I've got a bushmaster 308 rifle .... the RRA LAR-8 is a clone of this rifle.
I have called RRA to confirm that barrels, uppers lower bits etc are interchangeable.
These use FAL magazines. I've got three 20 rd and one original bushmaster 5 rd.
Nice condition, replaced plastic with free float tube.
$1000 local to las vegas valley or $1050 shipped to your FFL complete
