Folks can debate the merits of such a design. Regardless, it’s a pretty nifty look.
My initial thoughts on the merits and demerits are thus:
+ reduced weight
+ reduced materials
+ advanced engineering structures can in fact be stronger than solid members (we see this in architecture all the time, where a beam is designed to direct the flow of forces providing far far more strength for the weight)
– open areas provide places for objects and dirt to get into and cause jams
– impact durability is reduced
Okay, now with all that said, is it just me…or do you want to paint this red and blue and add a launch tube to shoot sticky nets, and call it the “SpidAR Gun”
Something akin to this cycle but done to a skeletonized AR15.
