mainly, because i have other people shooting my Rifles and we all set up differently.
Maybe "other people" should buy their own guns, then. They could set them up however they wanted, and wouldn't have to swap bits around every time they went out to shoot.
Or are you an armorer for a PD or something? If that's so, wouldn't it make more sense to assign a rifle to each individual, so they don't have to be reconfigured so often? I confess to not really understanding this.
I am kinda surprised we don't see more areas in the gun industry being developed by them. AK's,bolt action rifle stocks....
They only have so much capacity, and may not see projects in those market segments as profitable, right now. Or, they might be working on them and not talking, like they do.
