[ARCHIVED THREAD] - Is this a Complete Colt SP1 upper?

Posted: 2/22/2006 4:21:03 PM EDT

Just traded for the following. I'm not an AR-guy at all as you can tell.

Are these all the parts to be considered a Complete Upper?

Yeah -- with one catch. It's a large pivot upper. If you have a mil-spec small pivot lower, you'll need an adapter pin to mate them together. No big deal, as they aren't expensive.

Thanks M4Madness.

I was hoping all was well so I don't blow myself up when slapping it on my RRA lower (which it does fit BTW).

Then it's an M16A1 upper instead of an SP1 upper. Any photos of the other side?

So it's not an SP1 upper?

Correction: I just realized that it's supposed to be a COLT M16A1 upper, not an SP1.

Thanks.

I thought that front hole looked to be the same as the rear. Did you get it from CDNN? I saw a while back they had some brand new condition M16 A1 uppers, they were cheap too, but I noticed they were advertising them as SP1 uppers.
