looking for specs on carrier groups,Why cant find?
 

There seams to be tons of info on the receiver parts upper & lower but non on the specs for the rest of the gun.
Is this info Taboo?

No, you can describe it or ask for the info... What specific specifications are you trying to understand?

Sent a pm to you...I would like to find out which carrier I have.
Thanks

No offence but this belongs on the forum and not PM...

You asked about the specs of the AR-15 SP-1 carrier and if it were possible to convert a non-SP1 carrier to SP1 specs... I used to have the exact specs for the Sp-1 carrier on my website (www.Quarterbore.com but it seems I can't find it now. I can measure one of mine when I get a chance...

For what it is worth, I understand that current DPMS carries may well be SP-1 spec and they may work fine with a lightning link. I have not ordered one or used one myself but I have seen were people have said that they work...

As for the Bushmaster or just about any other AR-15 carrier, yes, you can modify it to sp1 spec... Here is a pic that shows a Bushmaster AR-15 Carrier (top), Colt SP-1 Carrier (middle) and Colt M-16 carrier (bottom).

It's just a matter of getting the trip area milled square and to the right size. You could modify an AR-15 or M-16 carrier but obviously it would be easier to do an AR-15.

Here is a guy that can do one for you assuming you have a legal LL...

Thanks for the picts.
Why is it ,that there is no where with blue prints for the rest of the gun? :confused:

I don't know... what parts are you after? I sell blueprints for the AR-15 and M-16 lower receiver and those are the single most critical part (with exception of the Bolt Carrier and barrel extension) plus my AR-15 Resource CD has other drawings and dimensions...

You can buy all three here:

No, it's not the dimensions of every piece but why would you want that unless you had a manufacturing company and wanted to clone the parts... and even then, it would be easier and cheaper to use the manufactures of the parts in the first place....

I understand what you are saying. I just thought it was odd that both the upper and lower blueprints were readily available for download in a bunch of places, and that every place I saw did not have the small components of the gun(with dimensions). Even on sites that specialize in milling & making their own firarms.
It was just a questions really, I mean its a heck of alot easier to spend -$100 on a lower, than to machine one yourself. I guess some things are just "the way they are".
Any how ,thanks for your input,I like the site...

I'm intrested as well, to the specs on a sp1 carrier to. When you get a chance can you post them??

Thanks
