Ohio Ordnance Works FN M16 barrels?

[Bowser]

Does anyone have any experience in regards to these FN M16A2 barrels and uppers from Ohio Ordnance Works? I emailed them and they just told me that "the only markings are on the barrel, I’m not sure who made the rest of the receiver. To the best of my knowledge, it is surplus from a military contract. It has the original feed ramps, not for an M4." I'm worried about major throat erosion. I want to build this into a service rifle I can shoot at the local club.

I have two of them. One in FN A2 upper and another in a Colt A1 upper. Their accuracy is on par with my BCM A4.

Can anyone post a picture of these to show the condition?

Left A2 and middle A1 have the OOW barrels. I received both in good condition and have proven to be on par accuracy wise with my BCM and LMT rifles.
