A heavier buffer increases lock time and reduces bolt bounce. For a 16" barrel with a carbine length gas system with no suppressor, I'd use an H or H1 buffer instead of an H2 buffer.
The barrel is not chrome lined but is QPQ treated. If you're concerned about mag dumps and durability, then QPQ treated barrels are probably a better choice for you than chrome lined. |

Any buffer you recommend for an h1 and why not an h2 |

Any buffer you recommend for an h1 and why not an h2 An H or H1 buffer from Colt, BCM, or PSA should be ok. The H2 was introduced to eliminate issues the 14.5" M4A1s had with bolt bounce when firing full auto. Your mag dumps out of a 16" AR are not going to come anywhere close to the rate of fire a full auto M4 has. An H or H1 buffer will provide the benefit that you're looking for with a heavier buffer. If you're dead set on getting an H2 buffer, Aero Precision sells a very reasonably priced H2 buffer. http://www.avantlink.com/click.php?tt=cl&pw=55963&ctc=j06yi4id0m00zk8a02gtd&mi=13601&url=https%3A%2F%2Faeroprecisionusa.com%2Far15-h2-buffer.html |

No, because Spikes ST-T1 and ST-T2 buffers weigh less than the H1 and H2 weights.

The Spike's units are not "buffers" in the traditional sense, they do not have the series of sliding weights so do not "buffer".
"H" and "H1" are the same thing in buffer weights. Nothing wrong with an H2 or even H3 if he wants to spend the money. No a heavy buffer does not correct the timing problem, but it helps to mask some of the symptoms. |

We don't know if there is even a timing problem. From the information the OP has provided, this seems to be more of a theoretical question since we don't know if the OP is having bolt bounce, early unlocking, or any other issues. |

I don't know since I haven't fired it yet. Any tips on how to identify these said issues? I understand that budget rifles such as mp sport two have standard internal parts that you can easily upgrade I'm just wondering what you can improve? Also would a full auto bcg be beneficial? |

1. On my mp sport 2 the buffer doesn't show if it's an h2. I understand it's a carbine gas system and it's more harsh on the internal parts but I've heard you can eliminate the problem by getting a heavier buffer? If this were true which buffer would you get? 2nd. What's the barrel on the mp sport two? It's not chrome lined that I know of. Is it still good for mag dumps and durability? Assuming your ejection pattern looks like mine below I'd probably go H/H1. The review may also answer a few other questions you have about your rifle....

I often wonder why people worry about things that dont matter because they saw it somewhere. The M&P is great as is for the pricepoint. It was my first rifle and has my highest round count, approaching 4K now, no problems whatsoever. If there is a problem, it will go back under warranty but I do not anticipate ever having to do so, Bottom line, get out and shoot that rifle, find out what you like and dont like, then built the rifle you want. Leave the Sport alone, no sense having a box of unused parts laying around. |

Fired it yesterday. Thanks everyone. It was fun ejection pattern was fair. (3 o clock if not a little higher). I just wish I had a different buffer to help with the recoil a little

The M&P sport 2 will make you a fine rifle. I would go h buffer if you want to try to soften it a bit, as well as swap out the flash hider for a brake like a vg6 gamma if you want to mag dump it. Mag dumps are a waste of ammo IMO but to each their own. The Sport 2 also only has a 4140 chromoly barrel vs the 4150 on the original. It would service you fine, just might not get the life or accuracy out of it if your dumping mags.

Get out and shoot that rifle before you try and guess or ask about upgrades. Its kinda like putting the cart before the horse and there is no reason to have a box of parts laying around that have no use. Spend some money on ammo before any accessories. |
