Have you shouldered and fired one with an optic (especially an ACOG or Lucid type)? Taken it down and reassembled it quickly? If you had, I'm quite certain you wouldn't be defending it quite as passionately.
And I never once said it was ugly. Unholy aberration yes, but not ugly.
It's really
not so "horrible" with an optic on it....

...I have a simple 3-9x scope atop see-through extra-high rings on mine, and while I cannot "co-witness" with the sights

, I can
very easily and comfortably "transition" (oh, look at me

, using the "go-fast" cool operator words !

) from the irons to the scope & back again (and at a 3x setting o nthe scope, it's all good).
Plus, as much as I like the SU-16 (it's fun and "nifty" - when did so many here become curmudgeons ? ) , the MR-1's "pencil barrel" will definitely produce better/more accurate results....
Sorry, didn't mean to offend anyone !
Oh, and if I can do a "takedown" of the MR-1, anyone can - really,
anyone can ! It's far more a question of "(upper) body strength" and knowing what and where and when to push, than it is about anything else...kind of like***, come to think of it....
