Regular guy. I hear you. I only ever wanted ONE of each niche need. 1 M-4 (Frankengun), 1 pump-gun (870 bullpup), 1 s/a 12ga. (Benelli M4), 1 SBR carbine (COLT 9mm 10"), 1 SBR .308 (G3K), 1 bolt gun (Rem. 700). With the exception of my MARK 23 addiction(1 is a shooter, 3 are BNIB collectible to sell later) and a recent indulgence of the MR762SD...I'm good.
Now that I list them, it's not brief, but I still don't get guys that have 10 M-4's, unless they plan to arm the whole HOA for civil unrest or Zombies.
