| Who here rounds the front of their standard BCG bolt teeth?To help the bolt slide smoother into the barrel extension. |

I am convinced that the dremel company is a front company for the brady bunch. They have destroyed more firearms than all the gun grabbers combined. |
| I get a kick out of some (experts) on here.If you are able to purchase parts and assemble them into a rifle then you must be a master gunsmith.Someone ,at some point designs parts and usually improves upon the design.These ''quacks'' that put thought into the design and opperation of the rifle,rather than the assembly have never accomplished anything.The LMT MRP bolt with rounded teeth was designed by a guy who must have been(crazy)to think of altering the standard bolt.I have made improvements to alot of my rifles that would seem crazy to some of you but are the norm to an armorer or gunsmith.If my 12 years of gunsmithing diden't give me the ability to improve on designs I would consider myself a total dumby.I lose respect for ar15.com when I hear responses like some of you give.Do you actually believe every part you purchase is impossible to improve and the gun is giong to blow up in your face if you try?Use common sense,and if you are not a gunsmith keep your expert knowledge to yourself so us bigboys can talk. |

You first, chief. Video it, please, and have someone else standing by. Not to save you when your face blows off, but to laugh hysterically at you when your bolt undergoes catastrophic failure, and to post the video for the rest of us to laugh at. Did you drill holes in your gas tube to soften the recoil, maybe? Let me guess, you shave off two of those three pesky lugs on a 1911's barrel because "they're not needed", right? Maybe make a notch in the last one, so it'll "lock up faster"? Square the ejection port as well, I'm guessing? What are your gunsmith credentials, by the way? Just out of idle curiosity... |

I know its really weird, seeing how I did not make this super tacticool modification to my RRA carbines, that my bolt slides into the barrel extension smooth as silk every time.
I can now see the error of my ways and will remove material off those bolt lugs, making them shorter and weaker, to allow them to move even more silky smooth as them slide home. Okay. Sarcasm off now. I cannot feel my bolt lugs touch the barrel extension. The first sign of contact is the key contacting the inside of the receiver. This mod cannot possibly make something better that is already perfect. |

Quoted: I totally agree, but he wasn't getting any help from POF and was at wits end. He took a leap, machined the ramps, and now his guns work flawlessly.Quoted: Quoted: I get a kick out of some (experts) on here.If you are able to purchase parts and assemble them into a rifle then you must be a master gunsmith.Someone ,at some point designs parts and usually improves upon the design.These ''quacks'' that put thought into the design and opperation of the rifle,rather than the assembly have never accomplished anything.The LMT MRP bolt with rounded teeth was designed by a guy who must have been(crazy)to think of altering the standard bolt.I have made improvements to alot of my rifles that would seem crazy to some of you but are the norm to an armorer or gunsmith.If my 12 years of gunsmithing diden't give me the ability to improve on designs I would consider myself a total dumby.I lose respect for ar15.com when I hear responses like some of you give.Do you actually believe every part you purchase is impossible to improve and the gun is giong to blow up in your face if you try?Use common sense,and if you are not a gunsmith keep your expert knowledge to yourself so us bigboys can talk.

I myself think it's a mag issue, but on my gun, I can see where the bullet tips are hitting, right under the existing feed ramps. He just machined down to that point and problem was eliminated. Now he can use ANY mags.

Yeah, but the radiused leading edges are a mixture of 1) a solution in search of a problem, and 2) something nobody ought to be doing to their own bolts unless they have the ability to re-heat-treat their bolts. |

I'm not agreeing with him. I would never do that myself to my equipment. I was just showing LMT's enhanced bolt |

Quoted: For all the people giving this guy a hard time......ever seen the new modified KAC bolt? Just saying........ Yep. And the LMT. This guy ain't KAC or LMT. Just saying....... If he's serious, he should check out http://www.ar15.com/forums/forum.html?b=6&f=49 and not GD. I mean, we have had guys come in here after fluting their barrel with a dremel. |

Quoted: Yeah, but the radiused leading edges are a mixture of 1) a solution in search of a problem, and 2) something nobody ought to be doing to their own bolts unless they have the ability to re-heat-treat their bolts. Machining on your bolt shouldn't necessitate any reheat treating. |

If you were simply polishing them, I imagine they'd be fine, but aggressively removing material *could* expose softer core metal. YMMV, IANAL, etc. |
