I have a couple of the original models that I mounted Eotech's on and find them great for new and/or young shooters when shooting from a bench. The Eotech simplifies sighting, just put the dot on the target, no worries about sight alignment. And shooting using the bipod for support is very stable, a newbie is able to shoot well right away with a gun that fits virtually anyone given that the Eotech eye relief is works at almost any distance and there is no issue of proper stock fit for length of pull.
As for myself, I find the EO-equipped Charger to be a ton of fun, with or without bi-pod support. The little guns shoot quite well right out of the box. Using a rifle type hold I've been able to score consistent hits on a 4" spinner at 100 yards. It might not be everyones cup of tea, but I get a lot of enjoyment out of mine. Well worth the relatively moderate price of admission.
I like the original model quite a bit and don't know if I'll see enough gain to add a new standard model, though I think the changes make an already good thing even better. That little takedown has me very intrigued however, and if I can find a good deal on one I'd sure like to add it to my collection.
