Now what do you do with that big ugly hole in the side of your receiver?
|
|
I believe the picture is kind of deceiving. The pin is still in there. |
|
|
What hole? RIF! Added a pic for clarity |
|
|
Looks good but does the cut pin tend to fall out or is it secure? |

That pin is in very very tight and is never gonna fall out. If you pull it, it raises the metal at the edge of the hole badly. I had one removed by KKF years ago and it looked bad. It's best to leave the stub of the pin in IMO. |

Good job! The sear block is one of my (many) complaints with Colt. I find it interesting that the LE only Colt's are blocked. Guess this just keeps cops from committing NFA felonies.

Nice work! I have done two so far. I might finally do my last two.
|
|
other than just being remnant of a bygone era, & ugly, what advantages is there in removing the block ?? i only have one shooter with the block, the other shooters (9 of them) are unblocked.

Boomer, I've never seen one with two pins on one side and one on the other, if you're not counting the vertical roll pin. The two types I have seen and have in my possession are one with only one small pin in the right side, and one with two larger pins, one in each side. Both types have the vertical roll pins. Anyone have a picture of the variation with two pins in one side? Lonny |

Any chance on fixin the pics at the beginning? I was just directed here for a similar problem but can't really see the "fix".
Thanks! Jeff Z |

Doesn'tthat take away from resale value? Just curious before I do it?

Thanks, Boomer. I've never seen that one before. MIGHT be rare. Maybe it ought to be left alone. By the way, I was NOT doubting you, just anxious to add to my meager knowledge. Lonny |

Thanks for this thread.
I safely removed sear blocks from a Sporter Lightweight and a Govt. Carbine. |

I took my 3 pin (double blind pin and single roll pin) block out last night. I had to grind it out with a drill and an abrasive disk. I went down the center of the block, away from the receiver walls, until I reached the hollow between the two blind pins. I then used a punch to get the pins moving laterally. Once I got one pin out, I pounded the other one straight out using the hole from the first pin. You do have to grind close to the receiver walls in order to loosen the pins enough to remove them as they are press fit extremely tight. I was left with two pins that can be dremeled and JBwelded into the hole should I choose. I may just leave the holes open as sign of my disdain for Colt's appeasement.

I encountered pins that have a tapered end. That makes them look HUGE from the out side.It also makes them look like they are one pin going straight through. But they are NOT pressed into the lower, just the block. The hard part was trying to pull out the roll pin and keep the wheel away from stuff I didnt want marked up!
Great thread! Took a hour from start to put away |

Once paid $125 to have one of those two pin blocks removed. Just got a one pin lower receiver last week, and thanks to RamblinWreck's insperational thread had a go at it with a dremel. Followed the instructions to a tee, save two changes. Rather then using those little cutting disks that come apart, used one of those large reinforced disks. The cutting disk did not bust, and did not have to cut a chunk out of the top part to gain clearance. So was able to remove the block in one piece, with one cut, and one cutting wheel. Also, did not have luck with pulling the block out with channel lock pliers. Before starting the dremeling had already stripped the lower so I simply knocked it out with a punch and hammer thru the receiver extention ring. The roll pin did not crack in half, but was bent. Hit the roll pin with a punch and it snapped off right at the base of the receiver, nice and clean.

Anyone have pics of a receiver with the two large pins, I think that's what I have?
On this type of pin, can the block still be removed as described in this thread? |
|
Colt will now redo your preban sear blocked Colt lowers in the current Colt black for $200. There is a catch though. You are SOL if the sear block has been removed.
|
|
What do you mean by "redo"??? Refinish? Remanufacture? Replace? |
|
|
He is talking about the Colt's Custom shop refinish service. Being in a ban state that could be an important thing to know if you want an old receiver to match a new upper. Guess you could remove the block after the refinish, or better yet paint it black with Norrell's.
Interesting note here, sounds like Colt's can remove and install these blocks, how else could they anodize the lower? |
|
I did mine (2 pin version) and both pins fell out. Now I have a hole on the left and right side of the selector. Oh well, the block needed to come out. It was interfering with the function of my 9mm upper. |
