I was procrastinating the other day, and I found myself researching AR pistols for close quarter fighting, with emphasis on inside the home and on urban streets. The urban street scenario is admittedly a self indulgent SHTF fantasy/paranoia. Although, localized breakdowns of civilization do sometimes occur. So, I think it's scenario that can be entertained without donning the aluminum foil beanie protectors. Anyway, as I meandered the world of AR pistols and SBRs, I was reminded of the bullpup. Many of these have an overall length close to that of 10.5" barreled SBR, but achieve this with a 16" barrel. This means that you can shoot conventional 5.56 ammo without loss of effectiveness and increase in noise that you get with a 10.5" SBR. The only practical limitation I can see is that the brass will eject to your face when you shoot weak side (a known issue for some designs). I hear triggers are not as crisp due to the long linkage mechanism needed to span the action being behind the trigger. But, CQB is not precision work. I see that some foreign militaries are adopting the bullpup in place of the carbine. Israel being an obvious example. Does anyone here have experience with a bullpup? Which bullpups have you tried? What was your experience like? If you abandoned the platform, what was the deal breaker for you?
