Up for sale is a Massachusetts-legal fixed-magazine AR-15 in .223/5.56, built right.
 
Brand-new Dark Storm DS-15 multi-cal lower (DSI's compliant fixed-magazine configuration) mated to a used Bushmaster 20in dissipator upper -- full-length handguards, A2 front sight, detachable A2 carry handle, and a clean bare muzzle. Collapsible stock, S&W grip.
 
This is the intelligent way to run an AR in MA: no games, no gray area, just a solid compliant rifle that shoots. The lower is new and unfired; the upper has honest light wear.
 
We have visually inspected and function checked this firearm, but it has not been test fired.
 
Any questions, reach out to Bay State Surplus.
