| Just picked up a NIB LE6920. My question is about the bolt. It has no markings at all? No "C" No "MPC"? and no blob of paint either. Just wondering if anyone else has a non marked Colt bolt? My SN# is 287XX. My last 6920 was MPC marked and had a glob of grey paint on it. Just curious. |

Is yours made in USA, or Canada? what about the other aspects: is it an M16 shrouded carrier, markings under HGs, forge marks, stock (as compared to that shown in Skintop's 6520 thread), box it came in, etc.? before reading your follow up post, I was going to sugggest a closer look at the bolt, as they are sometimes very faintly marked. oh, and aren't pix mandatory around here?  congratulations on your new rifle, regalgseguy! |
No, it is actually widely used these days. BATF ruled the use is in, and of itself not an effort to convert. Colt LE rifles have shipped with them since around March 2005. I offer the letter that addresses it. The language is on page 2. Sorry I don't have a larger version or .pdf:   Many AR users have enjoyed the benefits of this interpretation |

USGI bolts are required to be proofed and marked MP once they have passed. Commercial bolts are not. Since 2001 we have seen quite a few commerical bolts simply marked C. Never heard of one marked MC though. I propose that MC is short for MegaCycle: dictionary.reference.com/search?q=megacycle The pic is of a letter to Colt's lawyer, it is not a Ruling. The only Ruling the ATF has put out in regards to M16 parts is Ruling 81-4 that states a drop in auto sear is a machine gun. |
| OK, I got an idea and used my scanner to scan the bolt at high resolution. What it revealed is a bolt that was very poorly stamped "MP" Looks like it's a bolt that was destin for an M16/M4???? I bought the rifle from a Police Officer in MI. He got it on the letterhead of his deparment. The rifle is unfired. |

This is one of those situations that would be very hard or ATFE to undo. There are too many rifles out there with the shrouded, full-circle bolt carrier. . . . At worst, the ruling would be prospective. |

My 6920, which I bought new in 2002, had the Sporter unshrouded and half circle carrier in it. Everytime I shot it, the firing pin retaining pin would get bent and beat all to hell. I finally got tired of prying it out everytime I field stripped the weapon so I decided I would replace the carrier with the LE version (which it should have had in the first place) but changed my mind when I saw how much it was going to cost to buy a new carrier, pin and retainer. Instead, I called Colt up earlier this year and spoke to someone in customer service about it. He took my Department address and said they would send me a new firing pin, retainer and carrier. I asked what carrier it would be and he said "the M16 carrier." I said OK and in about 6 weeks or so I finally had all the parts. Works like a dream now and no more mangled retainer. Apparently Colt finds no problem with putting M16 carriers in semi-autos and, of course, neither do I. Its what should have been in it from the start. |
| Guntoter, you have had better luck with Colt than I. I contacted Bill Chartier, who I was told was the Colt service representative for LE rifles. He told me the carriers were not “defective”, but that there had been a bad batch of FP retaining pins. He sent me several retaining pins and asked that I try them. |
