I haven't fired it yet. I was just concerned a little after reading the thread about the full auto malfunction. Thanks for the advice... Would be a good idea to have a different buffer on hand anyway just in case the standard doesn't work well with my rifle. |

The first buffer used by the OP in that thread is made for the Cav arms polymer lower with an Oly 45 ACP upper on it. It is quite a bit heavier than a 9mm buffer(9mm buffers are about the same weight as an A1/A2 rifle buffer). I use a 9mm buffers in my 16" carbine and I have had no issue at all. Many people use 9mm buffers in their carbines. You can use any buffer from a standard to a 9mm in what ever barrel length/gas system you have, and as long as everything was put together right and doesn't break, you should never have an auto fire incident. Though other failures(short stroke, FTE, FTF, ect.) can occur depending on many other things. Most of the people in that thread are arguing about a completely different incident. There's almost no mentions about what may have actually caused the "auto" fires. I have no idea if it could be caused by using a slightly longer half pound buffer. Though I'm sure it did cause the short strokes. |
