I want to emphasize my above comment was made specifically to avoid the "conventional vs bullpup" debate, because it is a separate one from the "intermediate caliber vs full size". I can not stress this enough.

The benefit of having a full length barrel in a shorter package looks amazing on paper, but in practice isn't as big a deal for most purposes.

Bullpups introduce issues like an upper limit on how good the trigger can be because of a needed linkage, and I think more pressing is making something as simple as brass ejection a bit of a head scratcher to make work for both left and right handed people. There are solutions but they aren't necessary if you just don't deal with bullpups.

Since AR-15 derived designs are the most popular military rifles worldwide, I'll mention that the straightline recoil and beefy buffer assembly are appreciated and that impulse can't really be replicated in a bullpup design.

Now, I feel it in my bones that you want to argue for the merits of bullpups. Maybe I'm wrong but I just get that sense. I genuinely have been a part of so many bullpup conversations and I honestly don't care about it. Bullpup vs conventional is a boring argument. If you're still wanting to continue a discussion/debate/internet argument please direct an angry correspondence to the French military about their dropping of the FAMAS for HK416s.
