The Black Rain Ordnance Outflow XL 5.56 suppressor is the extended-length version of the Outflow, a titanium can rated for .223/5.56 NATO (brand part no. BRO-OUTFLOW-XL). The longer body gives it more internal volume than the standard Outflow, the usual reason to choose an XL model. Titanium keeps the added length from weighing down the front of the rifle. It suits an AR-15 that spends long range sessions suppressed, or a 5.56 rifle where the extra length is not a concern. Shooters who already like the Outflow design and want its larger form should start here.
