For my contribution, I give you the Sig 710
The SIG MG 710-3 is an automatic, air-cooled belt-fed weapon operated by roller-delayed blowback and fires from an open bolt. The machine gun's bolt differs from other contemporary designs employing the short recoil method of operation (such asCETME and Heckler & Koch designed weapons), being a 3-piece design that consists of a bolt head with two locking rollers, a striker sleeve and the bolt carrier which is connected telescopically with the bolt head. When a round is chambered pressure from the return spring drives the bolt and carrier assembly forward; simultaneously both rollers engage camming surfaces which drive the rollers outward from their compressed travel position into recesses in the barrel extension. Upon firing, the bolt carrier and striker assembly recoil to the rear and the geometry of the fixed camming surfaces drives the rollers inward unlocking the bolt breech and increasing the speed at which the striker sleeve withdraws relative to the bolt. As the slower bolt continues rearward it impacts the returning striker sleeve (this impact decelerates the bolt). The bolt assembly also contains the spring extractor, while a lever case ejector is located at the base of the feed tray. Spent casings are ejected downward. The weapon has a striker firing mechanism, a trigger assembly for fully automatic only fire and a cross-bolt safety (the "safe" setting disables the bolt catch). The SIG MG 710-3 is fed from the left side by either NATO standard disintegrating M13 (U.S.) or continuous link German DM1 belt, but only after swapping several parts in the feed block. When used in a light machine gun role, the ammunition belt is stored in a sheet metal container that has a 50-round capacity and is attached to the left side of the receiver. The feeding mechanism resembles the one used in the MAG machine gun (a simplified version of the MG 42's feed system) operated with a feed arm driven by the motion of the striker sleeve. The belt is fed in two stages during both the forward and rear movement of the bolt assembly. The quick-change barrel, ended with a slotted flash suppressor, has a fixed handle used to remove it. The machine gun uses three types of barrels: a light profile, heavy profile (in a heavy machine gun role), and special type (used for firing blank ammunition). The firearm has a fixed stock (metal or wood), detachable bipod and open-type sights (rear sight is a sliding tangent with settings from 100 to 1200 m with 100 m increments). Used as a static heavy machine gun the weapon is placed on a SIG L810 tripod. It is also adapted to use an optical sight (with 2.5x magnification) or a night vision device. http://en.wikipedia.org/wiki/SIG_MG_710-3 |

Japanese Type 62 Machine Gun
The Sumitomo NTK-62 is a gas operated machine gun chambered in the 7.62mm NATO cartridge, belt fed with the use ofM13 disintegrating links.[url=http://en.wikipedia.org/wiki/Sumitomo_Type_62#cite_note-MF-3][3][/url] It has an unusual feed tray as the pivoting lever is above the bolt in the receiver rather than in the feed tray cover found on most machine guns. |

Quoted: Too good of a thread idea to let go. The Ultimax 100, probably well known in the circles here. http://i50.tinypic.com/1430ys0.jpg http://upload.wikimedia.org/wikipedia/commons/7/73/Section_Automatic_Weapon.jpg View Quote View All Quotes View All Quotes Quoted: Too good of a thread idea to let go. The Ultimax 100, probably well known in the circles here. The Ultimax 100 is a gas-operated automatic weapon (capable of fully automatic fire only) with a short-stroke gas piston operating system powered by ignited powder gases diverted from the barrel through a port in the gas block. The Ultimax 100 is a locked breech weapon with a rotating bolt that contains 7 locking lugs. It fires from an open bolt position. http://i50.tinypic.com/1430ys0.jpg Widespread adoption of the design might have been compromised by its feed system. The original Ultimax 100 was meant to be used with a drum magazine holding 100 rounds. Unfortunately, the drum magazine was bulky. It was also difficult to reload without a special mechanism. The shape of the drum magazine also occupied more space compared to M16 magazines or the FN Minimi box holding a belt of 200 rounds. The machine gunner also could not take magazines from other squad members who were equipped with M16s http://upload.wikimedia.org/wikipedia/commons/7/73/Section_Automatic_Weapon.jpg The drums were designed to be disposable (issued loaded and thrown away after use) - source: discussion with CIS head designer, 1984.

French AA52
The AA-52 (full designation in French: Arme Automatique Transformable Modèle 1952, "Transformable automatic weapon model 1952"), also known as "La Nana" is one of the first French-produced guns of the post-World War II era. It was manufactured by the French government-owned MAS company. The AA-52 is still used today as a vehicle-mounted weapon due to large quantities in service, but has been replaced in the helicopter role by the Belgian FN MAG, starting with the EC 725 Caracal of the Special Operations units and the Air Force Search and Rescue teams. |

Hungarian KGK
The KGK universal (general purpose) machine gun was produced in Hungary during the 1960s and 1970s. It is based on the Soviet Goryunov SGM medium machine gun, adapted to a universal role by the installation of a pistol grip below the receiver and a rifle-type shoulder stock, which replaced the dual spade grips of the original SGM. It was used by Hungarian army on a limited scale and was later replaced by domestically produced copy of the Kalashnikov PKM machine gun. The KGK universal (general purpose) machine gun is gas operated weapon with long stroke gas piston which is located below the quick-change barrel. It fires from open bolt, in full automatic mode only. Barrel locking is achieved by tilting rear part of the breechblock to the side, where it locks into the cut made in the receiver wall. The SGM / PK type non-disintegrating steel belts with closed pockets are used to feed the KGK, and similar belt boxes can be attached below the receiver. Gun is equipped with integral, folding bipod, and also can be used from lightweight folding tripod with AA adapter or from various vehicle mounts. |

Seeing a lot of mg42 clones...
Also the ultimax isn't really a gmpg |

now for some big iron: https://en.wikipedia.org/wiki/KPV_heavy_machine_gun The KPV-14.5 heavy machine gun (KPV is an initialism for Krupnokaliberniy Pulemyot Vladimirova, in Russian as ???????????????? ??????? ???????????, or ???) is a Soviet designed 14.5x114mm-caliber heavy machine gun, which first entered service as an infantry weapon (designated PKP) in 1949. In the 1960s the infantry version was taken out of production because it was too big and heavy. It was later redesigned for anti-aircraft use, because it showed excellent results as an AA gun, with a range of 3,000 meters horizontally and 2,000 meters vertically against low flying planes.[1] It was used in the ZPU series of anti-aircraft guns. Its size and power also made it a useful light anti-armour weapon on the BTR series of vehicles and the BRDM-2 scout car. View Quote https://en.wikipedia.org/wiki/14.5%C3%97114mm a 920 grain projectile with a muzzle velocity the same as M193 out of a 20" barrel (3300 fps). ouch. |

They're expensive enough that you could get into the auto game for less money (not an auto m60, obviously). M60s feel chincy as it is.. A super expensive closed bolt semi auto might be fun for a day, but the novelty will wear off quickly. I'd keep saving for the real deal. Just my semi-educated opinion. Good luck either way. My dream is a transferable 240 (yeah right). Eff the ATF and the NFA and 86 ban.

5.56mm SAW type weapons, Bren guns and the ultimax all are not GPMG.
A GPMG is a belt fed, rifle caliber (not intermediate) mg with a quick change barrel that can be fired from various configs bipod, tripod, Vechicle mounted. |

The Mk48, probably not very well known outside of SOF or some Infantry units. I've seen them used on a support by fire although it's not common, probably stretching the definition of a GPMG. They do have a quick change barrel, never put on on a tripod though. Grab it over the 240L every chance I get

They are ergonomically retarded and suck for infantry and carrying. I was very happy when I got to group and we had MK48's. The only people I ever heard saying they liked the 240's were those NOT in the infantry, although I'm sure there must be some, somewhere that do. The worst thing that ever happened was getting rid of the 60. It's handgauard was actually positioned so that humans could hip fire the weapon instead of having to be an ape. I was happy to see a few years ago that the army was testing new M60's. I hope for the guys taking my place as I retire they get rid of that POS 240. |
