Swapped from 223 to 300blk 🔥

Seems like a disaster waiting to happen.

While the premise is interesting. I would prefer to swap whole uppers instead of barrels as the optic on top wouldn't be zeroed for the second caliber if you just barrel swap

Right right good point all around

But why? When do you ever need to swap calibers in a tactical situation like that? And carrying around the second barrel with the gas port line sticking out like that seems like a good way to end up with a misaligned system. Cool idea but doesn’t seem practical.

Looks like an easier way to turn into Kentucky ballistics

Why do people do this when you can swap the entire upper with 2 pins and have proper holds with an optic? You can even have a suppressor and tuned gas block. (⁠╯⁠ರ⁠ ⁠~⁠ ⁠ರ⁠)⁠╯⁠︵⁠ ⁠┻⁠━⁠┻

Tactical skeleton makes them

Lol I will be staying far away from this. I can see my self not swapping the mag and blowing the thing up on accident.

Well, that’s a facial injury waiting to happen

Cool and all but much cheaper, and more effective to swap the whole upper…

I’d be afraid to get them mixed up
