Anybody know where I can find a 20 Practical upper? The 6mmAR.com website is down.

Talk to Mike at,
I suspect that it would take awhile to get it. But his work is worth the wait.

http://www.whiteoakarmament.com/ talk to John or Paul. Current wait is 16+ weeks on a Krieger. Pac-nor barrels have shorter lead times. Only 14 more weeks to go

Whoever you get it from, make sure the throat on their reamer is spec'd correctly if you want to be able to seat the bullets to the lands and have the cartridge still fit in the magazine. I have heard of reports of looooong throated 20-223 AR-15s being sold as 20 Practicals.

Need some help please on deciding the FreeBore. Have a Kreiger 1-11" and Pac-nor 1-8" on order for an AR15 project. Would like to shoot the Berger 40grs and the new 55grs out of magazine. The 55s will only work in the 1-8 and haven't been able to get a box yet. Anybody have some and can make a recommendation?

I think some people use long throats to avoid lawyers.long throat less pressure. that is how weatherby gets their hyper velocity. also some chambers with long throats shoot really well. just some thoughts.

You may have to throat the 1-8" long if you want to shoot those bullets without loosing too much case capacity and thus no way they will fit the magazine and touch the lands. You could always load them one at a time like folks who shoot the 600 yard stage.
If I were you I wouldn't chamber an AR-15 in 20 Practical to shoot those 55s. I would use a bolt rifle for them. Is there a reason you want to shoot them from an AR-15?
