OSight has been releasing a series of optics and I've had the chance to spend some time with them. Previously I covered the clever recharging hood OSight S and OSight X which quickly became favorites thanks to those recharging hoods and enclosed emitters. I've also had some time with the OSight SE which uses a side-loading battery, but is also enclosed.
Now OSight is releasing more affordable options in the form of classic open-emitter design and side-loading batteries: the OSight C and OSight K.

I mounted them to the Tisas PX-9 Gen 3 Duty Comp and Canik MC9 Prime and hit the range to get a feel for the sights, and hopefully print osme better groups with those two guns than I did in the origina reviews. How do you think I did?
The new OSight C and Osight K are priced in the budget-friendly price range, but so far seem to be every bit as good of quality as the previously reviewed and enjoyed OSight S, X, and SE models I've been running for a few months now.
