Picked up a MRT for the daughter a few weeks back. Managed to rummage through the parts bin and piece together a box with APS internals (failure inevitable), a bruisemaster 35cm Barrel and an X-force high torque motor.
Enjoyed working on this one. Solid receiver and foregrip. I made a few small mods to the front of the lower receiver for ease of service. Cutting a hole so the T piece can slide through, enabling the whole top of the receiver removable without the barrel Tpiece dance.
Stock spring and 80% ported cylinder still pumping out 260fps.
Daughter stoked, so that’s a win
