I have a discontinued ACR stock with a Dan Haga Bren 2 adapter. Both the stock and adapter have been discontinued. Several companies make adapters to fit the ACR stock on B&T, MP5s, AKs, Jakls, SCARs, etc.
giving local guys a chance to snag this before I list it on GB for penny auction. These are listed on GB for $900 but willing to take $500.
Firm on price but open to trades
