Only the top one might work with a tweak of where the glocks sit. You would also have to ensure the chambering isn’t interupted or obstructed. The bottom one concerns me on the fact that you have a quad barrel AR-15 weapon. But you have only one bolt to prime atleast 2 bullets in two seperate chambers. How the front bullets are going to be primed is beyond me as you would need an incredibly quick action to prime the front bullets before the bullets behind catch up. Though it is a quad barrel so you have like 2 more chambers with a seperate barrel set than the other two. Though I’m lost on how thats gonna be cocked as well.
