INTRODUCTION

The Browning automatic rifle was originally designedby John Browning in 1917, to meet th e requirements of th eAmerican Army during th e 1914-1918 war. For this purposeit was mass-produced by th e Colt Company in America,and used by th e U. S. Armed Forces during the first worldwa r an d also in th e second.

John M. Browning ha d for several years worked inLiege in close collaboration with Fabrique Nationaled'Armes de Guerre, and during this time had perfectedmany inventions. It was, therefore, natural that th eBrowning automatic machine rifle patents should beentrusted to them for manufacture.During the period between the two wars F. N. in troduced several modifications an d improvements. Theseculminated in th e Type 3o , made to the requirementsof th e Belgian Government, and incorporated a gas regulator an d a slowing-up device to be used to reduce therate of fire, when required.Fabrique Nationale have now pu t on th e market th epresent Model 'D ', which embodies the experience gainedduring the last war, and the technical advantages ofmodern steels an d methods of production . The mainfeatures of th e original design are still maintained, bu t inth e ne w model th e barrel has been made removable, an dit is possible to take out the breech-block mechanismwithout complete stripping.- -- --- 3

Its light weight, accuracy and speed into action,combined with its robustness an d simplicity, make th eBrowning automatic machine rifle suitable for use in th efield both as an automatic rifle an d as a light machine gun.

GENERAL CHARACTERISTICSMethod of operation. - The breech mechanism is automatically opened by means of ga s operating throughth e gas cylinder on a piston. The closing of th ebreech is done by means of th e usual return springs.During th e actual firing of th e cartridge the breechblock is positively locked, bu t remains held in therear position after the opening operation has beenperformed.Detachable barrel. - This is held in the receiver by adifferential nut , which takes up an y play or clearancebetween the barrel an d receiver. The barrel is aircooled by flanges, an d is equipped with a handlefor transport or dismounting of th e barrel.Method of feed. - Th e method of feed is by means of a20-round magazine positioned in the underside ofth e receiver. This position reduces visibility to anenemy, and magazines ca n be changed without th efirer betraying his position.Rates of fire. - The normal rate of fire is 600 rounds pe rminute, bu t a specially designed slowing-up device,which is incorporated in the trigger guard, enablesthis rate to be reduced to 350 rounds pe r minute.Stripping. - Stripp-ing. is possible in two . stages. In th efirst place the breech -block can be quickly removedby th e firer, whilst still in th e firing position, for th epurpose of replacing a firing pi n or extractor.Complete stripping of th e mechanism ca n be donein the same position by hinging the butt downwards

to form a support, leaving both hands free to handleth e mechanism .Safety. - Every care has been taken to ensure safety underal l conditions. In addition to th e normal mechanicalsafeties, th e breech-block is also positively locked atth e moment of firing, which cannot occur prematurely . The mechanism being held in th e rear position- -- --- 7

after a round ha s been fired enables the chamber tocool more quickly, and there is no danger from acartridge being left in a hot barrel.Suppleness. - The Browning automatic rifle has a remarkable suppleness of action because the opening

of th e bolt is progressive by means of cams. Theextraction of th e case does not occur by a straightpull bu t by soft primary extraction. This avoidshardship of th e mechanism an d allows a goodfunctioning without cleaning no r oiling event withammunition which are no t perfect. It is on e ofth e reasons why the gun is able to function withoutbreakages or stoppages of

The barrel (1) is provided at th e front by a foresightbe d (3) which is supporting the foresight blade (2). It hasalso a ga s cylinder bracket (201) which is a housing for th eregulator (250-256).The lower wall of th e barrel has a hole in the ga scylinder bracket. It is through this hole that th e ga s isblown into th e ga s cylinder.At th e rear en d th e barrel has a handle (1a) connectedwith the locking nu t (lb) which has an external and inter-nal differential thread. The internal thread engages thebarrel, the external thread engages the receiver.By swinging the handle, it is thus possible, fo r th edifferential thread, to tighten the barrel on the receiverso as to avoid an y clearance which is automaticallyabsorbed .By pulling the handle, in th e same wa y as if on ewished to separate it from th e barrel, it is loosened fromthe notch in the locking nut and the handle is no moreconnected to th e nut and can swing freely. It may thenbe used as a handle to carry the gu n .The muzzle of th e barrel has a thread which may beused to screw th e muzzle ring (136) th e flash hider (133)or th e blank firing device (503).12- -- ---

Th e rear of th e barrel has a recess for th e extractor (45 )an d a ramp guiding the cartridges in th e chamber.The barrel has flanges to increase ai r cooling.The regulator is of the exhaust type . In th e unscrewedposition it enables most of th e gas to escape outside whileonly a small part of it is allowed to penetrate into th e gascylinder. In the screwed position, most of th e gas goesstraight in th e ga s cylinder.This ha s th e advantage to allow just th e quantity ofrequired to operate th e gu n to come into th e mecha-nism .

FUNCTIONING

FORWARD MOVEMENTThe gu n being cocked1 when the trigger (210) is pulled 1th e slide (205) is released by th e right sear (213) an d th emechanism is pushed forward by th e recoil springs (97E 1971) . The bottom of the bolt (40) strikes th e upper partof th e first cartridge and pushes it into the chamber. Thebase of th e cartridge case slides up th e front face of th ebolt (40) behind th e extractor (45). When th e lower camsurface of th e breech-block (41) strikes th e en d of th e boltsupports (11 1 12) the breech-block ro.i:;as up . Th e bolt (40)stops against the rear face of th e barrel. Th e breech-block(41) pushed upward through the link (43) by th e slide (205) 1

which moves forward 1 comes in th e locking recess of th ereceiver (8). The breech-block leaning against th e lockingface of th e receiver completely locks th e gun. The slide(205) continues forward with the hammer (48) which strikesth e firing pi n (47) an d fires th e primer of th e cartridge.The forward movement of th e slide is stopped when itsshoulder strikes th e rear part of th e gas cylinder (247).

BACKWARD MOVEMENTAfter th e shot ha s been fired 1 when the bullet passesth e ga s opening in the barrel 1 a part of th e expandingpowder gases passes through the opening into th e ga scylinder (247) an d pushes to th e rear th e piston (204) an dth e slide (205). The slide (205L through th e link (43) pullsdown the breech-block (41) an d unlocks th e gun. Thebolt (40) starts very slowly backwards/ gaining speed asth e breech-block (41) nears its completely unlocked posi

tion. When this point is reached the bolt (40) an d breechblock (41) travel at th e same speed as th e slide (205). Thewithdrawal of th e firing pi n (47) results from th e actionof the slope cut in the breech-block (41) on the firing pi nheel. The empty case is drawn from the chamber by th eextractor (45) an d is held against th e front face of the bolt(40) until it strikes th e ejector (241) which throws it ou t toth e right through the ejection opening .28- -- ---

Th e backward movement limited to th e rear by th ebuffer (102) produces the compression of th e return springs(97E 1 971) . The opening movement being complete 1 th eslide (205) an d the whole firing mechanism is held to th erear as th e slide (205) is hooked by th e right sear (213).A remarkable feature of th e Browning automatic rifleis the extreme softness with which the case is drawn outof th e chamber. At the beginning of the opening move ment when the breech-block reaches its low position 1 itis slightly pushed backward by a progressive movementwhen its ca m comes in contact with th e rear parts of th ebolt guides (11 1 12) . That slight movement to th e rearloosens th e case from the chamber before it is carried ou tby direct pull. Extraction occurs thus by a double movement : first loosen th e ca se from tl;le chamber1 then pullou t by direct pull. That is on e of th e reasons why th e

gu n is able to function correctly even with irregularammunition.AUTOMATIC FIRING AT FULL RATE

Cock th e gu n an d se t change lever (219) in position'" M ''. Pull th e trigger. Firing will be going on at fullrate until th e pull on the trigger is released . With changelever (219) in th e M '' position . the left sear (216) is switchedoff an d does no t interfere with the movement of the slide(205) . The slowing-up device has consequently no actionon the mechanism.

AUTOMATIC FIRING AT SLOW RATECock the gun and se t change lever (219) in position

R . The slide is kept in th e rear position by th e rightsear (213) which is a little longer than the left sear (216).By pulling th e trigger (210) th e sear (213) releases th e slide(205). The slide (205) pushed forward by th e recoil springs(97E . 971) is retained by the second sear (216) which movesslightly forward owing the oval hole of its pi n (57) . Theleft sear drives forward th e catch (220) which releases th eslowing -up device lever (227). This lever raises up underth e action of th e spring (223). The raising movemertt ofthe lever is slowed by th e interference of th e rack (230L----29


17/34

th e pinion (231) and the ratchet (233). That slowing-upmovement constitutes th e slowing-up of th e rate of fireitself.Th e lever (227) being raised, swings up th e forwardend of th e left sear (216) an d draws down the rear en d ofth e sear. When the raising movement of th e lever (227)is completed, th e sear (216) disengages completely fromth e notch in th e slide an d th e slide is released an d pushedforward by th e return springs (97, 971) . When movingforward th e slide (205) depresses th e lever (227) which iscaught again by th e latch (220).

SINGLE SHOT FIRINGCock the gun and se t change lever (219) in pos1t10n R (same as for slow automatic firing). Release th e

trigger after each shot. The rate of fire is slow enough torelease the trigger quickly enough to prevent double shots.GAS INLET ADJUSTMENT

Th e gun being ready in firing position, the adjustmentof th e ga s inlet is made as follows:Unscrew the shroud {255) by means of th e screw (253)and the combined tool (501) until th e ga s escape holes arenearly discovered. Cock the gun and se t change lever{219) in position R . Firing shot by shot th e mechanismmust remain open after every shot, th e slide being stoppedat th e rear, an d th e ejection must be normal, i.e. the emptycases ar e projected about one an d a half yard away.If th e functioning is no t correct screw the mantle alittle more, in order to obturate a little more th e ga s escapeholes, until functioning is correct.If th e ejection is too violent unscrew the shroud untilfunctioning is as described above.

FUNCTIONING OF THE BUFFERAfter every shot, th e slide (205) is violently projectedto th e rear. That movement is slowed by th e return springs(97E, 971) through the return spring rod (50).30------

Th e slide strikes th e plug (102) which recoils an dpushes back th e first friction ring (100) an d th e first cone(101) which is pressed into th e ring an d pushes the nexton e an d so on th e last one compressing th e buffer spring(103). Th e friction rings (100) who are split, open slightlyunder action of the cones (101) and rub against th e tube(8h) containing th e buffer. The friction of th e rings (100)added to th e action of th e return springs (97, 971) an dthat of th e buffer spring (103) absorb the recoil of th emechanism.
