Heavy Buffers

[Scotd]

Has anyone used a Heavy Buffer in their M & P 10? I am changing my M & P 10 to a A2 Buffer Tube and was not sure about using the stock carbine buffer and tube with the spacer.

I contacted Clint at HeavyBuffers.com and asked what he recommend for the M & P 10. I told him that I thought the Bolt Carrier was proprietary.

This is the response I got.
I recommend an AR10R-XH buffer and an AR10 buffer spring. More info here: Heavy Buffers | Products

I also have rifle buffer tubes here: Heavy Buffers | Springs & Tubes

Everything is in stock and you can order directly from my website. If you prefer to use PayPal (+3.5%) send me a list of the items you want and I'll send you an invoice.

Let me know if you have any questions.

Thanks,

I just happen to have a heavy "H" buffer in mine at the moment. It runs fine. But then it ran fine with the stock buffer also. If yours is reliable I'm not sure I'd mess with it.

I run an H buffer and it seems to work well. In my case though I had horrible fail to feed problems from day one and the H buffer at least partially helped to make things reliable. My M&P10 has finally moved up from being a bolt action to semi auto.

I'd agree though that if things are already reliable, I don't see a need to change it unless you really want to.

I have Clint's buffers for both 223 and 308. I have run into problems with both using 55gr. 223 and 147gr. 308's. They short stroke with the lighter bullets. They work fine for 77gr. 223 or 160+ 308... I put the stock buffers back in them and have the heavies in a drawer.
I may bring them back out again when I develop heavy loads for my rat guns. These were Direct Impingement guns. I'll test them in my POF gas guns in the near future..

I used the HeavyBuffers product on my 9mm top for my small frame AR. I found the part to be terrifically reliable and super quality ,if expensive.
I plan on buying his build-your-own part numbers with the several ounces of tungsten weights for my kit. That way I will be able to develop my own recipe & have enough weight to make another & maybe two. Again, expensive, but the alternative is to buy ?? different buffers to get to the right combination.
I've put Wolff XP springs in my kit, for starters anyhow, and have found that having a Spikes T2 around for experimenting (along with some home whittled styrene spacers & regular ole' quarters -yeah, pocket change-) so that I can mix and match to get the proper buffer combinations as needed.
