The OP4 Buttstock and Hand Guards are replacement components for the standard
collapsable-style buttstock and carbine-length hand guards on AR-15 style rifles. They
are designed to mimic the aesthetics of the comparable components on Soviet AK style
rifles.
The combined set of the OP4 Buttstock and Hand Guards is designed to serve as a
training device for Soldiers operating in the role of opposing forces in a training
environment. The aesthetics aid to create a more realistic training environment by
eliminating confusion and helping to train Soldiers on the recognition of weapons
employed by an opposing force.
The OP4 Buttstock and Hand Guards utilize the same method of installation as the
standard collapsable-style buttstock and standard hand guards. No tools are required
for installation, allowing the user to quickly and easily change between standard and
OP4 components in a training environment.
