Finnish use: Only two prototypes chambered to 20-mm ammunition of Lahti's own design used in Winter War. The real production did not start until after Winter War. Some 1,850 manufactured during Interim Peace and Continuation War. These weapons saw large-scale use with Finnish troops during Continuation War. With large variety of ammunition they proved to be very versatile and remained useful even when their best days as antitank-weapon were gone. These new uses included bunker busting, long range sniping and use as improvised anti-aircraft weapon.
As mentioned L-39 was gas-action semiautomatic, but it was not purely semiautomatic in common sense meaning of the term. When a shot was fired and the bolt retreated back, it did not return forward for next shot until being released with bolt release switch located front section of the weapon's pistol grip. Apparently releasing the bolt could be done just immediately firing the shot as this supposedly reduced the feel of recoil. Mechanism of L-39 was cocked from the crank-like handle located in right side of the weapon. The weapon fired from a closed bolt. Presumably the bolt not returning forward had been added design to improve cooling of the weapon. As common to antitank-rifle designs of the era for obvious reasons L-39 antitank-rifle had both bipod and muzzle brake. Amount of gas getting to gas-action mechanism was adjustable (four settings: 1.5, 1.8, 2.2 and 2.5 indicate diameter of hole to gas-action mechanism). Magazines used in the gun are not exactly light either - magazine weight 3.37-kg empty and when fully loaded some 6.7-kg. Experienced gunner could achieve rate of fire as high as 15 shots/minute. The protective arch in front of the trigger guard is there for a good reason - the weapon extracts used (heavy and hot) cartridge cases downwards below the weapon just in front of the trigger guard. Sights are fully adjustable with rear sight settings from 200 to 1400 meters. Because of the magazine located on top the weapon the sights are located to left side of the weapon. Typical equipment included three or four magazine pouches or boxes each containing two magazines - in other words typically L-39 antitank-rifle was issued with 6 or 8 magazines. Once the anti-aircraft use of these weapons became common during Continuation War simple anti-aircraft mount (allowing the weapon to be attached on head of a pole pointing upwards) were manufactured and delivered for them. Before this happened some of the Finnish troops build improvised mounts suitable for this kind of use.
As mentioned only prototypes of L-39 antitank-rifle were manufactured in 20 mm x 113 B, since decision about manufacturing the gun in 20 mm x 138 B (Solothurn Long) was made before stating of first production run. 20 mm x 138 B ammunition types used with L-39 included AP, AP-T, APHE-T, HE-T and phosphorous shells. AP was most plentiful of ammunition types, but not that well suited for the purposes for which L-39 was used during the war. While Soviet medium and heavy tanks soon became just too heavily armour to be destroyed with this antitank rifle the well-aimed hits could still immobilise tank, damage rotation system of its turret or do damage to other vulnerable parts of medium and heavy tanks. At the same time AP-T and APHE-T projectiles fired by these weapons were dangerous to even well-armoured Soviet Stormovik ground attack aircraft. Well placed shots of HE and phosphorous shells could be used for taking out machinegun nests or taking out antitank-guns, infantry guns or field guns by simply shooting their gun crews through gun shield. But they could be used be fired into vision slots bunkers for great effect and were used to keep Soviet infantry "entertained" during the long trench war period. In addition summer time phosphorous shells fired with high trajectory could be used for setting forest fires behind Soviet lines. However availability of HE, APHE-tracer and phosphorous shells with L-39 was typically more limited as these ammunition types were mostly issued for antiaircraft-guns.
Finnish military received 325 anti-aircraft rifles L-39/44, all of them in year 1944, but most only after Continuation War had already ended and removed immediate need for this sort of somewhat ad hoc anti-aircraft weapon. The 325 guns included 54 L-39 antitank-rifles (of L-39 3rd production series), whose parts had already been manufactured, but had not been delivered yet and were modified in L-39/44 configuration before delivery. Another 170 weapons had originally been ordered as (4th order of) L-39 antitank-rifles, but the order was changed as L-39/44 before their manufacturing was completed. In addition November of 1944 Finnish military ordered modification work for 606 of the earlier delivered L-39 antitank-rifles into L-39/44 configuration, but apparently this order was never completed and ended up getting cancelled. The equipment delivered with each L-39/44 depended to which type of troops it was delivered - those going to Army were equipped with both anti-aircraft and antitank-equipment, while those delivered to units belonging to Air Force that lacked anti-tank equipment. As noted most L-39/44 were manufactured too late to see any action in World War 2. As with L-39 antitank-rifle to whose full-auto version L-39/44 anti-aircraft rifle basically was, the sole manufacturer of this weapon was VKT (Valtion Kivääritehdas = State Rifle Factory). Structural design of this gas-action full-automatic firing from open bolt soon proved have serious durability issued when used in full-auto configuration. The most notable structural difference in between L-39 and L-39/44 was the firing pin design - L-39/44 had a fixed firing pin. Being true open bolt firing design L-39/44 bolt stopped in its rear position only when bolt release was released. While this was not necessary the best idea for shooting accuracy, it was essential feature for the design to work in full-auto model and allowed more effective cooling. And lets face it - considering this is 20-mm automatic weapon with free traverse gun mount and fired while supported to gunner's shoulder, pin-point long-range accuracy would not have really been a realistic requirement. The anti-aircraft sights used with it were also useful only for giving a summary aiming point. The sight system had been designed to provide rough aiming points advance-wise for aircraft flying 430 km/h at distance of 1,200 meters in angle of 30 or 60 degrees. Once the gunner released the bolt firing the weapon the only real way to adjust aim was by using tracers as a reference point.
