Hi Rudy,
I have a random question... Is there a particular reason why the USC mag block conversion doesn't work with barrels shorter than 11"? I know you said it malfunctions but is there a specific reason why? |

Best I can figure, it is because the way the round is presented (nose high) and where it drags on the bolt carrier (relatively far back in the magwell) it just robs too much energy from the bolt carrier on the recoil stroke.
Trying to make time to see how short we can go with the new adapter and mags.......I'm running an 8 inch full auto and locking back on the last round  Soon as we get through the new website launch, I'm gonna just start cutting a barrel 1/2 an inch at a time ands see where it goes.
