We will have available a small number of 5.56mm Advanced Combat Bolts shortly. The cost is 120.00. If you are interested, email your request to [email protected]
  Also available are our new cam pins. The cost of these is 9.00 dollars. Here is one shown next to a standard one.

Looks like an LMT bolt with lower fit and finish quality.

what advantages does your new cam pin provide over the std. ones?

Same question here. The bolt does look like the LMT, excepte parked, (which isn't a downgrade, IMO), which has been hit and miss in performance, based on which setup you choose and which ammo you shoot. |

Less mass, same strength. Indexed because one of the sides is reduced slightly which results in less friction within the upper and better unlocking. It does not allow the cam pin to rotate and bind the firing pin. It will be used in all weapons we produce from here out, and on request on conversions. |

I agree that there are superficial similarities to the LMT bolt but there are also significant and distinct differences that offer genuine dynamic improvements. Things to note are the full set of 7 lugs with stress relieving cuts, the fully supported bolt face and lack of undercuts beneath the lugs either side of the extractor pocket; the twin springs (captured by the extractor) and recess for the extractor buffer for our LMG; heavy radiusing and stainless steel construction.
This was pulled out of a weapon after proof firing and extensive testing and has not been cleaned. The ACB retrofits into ANY weapon. |

For $120 I can have two brand new Bushmaster or RRA bolts. Will the ACB outlast two bolts from these manufacturers? What will it do in terms of performance that these bolts will not do?

Stainless steel? If I may ask, what series is this? Isn't carbon steel more wear resistant? These do look nice....kinda want one just for the sake of diversity.
Thanks! |

Firstly, the bolt performs in the same way as every other bolt; it seals the breach and in that respect, it does nothing differently or better than anything else on the market. However.....where this bolt comes into its own is the performance, reliability and longevity that it provides. Let's get something straight here. If you are an average civilian shooter, then don't buy this bolt! Spend the money on some really good ammo because you are going to notice and see the difference much more there. This bolt is overkill for such a user and not recommended. If however, you shoot many thousands of rounds and are concerned about longer term performance, extraction reliability and bolt breakage around the extractor cut, then you should seriously look at this when considering high performance bolts. Dynamically, this bolt is substantially stronger in key critical areas than ANYTHING else currently offered. We have run 10's of thousands of rounds with them in both direct impingement and gas piston weapons and have found them to be unstoppable. A control bolt made from this material has been fired with proof loads 168 times so far with no movement, distortion or fatigue and we believe this offers significant performance improvements. Of course, we are not the only ones and the design and product is being reviewed by the government. At the end of the day, pay your money and take your choice; we have a limited amount available which we are releasing at this time, if you want one, buy one, if you don't then don't. We're just interested in offering the best products possible and will continue in that endeavor. Thanks for the question. |

Not in this application. This is a steel that was developed for use in gears and transmissions, primarily in the mining industries and performs well under sudden and repeated loadings and stresses. It's a 3300 series, specifically 3310. |

Will this bolt work with all ammo, and all upper lengths?
LMT claims their bolt is designed for use with 62g M855 and 14.5" uppers. I have not had an LMT one that worked properly, but I would like the dirt resistance of the bolt you have pictured for my M16. |

Will the extractor still work with one broken spring and one intact spring?
Or does it require both springs intact to run? Thinking about failure rates.... -z |

That's a very good question! IIRC, the LMT Enhanced bolt wouldn't run with only one spring. If that's also the case with the LW bolt then I don't see how using the dual springs makes much difference from the standard single spring extractor. |

How regularly do you need the springs replaces if at all? How easy is it to find replacement springs? What wear is evidenced on the extractor over time? |

The bolt will extract with one or both springs. With one spring, extraction is still acceptable. |

All bolts, barrels and barrel extensions are Mag Particle Inspected after proof firing. We MPI in-house with our own Magnaflux equipment. |

We have not yet had to replace springs. Replacement springs are available from us or you can cut down (and grind the end of) AR selector springs in an emergency situation. We have seen no wear on the extractor itself, we use the standard material to make this part rather than stainless and have not yet seen a reason to change. It also keeps the cost down, you would not believe how much those extractors cost in terms of machining time. |

My 6.8 has broken a bolt. It sheared the lugs on both sides of the extractor. This design looks like it would help. Do you plan on making a 6.8 SPC version?

Posted: 7/14/2005 12:58:57 PM EDT

Yes, it is under development. We have some military 6.8SPC bolts in the same stainless steel currently in inventory. These are "standard configuration" bolts but use the better material and are identical to those issued to U.S. combat units. |

In this picture I notice that in between the two srpings is a depression in the middle. One thing I wish the LMT had was the ability to use a standard extractor spring in case the two improved extractor springs failed. Now you can always carry spares but I have a billion standard extractor springs and one set of improved. It would be nice to be "backwards compatible" Do you have any plans on making the improved bolt backwards compatible with standard extractor springs? |

Um...you noticed that. This bolt was also designed to work with current inventory and be fully compatable with all platforms. The danger of anything proprietary is that in a crunch situation, the lack of back-up parts could pose serious problems. When we designed this bolt we were looking at a multi-faceted role, direct impingement, gas piston, light machine gun etc, so we incorporated everything into the bolt that made it perform better and then added some redundant features that would keep the weapon running no matter what. The depression you mention was designed to accept an extractor buffer that reduces extractor bounce in the LMG sustained fire role. It also happens that you can put a standard extractor spring there which will work (not recommended for general use) in an emergency. Features like this are incorporated into IP claims. The same is true of our piston system; drive out the gas tube pin and reinsert the tube, change the carrier and you're back to direct impingement. |
