The M16A2 buttstock is about five/eight" of an inch lengthier then the sooner versions. As a result of greater duration it employed a longer buttstock screw and a spacer. The swivel is mounted closer towards the buttplate. This buttstock is at this time used to the M16A4: Many thanks for https://waylonrabzw.rimmablog.com/30647514/top-guidelines-of-gold-cup-trophy-colt-45
