GUN PORN OPERATING The bolt and carrier design are similar to the AK. The bolt and bolt carrier are however oriented upside down compared to the AKM, with the piston and gas system being underneath the barrel. The PK machine gun series is an open bolt design, which improves heat management during automatic fire compared to closed bolt designs and helps avoid- ing the „cook-off", wherein the firing chamber be- comes so hot that the propellant contained in a cham- bered round unintentionally ignites, making to weapon fire until the ammunition is exhausted. Open bolt de- signs typically operate much cooler than closed bolt designs due to the airflow allowed into the chamber, action and barrel during pauses between bursts, mak- ing them more suitable for constant full-automatic weapons such as machine guns. The 7.62x54r PKM is fed from 100 round non-disin- tegrating metal belts and 200 or 250 round ammuni- tion boxes. For short time the belts were fixed-length buy they were replaced with 50-links long parts. Dur- ing the shooting with blank ammunition, the blank-fir- ing adapter must attached to the barrel and special frame must be installed in feed tray. in early 2000's The PKP Pecheng (russian: Печенег) general-PurPose Machine gun, based on PKM was devel- oPed and becaMe new gPMg in russian arMed forces. in 1990's The 7.62x51MM naTo chaMbered PKM varianT was develoPed and finally, afTer decade, iT becaMe The uKM- 2000, now sTandard issue gPMg in Polish arMed forces.
