We present NuSTAR and Swift observations of the neutron star Aquila X-1 during the peak of its July 2014 outburst .
The spectrum is soft with strong evidence for a broad Fe K \alpha line .
Modeled with a relativistically broadened reflection model , we find that the inner disk is truncated with an inner radius of 15 \pm 3 R _ { G } .
The disk is likely truncated by either the boundary layer and/or a magnetic field .
Associating the truncated inner disk with pressure from a magnetic field gives an upper limit of B < 5 \pm 2 \times 10 ^ { 8 } G. Although the radius is truncated far from the stellar surface , material is still reaching the neutron star surface as evidenced by the X-ray burst present in the NuSTAR observation .
