I have multiple BCA uppers for sale. Narrowing down my collection to focus on specific calibers. List below:

6mm Arc 18inch (includes mag(s)) side charger

6.5 Grendal 20inch (includes mag(s)) side charger

The uppers themselves are $100 per (includes mag(s), BCG's

I have ammo for each, and will price that out seperately.
