Sure!

Right here in the armor forum you'll find my Hobby Boss M4 HST. Other than two small brass chains on the opened amo bin, the model is completely stock, built straight from the box.

In my last video on youtube, the AFV Club M3A3 was built OOB and then I added some scratch built stowage on the back. I didn't alter/correct anything on that kit.

I don't always build OOB, but it really depends on the topic and/or kit I'm building. Sometimes I will spend a great deal of time fixing/adding stuff, other times I assemble the kit warts and all in a matter of a couple days.
