would the fact that the fire control group pocket wasn't modified to accept a sear change anything? since it couldn't accept a sear, was it considered a machine gun? Quote HistoryQuoted:

Fail to see why welded holes have any Bering what so ever. It is not usable in that way any longer. Current configuration is No Holes. Inside appears to be untouched by mill work. If it is not in the NFA then what is the issue ? The act of drilling sear holes is manufacturing a machine gun. Under the ATF's "once a machine gun, always a machine gun" rule, welding up the holes does not convert the machine gun back to a semi-auto. So if the gun was not registered under the NFA back when the holes were drilled, then it is an illegal machine gun despite the holes being welded up. would the fact that the fire control group pocket wasn't modified to accept a sear change anything? since it couldn't accept a sear, was it considered a machine gun? Yes, it is still a machine gun. There are commercial legal semi AR lowers that are already milled out, and may be lawfully sold, because they have never been drilled for the autosear pin hole. ATF has ruled that the single act of drilling the hole for the autosear pin is the act which creates a machine gun. |

It doesn't have to be the exact size and location ... but the Colt sear-block holes are much larger, with a center significantly off where an autosear pin hole goes ... and finally, the Colt blocks are only pinned on one side, not through both sides. So there is no issue with the Colt. FWIW, I wish I had seen those photos while the auction was still on-going, because the seller is local to me. I would have loved to swing by and taken a close look at the inside of the receiver walls. If the marks were both inside and outside, it would confirm that it had been drilled, then welded up.

There are at least three different iterations of the Colt sear blocks, at least two of which are drilled with blind holes through both sides of the receiver - but oversized and off center. i have removed examples of all three types over the years. |

How did they install it w/ blind holes on both sides? Drill through the receiver wall and a bit down into the block itself, the press in the blind pin. Repeat on the other side. Pretty much like you install any blind pin. |

Ah, I misunderstood. Through holes on both sides of the receiver, blind holes in the sear block itself. Aren't the holes in the receiver lined up with each other?

Avoiding some perceived legal issue from the ATF? Appeasement? just colt going above and beyond to protect citizens. On SP1s and Sporters things like larger pivot pin holes, lack of sear relief on the uppers. Later changes included the sear blocks w/ bolt carriers without tails to work with said carriers and larger fire control pin holes. I think it finally dawned on them that it didn't make financial sense and made everything milspec. |

They also brought us oversized FCG pins and semicircle bolt carriers. No other manufacturer did this crap. They've only very recently stopped doing it. |
