PMC X-TAC 5.56 NATO M855 62 GR FMJ 20/bx (556K)

This X-TAC 5.56 NATO penetrator ammo contains the M855 bullet, which is a steel-tipped lead core bullet. This 5.56 round pierces deeply and deforms less on impact than standard FMJ rounds, while also providing increased stability and accuracy. This PMC 5.56 NATO ammo is a reliable, affordable military-strength cartridge that fires from most AR-15s for training and target shooting.
