I think that's pure awesome. In theory, one would not have to ever touch the bolt carrier with one of those puppies, which means no HK slap, but it's not possible to HK slap a G36/SL8 anyway. I think the demand for these is there, just the G36 and SL8 owners on this board are not entirely sure of what it does, and thus are not demanding it. But perhaps that will change with time.
