machine gun","price":75.0,"description":"Full assembled model of HK21E LMG, 7,62X51 NATO bullet, assault grip, belt for 50 rounds, belt box and bipod.\n\nModel is good for weapon mechanic animation, games and for visual education.\n\nNotification: if You need low poly model You can contact me here or : 27608166@mail.ru (too many polygons is because of belt and 50 bullets in assembly)\n\nThe HK21 is a German 7.62 mm general-purpose machine gun, developed in 1961 by small arms manufacturer Heckler \u0026 Koch and based on the G3 battle rifle. The weapon is in use with the armed forces of several Asian, African and Latin American countries. It was also license-manufactured by Fábrica de Braço de Prata in Portugal as the m/968 and in Mexico by SEDENA as the MG21. In the German military (Bundeswehr) and the federal police (Bundespolizei) it is designated \"G8\".\n\nThe E model is a thoroughly revised variant aimed to improve the reliability, efficiency and service life of the weapon. For this the length of the receiver was increased by 25 mm (1.0 in) to provide additional recoil length for the bolt group. The recoil reduction improved accuracy of fire. Reinforcing bars were added to the receiver to provide additional strength and a guaranteed 60,000 rounds minimum service life. The bolt head, extractor and locking roller holder were completely redesigned as were the bolt carrier and recoil spring assembly, belt feed unit, buffer, barrel and trigger group. The redesigned belt feed mechanism transports the ammunition belt in two steps reducing stress on the feed and ammunition belt.\n\nCompared to the older HK21A1 and HK11A1, the modernized \"Export\" weapons also feature a longer barrel shroud, extended by 94 mm (3.7 in) towards the front, which also resulted in a longer sight radius; the barrel trunnion was modified (the HK21E also received a longer barrel); a burst fire mode was incorporated into the trigger group as the fourth selector setting (3-round burst); a polymer barrel handle was added; space for a cleaning kit was added in the grip; the rear sight was modified with an adjustable drum; a bipod with a 3-position height adjustment and 30 degree tilt mechanisms replaced the simple folding bipod; the feed mechanism was modified to provide continuous feeding (by moving the belt in two stages, during both forward and rear movement of the bolt), a forward assist for silent loading was provided and the machine guns were adapted to use NATO-standard optical sight mounts.\n\nWhen employed in the light machine gun (infantry assault) role, the HK21E stores its ammunition belt in a 100-round sheet metal container, fastened to the bottom of the feed mechanism (as in the HK21A1). The ability to use G3 or STANAG (for HK23E) box or drum magazines is available with an optional feed module kit that consists of the bolt, recoil spring and belt feed module or magazine well. When employed in the belt-fed medium machine gun (fire support) role the HK21E provides a cook-off rate in excess of 1,000 rounds fired in quick succession. The shock-absorbing tripod weighs 10.5 kg (23.1 lb).","imageAlt":null,"url":"https://www.cgtrader.com/3d-models/military/gun/hk21e","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/7KUGCNfwJokTn757hRMR6W8T/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/H%26K21.jpg","gridUrl":"https://media.cgtrader.com/variants/7KUGCNfwJokTn757hRMR6W8T/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/H%26K21.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-models/military/gun/hk21e","isCgtVerified":false,"types":{"printReady":false,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":12,"name":".obj","is_native":false},{"id":29,"name":".ige","is_native":false},{"id":5,"name":".fbx","is_native":false},{"id":72,"name":".stp","is_native":false}],"categorySlug":"military","subcategorySlug":"gun","categoryTitle":"Military","subcategoryTitle":"Gun","schemaImageUrl":"https://img-new.cgtrader.com/items/2327899/10374bcf2d/hk21e-machine-gun-3d-model-10374bcf2d.webp","saleOffDiscount":50,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"2207136","type":"listingItem","attributes":{"id":2207136,"title":"Heckler  Koch G3","price":75.0,"description":"UPD: Corrected mistake, added extracting port .\n\nFull assembled model of german infantry rifle G3A3 and 7,62X51 NATO bullet. \n\nModel is good for weapon mechanic animation, games and for visual education.\n\nNotification: if You need low poly model You can contact me here or : 27608166@mail.ru\n\nThe G3 (Gewehr 3) is a 7.62×51mm NATO, select-fire battle rifle developed in the 1950s by the German armament manufacturer Heckler \u0026 Koch (H\u0026K) in collaboration with the Spanish state-owned design and development agency CETME (Centro de Estudios Técnicos de Materiales Especiales).\n\nThe G3A3 is a selective-fire automatic weapon that employs a roller-delayed blowback operating system. The two-piece bolt assembly consists of a breech (bolt head) and bolt carrier. The bolt is held in battery by two sliding cylindrical rollers that engage locking recesses in the barrel extension. The breech is opened when both rollers are compressed inward against camming surfaces driven by the rearward pressure of the expanding gases upon the bolt head. As the rollers move inward, recoil energy is transferred to the locking piece and bolt carrier which begin to withdraw while the bolt head slowly moves rearward in relation to the bolt carrier. As the bolt carrier clears the rollers, pressure in the bore drops to a safe level, the bolt head is caught by the bolt carrier and moves to the rear as one unit, continuing the operating cycle. The bolt features an anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The \"bolt head locking lever\" is a spring-loaded claw mounted on the bolt carrier that grabs the bolt head as the bolt carrier group goes into battery. The lever essentially ratchets into place with friction, providing enough resistance to being re-opened that the bolt carrier does not rebound. The spring-powered claw extractor is also contained inside the bolt while the lever ejector is located inside the trigger housing (actuated by the recoiling bolt).","imageAlt":"Heckler Koch G3 3D","url":"https://www.cgtrader.com/3d-models/military/gun/heckler-koch-g3","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/S6yCB1Rv7rUvQWc5UK8ZbhjP/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/H%26K%20G3.jpg","gridUrl":"https://media.cgtrader.com/variants/S6yCB1Rv7rUvQWc5UK8ZbhjP/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/H%26K%20G3.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-models/military/gun/heckler-koch-g3","isCgtVerified":false,"types":{"printReady":false,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":5,"name":".fbx","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":72,"name":".stp","is_native":false},{"id":29,"name":".ige","is_native":false}],"categorySlug":"military","subcategorySlug":"gun","categoryTitle":"Military","subcategoryTitle":"Gun","schemaImageUrl":"https://img-new.cgtrader.com/items/2207136/aaedbc0efa/heckler-koch-g3-3d-model-aaedbc0efa.webp","saleOffDiscount":50,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"2255263","type":"listingItem","attributes":{"id":2255263,"title":"PSG-1 rifle with scope","price":75.0,"description":"Full assembled model of german sniper rifle PSG-1 maded om infantry rifle G3 base and 7,62X51 NATO bullet.\n\nModel is good for weapon mechanic animation, games and for visual education.\n\nNotification: if You need low poly model You can contact me here or : 27608166@mail.ru\n\nThe PSG1 is mechanically based on the G3 rifle and features a low-noise bolt closing device (similar to the forward assist on many M16 rifles).

The 1990 part is the year was the sniper rifle was made.\nThe Heckler \u0026 Koch MSG90 was first introduced in 1987. It uses a delayed blowback design the same as many other H\u0026K rifles. Based on the Heckler \u0026 Koch PSG1, it is designed for military and police use. It was designed to meet the military specifications of the US Army's M24 Sniper Weapon System.\nIt has several improvements over the PSG1. The barrel is lighter and shorter. It is made using the cold hammer forging process. The stock is adjustable and of a different shape. The trigger is wider and has a 3.3 pounds (1.5 kg) trigger pull set from the factory. It does not have open sights but comes with a 10-power Telescopic sight.\nWhere the PSG1 did not stand up to rough handling on the battlefield, the MSG90 is designed just for that kind of service.[4] The model MSG90A1 has a threaded barrel designed to accept a suppressor.
