Hi, I was hoping that I could get some help on an illustration. I'm having a tough time finding images of an AR stripped barrel without the barrel extension installed. Does it thread onto the barrel extension? What does a Barrel Indexing Pin look like? I also need a picture of an Ejector Does anyone have their AR in pieces that they wouldn't mind taking a few snap shots to help me out. I'd really appreciate the help. This is what I've been working on. http://img.photobucket.com/albums/0903/24601/4d2443cb.jpg I'd appreciate any suggestions and/or help. |
Terrific Image. Can you share a higher resolution version of this? |
| Yes. The bbl screws into the bbl extension and there is a little hole in it. You drill threw this same hole and just a bit into the threads. Then you put the indexing pin in this hole and hammer it down. Its just a little pin. A little rod. Then you have an index and can drill gas port, locate markings at TDC, drill for FSB pins, etc. Someone on here should be able to post a picture of the index pin. |
Because the extension is installed at the factory and will NEVER be removed. The gas port is drilled based on how the barrel extension is screwed in. If you want a photo of a barrel before the extension is installed then contact Randall of www.AR15barrels.com. He custom manufactures AR-15 barrels and will probably have such a photo.
It's a short pin that sticks out of the top of the barrel extension. It's about 1/16" in diameter and sticks out 1/10" of an inch or so. |
