Easier scope mounting than traditional G3-style rifles., We offer many HK G3, 91, & PTR barrels and trunions on our website. Some of these listed barrels are made right here in the USA, so they count as one US compliant part. We also offer H&K trunions that are from demilled G3 parts kits and will have left over receiver, barrel stubs installed along with factory barrel pins.
