I have a 1980's series large pivot pin Colt Sporter H-BAR. I need to get an upper with a flat top so that I can use a telescopic sight. Any recomendations on a company that would make a nice accurate flat top large pivot pin upper with a M4 type profile and Chrome lined barrel and chamber? If I cannot find an upper I am just going to sell the thing and buy a gun I can put a telescope on!

You can buy an adapter pin that will allow the Colt large pin lower to accept any small pin upper receiver. FWIW, if you sell the Colt (which I wouldn't) and it's a verified pre-ban rifle, it is worth more money in many states that have kept the AWB laws in place. NY comes to mind. There are others.

I guess that would work. It would probably be cheaper to buy an upper anyway than an entire rifle.

how well do those adapter pins work? Do they affect accuracy in any way?

The pin simply replaces the large Colt takedown pin with a new pin that will allow the lower to accept a small pin upper. Here's a bit more info from a couple of websites. http://www.pkfirearms.com/store/get_items.aspx?type=0&term=12The replacement pin is listed under "Offset Screw & Nut - Colt Style" and it's $5. Next from mapartsinc. website: http://www.mapartsinc.com/anything.asp"Skip this next paragraph if you don't have a Colt lower receiver... Sometimes, when Colt has a bad day, they manufacture what is politely called a "large pin lower". Most would call it a reject. They come from a hole drilling placement error, so they just center it up in the right place and drill it out bigger. Instead of a proper .250" diameter hole (as our uppers have), you get a front pivot pin hole in the lower that is .312" diameter. Simple solution? Get the $5 Colt Offset Pin. It will adapt any standard USGI dimensioned upper to any Colt "large pivot pin" lower."

That is the stupidest statement I've ever heard coming from a business. And of course they also tell you they use only the best quality parts... M&A who needs them?

I will not buy anything from maparts either. The info was just for the pin related info, nothing more. BTW, I'd keep my large pin pre-ban Colt before I'd take their advice on an AR.

All you need is an offset screw. Midway usa has them under: DPMS Offset Screw and Nut AR-15 Matte Adapts upper receivers with .250" takedown pin holes to fit old Colt lower receivers with 5/16 (.312)" front pivot hole diameter. http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=316328But you can also go to DPMS and get it for $3 plus shipping. I just got mine yesterday and it cost me a total of $4.3 with shipping. Hope this helps
When Ronald Reagan was president, we had Bob Hope and Johnny Cash. Now that Barack Obama is president, we have NO hope and NO cash.

I like the looks of the Noveske rifle, but they also said they would build me an upper on a danials large hole upper receiver, they said this was the way to go.
