Sorry for the confusion I may have caused. The exact story is that I bought a colt barrel off of someone for a close to nothing price. This barrel came off of a Colt HBAR Sporter. For some strange reason, he already parted out the barrel nut, barrel extension, delta rings, springs, etc. The gas port has been drilled and the front sight assembly is already on.
I thought at the time, oh well, I'll just go out and purchase all those parts and put them back on. When I goto the extension, I said, ok, now what.
I have done business with GPSS in the past for a lower parts kit, so I called Tommy Haskins for a quote to install the parts. So I will be sending this out to him and I'll post pictures of the finished products.
Thanks again everyone. Maybe if I had more experence, I might have tried to pin it myself, but for 30 or so bucks, why not have him do it and head space it too. Now if he calls back and says it's going to cost more for additional work, this barrel will be going on the EE fast.
