Shoot it...it will most likely loosen up

I'm experiencing the same thing right now on a Colt build. Different pins work slightly better but its still real tight. Shoot it a couple hundred rounds see if it loosens up. -W
ETA: I see you are unable to get the rear pin in, and can't shoot it. Something is out of spec there. Can you check with a known good sized upper or lower? That would be my suggestion. -W |

I can try and measure inside diameter of the holes if a good upper.

I had really tight pin holes in a lower I was assembling(the pins measured spot on). I used a drill bit, the shank end, that was just undersized and wrapped it with some 1000 grit paper so it was a tight fit and hand polished the holes. Worked out very well for me.

Did you polish the holes on the upper or lower.?

I was thinking about some polishing, but I don't really have the tools. I don't want to alter the .250 take down pin holes on a $400.00 Colt lower. I'd sure like to make these titanium take down and pivot pins work as well or better than the standard Colt parkerized ones. They are lighter, stronger, match the stainless pins that come with a Colt match trigger group pins and match the stainless trigger guard pin. They just don't fit the receivers well. I'm going to shoot a couple hundred rounds through mine, even if I have to use a punch to get it apart to clean it. I'm hoping it will loosen up just a little. -W
ETA: While I was happy to find SOMETHING that matched the other swirl polished stainless pins, I am more concerned with function than appearance. If these pins don't loosen up in one range trip, they are out of here. -W |

I'd just clamp them together in my vise and run a .2505 reamer through the hole, but I understand that not everyone has a large machine vise and box full of precision reamers, so if I am to help you, I need to better understand your capabilities. What sort of equipment and skills do you possess?

Six,
$400.00 was a bargain! Skills? I have some skills brother. Do I need to say it? I do have a valid CA Engineering license. Does that work for you? -W
ETA: I'm also a CA licensed C-36 Plumbing Contractor, B-1 General Contractor, C-16 Fire Protection Contractor, Certified Brazier, Certified Med-Gas installer, and Certified Plumbing Inspector. Do you want some more credentials? -W |

When I began the assembly I could not get the pins in the lower unless I would have used a hammer to press them in. Also, whatever you do leave them on the tight press fit side. They will work themselves in over time. |

I'm pretty handy . I have access to numbered drills. Drill press. Have not gone too far outside of ar platform as far as gunsmithing goes. Have completed a handful of other ar builds just didn't want to force the rear pin in until I asked first. It would definitely need to be taken out with a punch if I can get it in. All I have done so far is to take the coating off of the holes in the upper with a brass bore cleaning brush.

Nearly 1,200 posts here and you haven't figured out that if the first part of a post doesn't contain a quote or ^^^^^^^ before the response, then it's directed at the OP? If I was asking about your skills, I would have started that post with a quote from your post, or said "Wools10-" |

All I have done so far is to take the coating off of the holes in the upper with a brass bore cleaning brush. Doing it with twist drills and a drill press is a little sketchy, probably leave an ugly hole at best. I'd suggest a hand reamer: http://www.ebay.com/itm/1-4-HSS-Straight-Flute-Hand-Expansion-Reamers-/261296870996?pt=LH_DefaultDomain_0&hash=item3cd681d654 You will need a tap wrench to drive it if you do not have one already. |

We cant all be professionals like you Before you try to insult someone by alluding that they do not actually possess the skills they claim to, you should be certain that they really don't possess those skills. I have no idea why your are so defensive; even if I had asked you, it's not like I was insulting about it. It was a very simple and straight forward question. Are you feeling inadequate in some regard? That's really the only explanation that makes sense (and no, that question is not phallic in nature) |

You all can get fucked. I have 30 years experience building ar-15's every model you could name, I wont help another person. Get fucked im gone. - Oh, whatever will arfcom do without members who have shitty attitudes, derail threads and contribute absolutely no useful information for the OP? (And if you really have 3 decades "building" ARs, that makes you at least 45-50 years old. I'd say you're a little immature.) BTW, I have actually built an AR. And I don't mean assembled from finished or nearly finished parts. |

What makes it a hand expansion reamer? Or is that just a term of making a hole larger manually? Also what is the threaded portion of the reamer a the front ? |

Expansion reamers can be expanded and resharpened as they wear. This is not the same as adjustable reamers, which can be increased and decreased in size. The threads would be to expand it before resharpening. A solid reamer would work fine for your purposes, too, but that expansion reamer is a great price, and the pilot will help you get it started straight. Real easy to get caddy wampus with a reamer that has no pilot if you do not have the equipment to align it properly before entering the hole. |

Big fucking deal so does blackthorn and Vulcan jackass. LMAO Actually, they source a lot of their parts. I'm talking about actually machining everything from solid stock. ETA: You're the new NOVESKE LMMFAO Never claimed to be, don't aspire to be. Building the same thing over and over bores me. That's why I bounce between guns, miniature engines, RC car parts, etc., when I'm not busy doing paying machine jobs or running my primary business. |

That ugly, heavy piece of shit would feel like a boat anchor in 3-gun or carbine courses, and I seriously doubt you could keep up with a 33 year old in excellent physical shape with 20/12 vision in such challenges. It also wouldn't hold a candle to my 22" Wilson bull barrel rifle shooting tailored 75 gr match hand loads at 600. I like your 50 mile qualifier, too. None of my rifles are even legal in your commie state. If you're ever here, though, I'll take that challenge. I'll even handicap myself by running a .308 AR. |

It looks small in his hands. LMMFAO I thought you could shoot something "YOU BUILT" Dude, youre a joke. -W out.
