I've been leery of the quick disconnect AR scope mounts because of the return-to-zero question. I assumed it was hollywood being hollywood. The reading I've done on the AR QD mounts indicates they return pretty close to their original zero. So, I suppose it's not as far-fetched as I had always assumed when seeing it in the movies.
