You dudes who called it an "Tinkerer's Gun" nailed it perfectly. It truly lends itself to tinkering. Mind you... so does any of the AR15 platform and it's variants! All good fun, but the AR is still restricted and will / can never be a truck gun for that reason.... unless the PConservatives are reading this thread and trying to tweak their next election platform.
Once you get that rifle sweet spotted, then you are good to go! That's where our advice comes in handy!
For the newbies here... back in 2009; I was invited by a Law Enforcement Agency (which will remain 'un-named')

to deliver a clinic to their armorers. These master craftsmen not only had their skills dialed, their comfort level soared even higher after I finished with them in the morning! They showed me pages and pages (in binders) of their targets shot with the

CHU wood stocked Norc M14's. All these groups were sub MOA with Fed Gold Medal Match ammo!

How awesome is that?
So... yeah, can they shoot? Well YEAH, even more so with a little bit of tweaking, and that's where and why I do the M14 clinics for you tinkerers; that's so that yer dicks don't fall off!
Besides, truck guns (Can-Ammo Shortys) are always fun!
Heeeeere kitty, kitty, kitty!
