Friday morning, about 8:45, while standing in front of the barn, I got a chance to talk with a gentleman who had built a hybrid AR180 with an AR 15 barrel assembly, rail system and all.
Seemed to have an Bushmaster M4 barrel, now that I think about it. Probably the best thing I saw all day now.
But in my haste, I didn't find out anything about the conversion other than the guy did it his self and he had at least 40 hours invested in milling and lathe work.
There were at least three other guys talking to this gentleman and I hope somebody that saw the weapon will read this post and fill in some information.NEED TO KNOW AND WOULD LOVE TO SEE PICTURES. Thanks to anyone who can help.
