That's right, hasn't been milled. ( Log Out / Commercially the HK33 was a successful design but it did not sell as well as the G3. Like its older brother, the G3, the HK33 comes in various configurations. The HK33 series of rifles were adopted by the Brazilian Air Force (Força Aérea Brasileira or FAB), the armed forces of Thailand and Malaysia where they were produced under a licence agreement. The short barrel does, however, result in a reduced muzzle velocity and therefore a shorter effective range when compared with the HK33. Heckler & Koch would submit their designs through Harrington & Richardson and their contacts rather than set up an American branch.
The rifle was also licence-built in Turkey by MKEK, and exported from France branded as MAS but actually made in Germany. 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). 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 weapon weighed just over 3kg (7lb), almost a 1 kg less than its parent rifle the HK33. Unlike the HK33, the HK53 has a four prong flash hider. Included with the rifle are a detachable bipod, bayonet (from the G3), sling, cleaning kit and a magazine loader. Upon firing, the two cylindrical rollers in the bolt head are cammed inward by inclined surfaces of the barrel extension and impart a rearward motion on the locking piece, which also propels the bolt carrier rearward. Chambered in 5.56mm x 45mm NATO, the HK53 packs a substantially heavier punch than the 9mm MP5 without being much bigger.

Johnston & T.B. Turkish MKEK-made rifles are issued with 30-round polymer magazines. The ejector lever was installed in the trigger housing and is actuated by the recoiling bolt. The basic operating systems of the HK33 are the same as those of the G3. The Fero elevation knob features Bullet Drop Compensation (BDC) settings for 100–600 metres (109–656 yd) in 100 metres (109 yd) increments calibrated for 5.56×45mm NATO ball ammunition.[3]. [15] The Kurdistan Workers' Party often claimed it seized HK33s from the Turkish forces.[16].
Calibre: 5.56x45mm This deliberately prevents non-armorers to (re)zero the iron sight line. Although heavier than the M16, it was used in small numbers by SEAL teams due to its available 40-round magazine. Action: Roller delayed blowback The V-notch and apertures are calibrated for 5.56×45mm NATO ball ammunition. 30-round arch magazines were also introduced for use with the rifle. New content will be added above the current area of focus upon selection During its service life the HK53 went through a series of changes to furniture mouldings, buttstock types and fire selector options. Some Army Air Corps helicopter pilots carried a HK53 as their personal weapon while flying sorties in Northern Ireland. The HK53 was also used by 14 Int (or 'Det') operators during The Troubles. With the right clothing, the HK53A3 could be carried as a concealed weapon. ( Log Out / Change ), You are commenting using your Twitter account.

- TACTICAL LIFE GEAR, Heckler & Koch HK33 – The Armourers Bench. During its production life the rifle has received several minor improvements (these modified weapons are sometimes referred to collectively as the HK33E). My dealer said that the earlier guns were marked HK33 but this one is an IC date code and my IB rifle is marked HK93 and has a semi auto carrier. Like the HK33, the HK53 fed from 25, 30 or 40 round box magazines. The barrel contains 6 right-hand grooves and terminates with a slotted flash suppressor that enables the use of rifle grenades and supports a standard G3-type bayonet that mounts above the barrel. Unlike the HK33, the HK53 had a four-prong flash-hider. However, few major contracts were forthcoming with the German military opting to continue using the 7.62x51mm G3. The G3 roller-delayed blowback mechanism designed around 7.62×51mm NATO ammunition was downsized and revised for reliably using 5.56×45mm NATO ammunition. The Bolt carrier also screams HK33 as it is date coded to the rifle but it is a full auto carrier. A number of police forces and militaries adopted the HK53 for a variety of roles. Designated the HK53 MICV in this role the foregrip and stock was removed and a specially designed endcap and a spent case bag could be attachment. The weapon weighed just over 3kg (7lb), almost a 1 kg less than its parent rifle the HK33. As shown in various MoD Equipment Failure Reports dating from the early 1990s the HK53’s in British service suffered from repeated damage and failure of the carbines’ locking rollers. The Royal Military Police Close Protection Unit’s L101A1’s were also fitted with a new two stage buffer within a fixed stock.
We set ourselves apart by supplying unique parts at a good value and standing by our products by offering outstanding customer service. The HK13/HK23/HK33/HK53 series was offered to Harrington & Richardson in 1964. Change ), You are commenting using your Facebook account. Several police forces and militaries adopted the HK53. A close protection (CP) specialist with Royal Marine Police Troop (left) armed with a HK53A3, Iraq, 2003. This ratio is continued until the locking rollers have been withdrawn from the barrel extension recesses. It is recommended that all parts be fit by a qualified gunsmith. The Bolt carrier also screams HK33 as it is date coded to the rifle but it is a full auto carrier. The lever essentially ratchets into place with friction, providing enough resistance to being re-opened that the bolt carrier does not rebound. Chambered in 5.56mm x 45mm NATO, the HK53 packs a substantially heavier punch than the 9mm MP5 without being much bigger. It remained in production into the early 2000s, when Heckler & Koch replaced the HK33 and HK53 with the G36 and G36K. The Hensoldt Fero 4×24 telescopic sight and mount assembly were developed for designated marksman use.
Like the HK33, the HK53 fed from 25, 30 or 40 round box magazines.
H&K offers several different trigger assemblies: a three-shot burst fire control group with selector lever/safety (selector settings: "0" weapon is safe, "1" single fire, "2" 2-round burst or "3" 3-round burst; the selector lever is ambidextrous); a "Navy" trigger unit (three settings: safe, semi and full auto fire) and a four-position trigger group (selector settings: safe, single fire, 3-round burst and automatic fire). Length (with stock extended): 76.5cm (30in) Like the HK33, the HK53 fed from 25-, 30- or 40-round box magazines.
My dealer said that the earlier guns were marked HK33 but this one is an IC date code and my IB rifle is marked HK93 and has a semi auto carrier. The HK33 is a 5.56mm assault rifle developed in the 1960s by West German armament manufacturer Heckler & Koch GmbH (H&K), primarily for export. The firearm is equipped with a relatively low iron sight line that consists of a Drehvisier a rotary rear drum and hooded front post. In the mid-1970s H&K began development an even shorter version. The weapon weighed 6.6 pounds, around two pounds less than its parent rifle the HK33. This built-in mechanical disadvantage delays the movement of the bolt head relative to the bolt head carrier which is withdrawing at significant higher velocity of the bolt head. Due to the modularity of the HK33′s design users could replace the butt of the standard rifle with a collapsible telescopic metal stock. Its butt-stock, fore-stock and pistol-grip/fire-control assembly may be changed at will in a variety of configurations (listed below). getting in and out of vehicles or inside buildings.

Special forces units around the world including the British SAS, Royal Military Police Close Protection Unit and Royal Marines, designated the L101A1 in British service, who typically used it during close protection duties and operations involving close quarter battle. The HK53a3 makes for a good weapon for CP duty. We specialize in all military surplus weapons from AK-47s, AR-15s, Mausers, CETME, Enfields, UZIs, and much more! The HK53 is essentially a cut-down HK33. The HK33 is a modular weapon system. In 1968 Heckler & Koch launched the HK33, chambered in 5.56x45mm, to compete with Colt’s AR-15/M16. Additionally, the HK33 can be used to mount a 40 mm under-barrel HK79 grenade launcher or a blank-firing adaptor. Weight (collapsible stock, unloaded): 3.35kg (7.4lb) The chamber is opened under high pressure, thus the chamber received a series of flutes in order to increase extraction reliability and prevent sticking of the spent casing to the chamber walls. The rifle is disassembled into the following components for maintenance: the receiver/barrel, stock with return spring, bolt assembly and trigger pack in pistol grip. The rear sight is mechanically adjustable for both windage and elevation with the help of tools. The rotary drum features an open V-notch (numbered 1) for rapid target acquisition, close range, low light and impaired visibility use and three apertures (numbered 2, 3 and 4) used for: 200–400 metres (219–437 yd) in 100 metres (109 yd) increments for more precise aiming. The HK33, and later HK53, used the same roller-delayed blowback action developed for the G3 in the mid 1950s.
