Re: Quick detachable scope mounts?
larue, bobro, adm, all are good.
I prefer the bobro and larue, adm never seemed to be quite up to the same level of construction quality. Before I get flamed I can't say I've had any problems with ADM mounts I just wouldn't choose one over a bobro or larue if cost isn't a factor.
I've only ever used a QD mount on a carbine, but as far as that goes they all seemed to return to zero just fine. The bobro automatically adjusts for rails that might be slightly out of spec which is nice.
