What would be the most reliable bolt/carrier for a 16" carbine with an A2 stock? I'm thinking the LMT Enhanced would be the way to go (even though it's expensive), but would there be any issues with the rifle stock/buffer assembly?
EDIT: I'm looking at semi-auto only. |

If you're looking at semi auto only, I would stick with the standard LMT BCG or look at the Denny's Super Duty. I've heard here several reports of issues with the enhanced BCG. What issues have you heard of with the enhanced BGC? I'm not really impressed by the 5k-10k service live of standard bolts, so I'm looking for something better. |

There are a lot of variables concerning bolt life. There's alway the possibility that a Colt bolt could break at 2k rounds & a DMPS bolt could last for 10k so there's not really a whole lot you can do to predict when one will fail unless you just don't shoot a lot. Just buy a known quality bolt from a reputable manufacturer & have fun shooting. Keep a spare for each rifle as well. |

The most important feature I look for in a good reliable BCG are properly staked gas keys and a good brand name manufacturer which have a very low defects and problems.
Brands like BCM, LMT (not with MIM gas keys), S&W, Sabre Defence, Armalite, etc, have properly staked gas keys and are good brands. The longest BCG I had used was on my first Colt AR-15 SP1 which I used for about 13K+ rounds without any problems. I also agree to keep a spare bolt just in case because it's impossible to predict any troubles, maybe a complete BCG so if there's any problems just switch BCG and keep on shooting. If you want to try different than standard BCG take a look at LWRC ACB, KAC E3 and Young Mfg. |

My search foo is weak until I renew my membership. Below is a link to a recent thread about the top bolts I still think the LMT Enhanced Bolt is a great idea that may not be executed very well. I have read several threads where people have gone back to their original bolts due to odd happenings. This is one of those threads that includes opposing arguements from some of the most experienced and best contributors to this forum. PursuitSS, Molon and DevL. I think you'll get the jist. Heavy Duty Bolt thread. |

So it sounds like the best way to go would be to simply buy a standard, brand name bolt (BCM, LMT, etc.) along with another spare standard, brand name bolt. Thanks everyone. My only suggestion is that you look for an MP inspected bolt. HPT and Shot peened if possible. Nice Mad Cat by the way. |

Can you tell me what "MP inspected", "HPT", and "Shot peened" mean? |

MP or MPI = Magnetic Particle Inspection. It detects imperfections in the metal that might lead to premature failure.
HPT = High Pressure Testing. I'm not a metalurgist, but I've been told this is a stress test to weed out imperfection visual MPI might have missed. Some metal gurus don't like this process claiming it shortens the life of the metal. Shot-peening is a process of hardening the surface of the bolt to make it more resistant to wear. Legend has it several companies do these tests and simply don't advertise it. Don't believe it. If it doesn't say it, they didn't do it. If they did do it and just don't say it, don't buy from them becasue they're boobs. Chances are any BCG you buy is going to be good. Those tests increase your chances for pennies extra. |
