| OK, I did a search in this section before posting this. What is the difference between the two. I guess most people who have a Colt AR are mostly who it applies to. Are most receivers (other than Colt) one or the other? |
| From what I've seen and read there is no difference or benefit to having larger pins for the FCG. I know Colt and possibly a few other use larger pins. The reason behind that was when other companies started to produce AR's colt went on their lawsuit spree so other manufacturers had to change things like the buffer tube and various other components so their AR's would be "different" than Colts. But that's what I've been told so I might be wrong. |

Quoted:
Colt used the larger .170 pins to discourage the installation of a full auto hammer, trigger, and disconnector. Everyone else is building the mil spec size of .155. Most of the major aftermarket trigger manufacturers offer the .170 Colt size for replacements. What he said. Colt is the ONLY one who ever used the large dia. pins. And then only from about 1991-ish to just two or three years ago. Colt AR15s from 1964 until just prior to the 1994 ban used the smaller, standard diameter pins. They switched to the larger size during their Sporter Match model line and kept it thru the Match Target line. But as I said earlier I believe they have switched back to the smaller, standard size again. So if it ain't a Colt receiver then it has the smaller, standard sized pins and holes. If it's a Colt it could have the larger size depending upon it's vintage. |

my Colt le6921 has the .170 hammer/trigger holes. does this mean I cannot upgrade the trigger/hammer to a nice 2 stage or whatever???
actually, I have a registered lightning link that I want to use in it, and have a modified 3 round burst trigger kit that makes the rLL work in select fire mode. Can I just not use this? |

Can I just not use this? I'd set up both the aftermarket trigger and the lightening link on a separate host gun. Leave the Colt un-molested. |

But the burst trigger kit won't work in your Colt receiver. |
