| Is the bolt that comes with a 22 pistol upper capable of tripping a RLL? |
|
Quoted:
I have not heard of anyone getting a .22 upper (dedicated or conversion) to work with a RLL. This is one of the main downsides to a RLL IMHO. Hasn't been done, and isn't likely ever to be done, because the LL is under constant tension from the disconnector spring when the firearm is in battery. The rifle buffer spring is capable of keeping the bolt closed and locked against the disconnector spring tension. The .22 conversion kit return spring is not capable of keeping the bolt closed against the disconnector spring tension. This inability to remain in battery exacerbates bolt bounce, and reduces the timing window available for the hammer to get a clean strike on the firing pin when firing in automatic mode. The timing window that's left has proven too small and variable (recoil impulse differs minutely from round to round, kits get dirty, harmonics cause friction spikes in weird places during the counter-battery and battery strokes) to get a 22 running reliably with a lightning link, to date, although many persons including myself have gotten the kits to function mechanically/statically with a lightning link. What's needed is a trip mechanism which isn't under spring tension in battery, then can reset to actuate the disconnector during the counter-battery stroke, like the auto sear does. If it were possible to get the tension off the LL trip in battery, I think then an LL could be made to work reliably with the 22s. |
