I have an Rock River Arms LAR-15. It’s the kind with A2 flat top detachable optic mount with built in iron sight. Inscribed on the magwell is 5.56mm. Seems pretty straight forward. I know that 5.56 is the basically the same as .223 in caliber retrospect. The loads differ in pressure within the chamber. I haven’t shot 5.56 out of my rifle yet. Mainly because I want to be sure that this particular model can accept the 5.56 load. Any input would be appreciated
You should probably read every sticky in this section…

You retired? WTF, over?
Yep. :eek:
