Brocock Air Cartridges

Brocock FoxPictured above is the Brocock Fox, a novel air rifle very possibly inspired by the gun described in Frederick Forsythe’s The Day of the Jackal. There’s the skeleton design, the simple trigger, moderator, all the necessary bits for a minimal gun. But the inquisitive viewer might well ask, where’s the spring, or the air chamber, or the CO2 resevoir?

Brocock guns had none of these, owing to a very clever design – the air cartridge. This was a small reservoir that looked for all the world like a firearm cartridge, but was actually a self-contained airgun powerplant, containing pressure tank, pellet, and valve all in one package. The shooter would prepare a number of cartridges ahead of time, using a hand pump or SCUBA tank. This might be a little inconvenient for plinking, but hunters, who might only fire a dozen shots a day, found it very convenient. Given the difficulty of owning a real firearm in Great Britain, a lot of shooters were willing to put up with the inconvenience in order to shoot something that felt and functioned like a real firearm.

The Brocockcartridges functioned very much like firearms cartridges, too. Guns designed to use Brocock cartridges had a firing pin that struck a valve on the rear of the cartridge, releasing the gas and propelling the pellet forward. This design meant that not only was it simple to design guns that used the Brocock system- see the Fox above- but many firearms designs could be easily adapted to it. Brocock sold a number of very realistic handguns that were produced by European makers, including some stunning adaptations of percussion revolvers. The Brocock 6 was a standout- a Weirauch-made revolver that was essentially their .357 revolver with a different cylinder and a .22 caliber barrel. It looked and functioned just like its firearm cousin.

And that is what eventually led to the downfall of the Brocock system. The top-end guns were so like firearms that they could very simply be turned into firearms. A few gunsmiths made adapters on their lathes that allowed .22 cartridges and even .38 cartridges to be fired in Brocock pistols and rifles. This led to the banning of all cartridge air gun in 2004, and the surrender of all Brocock guns and cartridges to the police. (Today, firearms possession is essentially outlawed in Great Britain- even the British Olympic pistol teams has to practice abroad- but gun crime continues to increase.)

If you do find a Brocock gun or cartridge, hang on to it, as they’re becoming very desirable collectibles. Cartridge replacement and maintenance could be an issue, of course. I haven’t heard of anyone in this country making replacement cartridges, but I suppose it’s only a matter of time before some clever airgunsmith decides to service the Brococks still being shot here and in other countries.

    Actually the guns were not banned. You just had to put them on a firearms certificate, which was granted without a problem! I have a fox and a pair of uberti pistols which are both priceless and worthless, as they cannot be sold to anybody!

    You say that all Brocock guns were handed into the police. This is untrue as about 80% are now unacounted for. This is good news. This serves the police right for demanding such a futile law in the first place.

    “If you do find a Brocock gun or cartridge, hang on to it”

    I wouldn’t advise that if you live in the UK. Its now a mandatory 5 year prison sentence if caught. Best to hand it in if you find one really

    Hello Sandy, to remove the cylinder, it must relax the screw, to do it, it must immobilize the same of the right part of the weapon, and, to unscrew the left side. EYE! when they leave the two parts the screw, it does not lose the small wharf, without him, will not be able to return to mount the weapon. Once removed the screw, it throws strong of axis, it removes it and it tries to remove the cylinder; if one moves but it does not leave, then it must oscillate the cylinder towards the left and to the right alternatively, that, it would be enough so that the pellet, good I imagine that habra like minimum one and between two and three within the barrel, leave without problems.

    First offence not five years.UK prisons now are over filled thanks to the london riots.
    You would get the gun taken away from you if caught then it probably be sold abroad for the inland revenue.But then again a lot people didn’t know the law had changed on a sub 6ft-lb air pistol!

    Hi, I have a small Collection of Brocock guns. The prime being a 5,5″ 1873 Navy Colt from Uberti. Besides guns I have two slim Jim pumps, one RAM charger for filling from bottle and 80 cartridges.
    Due to the Danish government making all airguns with bore caliber larger than .177 equal to firearms. (FAC controlled) I have decided to sell all, if I can find the rigtht buyer, and we can handle it fully legally with respect for the different countrys gunlaws. (Even though they are queer). If interested I can mail you directly.
