So, naturally

The scope-mount options for the Rossi are limited, vs. the Marlin, but since I was using a Holographic sight, position and eye-relief are not at all critical. I had a B-Square 'no-gunsmithing' mount I wasn't using, which has the added 'advantage' that you can take it off quickly and make the gun look all 'normal' again (I'm not sure why I would particularly want to do that, mind you, but it is important to some folks).
For the light-mount, I wanted either something quick-detachable (because the light is something I may want to remove sometimes, for instance hunting with a light is illegal where I live). So, I thought about a 'scalloped' version of the PVC-mount I used on the Marlin, but found an unused 'weaver scope base' that just happened to have the same radius concavity on the underside as the radius of the .45 Colt magazine tube. After considering sweat-soldering (thanks for the edjumication on that, guys

The forend already bears scars from my previous Bubba-smithing of the forarm band when I mounted a sling swivel stud in it.

Anyway, Here's the Pics:

The Coast (link) LED-Lenser (Model P-7) 190-lumen light

(One nice thing about the LED-Lenser is that the first button-push gives you bright 190-lumen light, then the next button-push gives you a dim, battery-saving, non-blinding, light option. The scope rings hold the 'focus' ring in 'spotlight' mode.)
(One thing - I should have got the black one):

I switched the Burris mount screw so the knob was on the left, keeping the ejection (& iron-sight) area uncluttered:

Here's the Marlin for comparison:


The three-shot group which follows was shot at 50 yards - nothing all that exciting, even for a 'levergun' - - - BUT WAS SHOT IN PITCH BLACK CONDITIONS AT MIDNIGHT... Sure, a gizmo-equipped $2,000 AR-15 Shorty with night-vision CAN do that or better - but with blinding muzzle flash, deafening muzzle blast (unless you actually want to wear hearing protectors whenever you go out to check your livestock), and four or five times the cost. Hopefully, I can 'hit the quarter' next time I shoot in the dark...
