looking for specs on carrier groups,Why cant find?

[hambone2]

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?

[Quarterbore]

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

[hambone2]

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

[Quarterbore]

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?

[Quarterbore]

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....

[hambone2]

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...

Thanks
