The Maple Ridge Armoury SLW Upper Receiver Assembly is precision machined from billet 7075-T6 aluminium. The design dispenses with the forward assists and utilizes a shortened shell deflector to achieve the slimmest profile possible in a very lightweight receiver.
The profile of the Maple Ridge Armoury SLW upper receiver mates seamlessly with the Maple Ridge Armoury SLW series of handguards for an innovative, snag free design.
