I am wondering if someone makes a .223/5.56 upper receiver an/or bolt that doubles as a bolt-action? One that is a semi-auto with ability to lock or unlock the bolt when needed???? Where would I begin to look for something like this? Thanks |

David Tubb uses one for shooting highpower rifle matches. I think it is actually built on an AR-10/SR-25 style lower receiver though. This isn't just an upper but definitely neat though. Info can be found here: www.zediker.com/tubb/tubbgun.html Here's a picture:

Some semi-auto military rifles have gas cut-off valves that let you convert them to straight pull bolt action rifles. Typically this feature is used for grenade launching. The M-14 (and the semi-auto civilian version, the M1A) have this feature. I don’t know of anyone who makes such a valve for an AR, but I’d think any competent machinist could do it. Incidentally, the topic of converting an AR to a straight pull bolt action has been brought up before on this forum by members living in Pennsylvania who cannot hunt with a semi-auto. |
