I have a new AA 16" mid-length rifle and am currently running a Spikes ST-T2 buffer.  The rifle exhibits all of the classic symptoms of being over-gassed.  I have a 9mm buffer without a home and was wondering if there was any reason I should not try it in my Grendel.  Thanks.

From what I have read, try the H3 buffer or switch to a rifle buffer. Also, an adjustable gas block might help as well.

I am well aware of those options.  The question is, can I use the 9mm buffer I already have.



AA recommends against a 9mm buffer in their FAQ, but I can't see a reason why when so many others have run a 9mm buffer in their AR variants over the years.

No deadblow effect as with a conventional buffer. Not recommended for Grendel.

9mm Buffer for Grendel ?

Deadblow effect is BS.

I wouldn't use a 9mm buffer.

I went with a H3 buffer.  It's all good.

I'm running an "H3" (actually ST-T3) buffer in mine, but I also have an adjustable gas block so I can fine tune the gas system to whatever I decide to run.

I have a Vltor A5 on my Grendel, works great with the rifle buffer (5.2oz)  A H3 buffer should work the same (5.6oz).  The ST-T2 is only 4.3oz.  

If you want more weight I think Clint can build up to 11oz buffer weights.

According to Spikes, it doesn't even weigh that much.

Use whatever you choose.  Not all 9mm buffers are created equal.

If its over gassed doesn't it make more sense to do something to adjust the gas? You could also use the MGI adjustable gas tube if you want to keep your original gas block.
