I got a little more work done on the 17hmr bolt for an ar15. I got the bottem front of the bolt cut, charging handle cut, and the (gas) key cut. I still need to: make a hammer cut; finish milling out the bolt face from a circle to an upside down "U" which will remove the feed lip; turn down back end for .930" tube to bring it up to length; firing pin channel and retainer; extractor cut. I debated leaving the feed lip on, but thought it might accidently set off a rimfire round if it got bent as it is quite thin. The extractor cut will have to wait until I get a 17hmr barrel to match up the cut to the barrel. If anyone knows a source of cheap 17hmr barrels I'm all ears! Here's some pics of it so far.
