AR15 with a Aimpoint. I'd love to grab my CCw instead, but only if i can find my glasses. I can aim a red dot without my contacts in, but not so good with my pistol. My cat loves to toss my glasses under the fridge while I'm sleeping, so the AR15 carbine wins my HD role.
My FN Ps90 with Aimpoint is a ton faster though. I'd like to try Keltecs new shotgun with a T1 on top.
I've got a Larue 13" rail on my carbine, a chainsaw fits right under my barrel just fine. But I'm having trouble putting a bayonet on the chainsaw.
