I have a 7.5" Bear Creek Arsenal complete upper, chambered in 7.62x39. Was picked up in a trade but I'm more interested in something chambered in .223/556 with a longer barrel.

looking to trade for:

-10.5" complete AR upper, preferably .223/556 but will look at 300 AAC

-complete 16" AR upper

Prefer straight trades but can go up or down depending on trade. Will come with 3 7.62x39 metal mags.
