WARNING: Always ensure that the safety is fully engaged until ready to fire. A sa- fety is fully engaged only when the safety 'off' red marking (ring) is completely covered and when the safety can move no further into the safe position. The commandments of gun safety 1) Treat every gun with respect and caution. 2) Keep your eyes on the muzzle. Keep the safety on until ready to shoot.

Remington launched their iconic Model 1100 shotgun in 1963 – sparking a strong spirit of competition in Beretta, who determined to win some of their previous glory back. Two years later Beretta introduced the A300, the first of a collection of guns that continued to raise the bar and improve as the years rolled. Beretta carried on producing the popular A300 until the late 1970s, when the. Welcome to the Beretta Gun Parts section of Midwestgunworks.com. We carry parts for current production and post production Beretta firearms. Parts are available to the public for self installation, but can also be installed by our highly trained gunsmiths.

3) Unload guns when not in use; keep the actions open. 4) Be sure the barrel is clear of obstructions. 5) Be certain of the target at which you are going to fire. Know how to recognise the game you are hunting. 6) Never shoot at a flat surface or water. 7) Never climb a tree or fence or jump a ditch with a loaded gun.

Don't take a gun by the barrel. 8) Never point a gun at anything you don't want to shoot. Avoid all horseplay while handling a gun. 9) Store guns and ammunition separately, beyond the reach of children. Guns should always be unloaded. 10) Avoid alcoholic beverages before or during shooting. Shooting glasses and earplugs: shooting glasses are a must; chances of gas.

Gunpowder and dirt particle blow-back are remote but to exist. Earplugs reduce the chance of temporary or permanent loss of hearing when shooting.

Warning As the interchangeable barrel of the automatic has a different serial number to that stamped on the receiver, it may be necessary, when referring to the gun, to specify also the serial number of the barrel/s. 14 CONTENTS Page DESCRIPTION 16 a.

Mobilchokes® 22 n. Drop Adjustement 23 15 DESCRIPTION The Beretta A 303 gas-operated automatic shotgun introduces some engineering and functional novelties: - The cut-off push button (optional device) is now placed in the lower part of the fore-end thus allowing an easier insertion and disconnection.The interchangeable choke (A 303 Mobilchoke' version) is now screwed directly inside the barrel: the traditional line of the gun is not altered and the choke to tube alignment is remarkably accurate.

The newly designed receiver shows a simple decoration and a new shape: the lower corners are now chamfered to allow an easier movement of index finger towards the trigger. The trigger guard is enlarged for a better look and a more practical winter use of the gun.

Stock and fore-end have been redesigned. The new A 303 automatic maintains all the basic mechanical characteristics of the A 302 model and the interchangeability of barrels with those of the previous models. The features and the advantages which have made the Beretta automatics famous all over the world are:. The possibility of utilizing Standard chamber (2 3/4 in.) barrels or Magnum chamber (3 in.) barrels on the same receiver. Rapidly interchangeable barrels to allow a large variety of barrel lenghts and chokes. The possibility of firing cartridges which range from minimum pressures up to 700 kg/cm 2, without any kind of adjustement. The very high accuracy and stability during fire ensured by a fixed barrel.

Extremely low recoil. Absence of vibration during firing due to the presence of the recoil spring inside the stock.

Reliable and safe cocking and firing mechanism. A special locking mechanism to ensure that the gun can fire only with the bolt completely engaged in the barrel. High durability of all components in contact with combustion gasses being made of either stainless or special steel. Easily adjustable stock drop.

Easy field stripping for cleaning and inspection. Easy loading and unloading of magazine. Packing The Beretta series A 303 automatic shotguns are shipped from the factory with barrel taken down from the stock receiver fore-end assembly.

It is not advisable to carry out any further disassembly of the shotgun. If any should be necessary it should be entrusted to a competent gunsmith. Cleaning and oiling BARREL - After some use carefully clean the inside of the barrel by passing a soft cloth (flannel) through the barrel in order to remove combustion residues.

Pass another clean soft cloth through the barrel. Oil it lightly by passing a clean soft cloth soaked with Beretta oil or an equivalent through the barrel. GAS CYLINDER - PISTON WITH BUSH - MAGAZINE TUBE CAP SHAFT - At the end of the hunting season and always before storing the gun for a 20 quite long time, it is necessary to clean carefully the above mentioned parts, spraying them liberally with Beretta detergent or an equivalent. Give the detergent a few minutes to take effect, remove then the detergent and all the combustion gas residues with a phosphorous bronze brush and with a cloth soaked with detergent. Dry the parts carefully with a soft cloth. N.B.: There is no need to oil these parts. BREECH BOLT - Every 500/800 shots clean the component parts carefully with a small brush and Beretta detergent or an equivalent.

Dry carefully with a soft cloth and lightly oil the parts with Beretta oil or an equivalent. TRIGGER PLATE - Follow instructions as given for the breech bolt. INSIDE OF RECEIVER - Follow the same instructions as given for cleaning the breech bolt. Lightly oil the bolt slideways with Beretta oil or an equivalent. OUTSIDE OF MAGAZINE TUBE - Clean using Beretta detergent or an equivalent and soft cloth. Lightly oil the tube with Beretta oil or an equivalent.

Magazine capacity The capacity of the A303 magazine tube (which hold three shells) is limited, in observance of the hunting regulations in force both in Italy and other countries, to two shells by a shortening device called a reducer. This reducer limits the use of the A303 to three shells (two in the magazine and one in the chamber). Beretta includes the reducer in the A303 directly in the factory.

In some areas only hunting with shotguns with a capacity of two shells is permitted. To be able to use the A303 in such areas it is necessary to limit the capacity of the magazine tube to just one shell. Such an operation should only be carried out by a competent gunsmith.

Beretta A303 Parts

For use in countries where hunting with shotguns with a capacity of more than three shells is permitted, it is possible to increase the magazine tube capacity to three shells. Again this operation should be entrusted to a competent gunsmith.

To reduce the capacity of the magazine tube: i1. Unscrew (anticlockwise) the magazine tube cap with its shaft, at first keeping pressed in with a sharp point the head of the locking spring of the cap itself (ill. N.B.: Pay attention with the magazine spring which will be compressed (it rests against the reducer, coloured yellow).

Insert the second reducer into the first (the solid part into the hollow part) (ill. Screw (clockwise) the magazine tube cap onto the magazine tube, making sure that the head of the locking spring is inserted into the right hole, that is, blocking the cap. In order to increase the capacity of the magazine to three shells, simply take out the reducer/s. Reassembly TRIGGER PLATE 11. Carry out in reverse order the instructions given in point g13, making sure that the hammer is cocked and the carrier stop push-button is pressed in. Insert the trigger plate retaining pin taking care that the hole of the trigger plate is perfectly aligned with that of the receiver. BREECH BOLT 13.

Reassemble the breech bolt assembly by fixing the breech bolt slide with connecting rod to the breech bolt body (ill. Insert the rear of the operating rod into its slot on the breech bolt (ill. Press in the carrier stop push-button (if not already pressed). Holding the receiver on a flat surface with the ejection port facing upwards, slide the operating rod sleeve onto the magazine tube and partially insert the breech bolt assembly into the receiver (ill. Holding the stock-receiver assembly absolutely vertical, slide the operating rod sleeve downwards compressing the recoil spring, until the breech bolt remains fixed in an open position (ill. N.B.: If the operation, described in point 17, is to be carried out with ease the head of the breech bolt connecting rod must slide into its recoil spring guide slot. This will occur only if the rod is exactly coaxial to the breech bolt assembly and centered properly in the cocking handle slideway.

Insert the cocking handle in the breech bolt. Follow the instructions given in points c6, c7. C8, c9, c10, c11.

Mobilchokes' (A 303 Mobiichoke.) REPLACEMENT, CLEANING ml, Unscrew the choke anticlockwise, using the multiple spanner included (ill. Clean perfectly the choke chamber.

If necessary, use Beretta detergent and a brush. Dry carefully with a soft cloth. Should, after long use, the internal screw thread need to be cleaned, carefully screw inside the barrel the threaded head of the multiple spanner supplied, paying special attention not to damage the barrel thread. Fit the desired choke in the barrel, checking it is perfectly clean. Screw on clockwise the choke and tighten it to the end with the multiple spanner. N.B.: Check while hunting wheter the choke has in any way become loose.

Should this happen, the choke must be tightened to the end again. Be sure, before operating that barrel chamber and magazine are empty. WARNING: Remember that the use of the barrel without choke inserted is not allowed. Should this happen, the internal screw thread could be damaged.
