Zastava USA PAP M77 Features The Zastava USA PAP M77 centers on a barreled action built with a bulged front trunnion a design that reinforces the critical junction between barrel and receiver to handle the pressures of repeated 7.62 X 39 firing without loosening over time. The 1.5mm receiver is noticeably thicker than many stamped AK receivers adding rigidity that keeps the action tight through heavy use. A chrome lined bore protects the barrel from corrosion and heat erosion extending service life and easing cleaning after extended range sessions. The 19.7 barrel length keeps the rifle balanced and maneuverable while still giving the 7.62 X 39 cartridge room to develop its full ballistic potential. The threaded muzzle on this PAP M77 ships without a muzzle device installed so the owner chooses and installs a brake compensator or flash hider that suits their intended use. A stock bolt is included allowing the installation of a buttstock of the owner s choosing to complete the rifle. The semi-automatic action cycles reliably off a 20-round magazine though the magazine itself is sold separately from this barreled action. Built on Zastava s proven AK pattern manufacturing the Zastava USA PAP M77 gives builders and AK collectors a dependable foundation for a personalized 7.62 X 39 rifle project available for sale at GrabAGun.
