Hey guys question about .40/10mm. I have a oly 40 upper for the AR. Now best I can tell the olympic arms mags for a .40 and 10mm upper are the same mags(got to confirm that though) If thats the case, and I want to go 10mm can I just have the barrel rechambered to 10mm? If I do that can I still shoot .40 out of it if I wanted to? just thinking about it so I thought I'd ask. Ok I forgot this part. The upper will be chopped down eventually as part of an SBR project when/if(depending on a new AWB) I pick up a pre-ban lower. Thanks |
| I don't think you can shoot .40 & 10mm out of the same chamber because the cartridge headspaces on the case mouth. If it's chambered for 10mm the .40s would be to far forward. (Unless the extractor held onto it tight enough--I've seen a 9mm fired in a .40 that way, but it wasn't pretty.) |

Quoted: There the modified 41AE Uzi mags correct. They have already been modified to feed the 40 so they should not need to be modifed anymore. |

Oly will need to pinch your mags to fit the longer 10mm round. You can find out more about a 10mm Oly AR here: [url=http://www.bren-ten.com/main-site/id17.html]Very Cool 10mm Oly Setup[/url] |
