Buffer Type?

[Shihan]

Im sure this has been asked to death but what ype of buffer should be used with a 16" carbine?
Also what type comes standard from the factory with a
M&P15T
LMT lower ?


Thanks

With your set up I'd use an H buffer.

S&Ws come with a CAR buffer from the factory.

The H will help slow it down and stop any extraction issues. I'd also be sure it had a black extractor buffer and I'd use a Crane 0-ring or MGI D-fender extractor enhancer over the extractor spring.

Use the buffer that comes with the gun, up until such point that the gun does not run. Then consider respringing/buffering.

Often the one that comes with the gun when new is the best one to start out with.

As time goes on, you may experience some gas port erosion, which would cause the gas port to enlarge, thereby altering the balance between the gas metering and the moving masses(which includes the buffer). This changes the cycling behavior.

You can help to restore the balance after that occurs by using a heavier buffer.
The buffer should allow good function of the weapon with a variety of ammunition, and in a variety of operating temperatures.

Too heavy buffers can cause short-stroking, and too light buffers can cause overcycling. Strive for a good balance.

Im making a parts order for a customer this week so I figured I would pick up some stuff for myself while I was at it and had no idea what type to order for myself. Life was easy when I would just have the armorer do anything that was needed.

So to verify from the factory

S&W M&PT uses a standard Car buffer?

LMT uses a H-Buffer?

Thanks

My LMT lower came with a standard carbine buffer in it.

I called LMT and they said the H-buffer would work better and then I called Stag and they said the standard buffer would work better unless I was using the weapon on full auto.
Is there any down side to using a H-buffer?

If using very weak ammo it might not lock the bolt back.

How about a buffer recommendation for an 11.5"?
