The Definition of Sleeved Barrels
An economical method of bringing new life to a damaged pair of barrels, regardless of their original method of jointing.
The ribs are removed. The barrels are cut off 3" - 4" from the breech end and discarded. The bores of the remaining breech-end are reamed out oversize.
New tubes are fitted down into the original breech section and filed down to fit flush. The original ribs are then replaced. Sleeving is considerably less expensive than building a completely new set of barrels. Much of the time required to build a set of barrels is concentrated in the fitting of the breech end to the receiver; this work is salvaged through sleeving. Sleeving can be recognized by a pair of circumferential lines around the barrels a few inches from the breech; the more invisible, the finer the job. A sleeved gun should always be identified as such amongst the proof marks, and if done in England must be properly reproofed. Photo
Sleeving is not the same thing as Monoblocking.
19 Other Firearms Definitions You Need To Know
The interval of time between trigger release and the detonation of the primer. Generally, the faster the lock time the better, because this makes it easier to shoot accurately.
The process of a bullet expanding under pressure to fit the bore of the firearm, or a cartridge case expanding under pressure to seal the chamber.
A charge of powder, a projectile or a cartridge. Also, to prepare a gun for firing by inserting ammunition into it.
The part of a revolver that holds cartridges in
separate chambers radially around a central hingepin. The cylinder revolves as
the handgun is cocked, , either to the left or to the right depending on the gun maker's design,
bringing each successive cartridge into position, and
locked into alignment with the barrel for firing.
The National Association for Gun Rights (NAGR) is a gun rights advocacy group in the United States. Headed by Dudley Brown, a long-time gun rights advocate, the National Association for Gun Rights was formed
in 2000 as a grassroots, member-centric organization with a no-compromise approach to gun rights issues through an aggressive strategy.
A trigger that can be easily adjusted by the user. Adjustable triggers are common on specialized target-shooting firearms.
A set of holes in a target left by a succession of bullets fired from the same rifle or handgun,
using the same ammunition and sight setting. Fired (within the limits of one's marksmanship ability)
to determine the inherent accuracy of the rifle/ammunition combination,
and to aid in the proper adjustment of the sights.
The accumulation of unwanted material on solid surfaces. The fouling material can consist of either powder, lubrication residue, or bullet material such as lead or copper.
Defined according to Section 921 (a) (16), Title 18, U.S.C. as:
A. any firearm (including any firearm with matchlock, flintlock, percussion cap, or similar type of ignition system) manufactured in or before 1898; and
B. any replica of any firearm described in subparagraph (A) if such replica (i) is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition, or (ii)
uses rimfire or conventional centerfire fixed ammunition which is no longer manufactured in the United States and which is not readily available in the ordinary channels of commercial trade.
More commonly known as WSM, it is a family of centerfire cartridges designed by Winchester Repeating Arms Company
A type of small arms ammunition that eliminates the cartridge case that typically holds the primer, propellant, and projectile together as a unit.
The earliest type of gun, now also popular as modern-made replicas, in which blackpowder and projectile(s) are
separately loaded in through the muzzle. The term is often applied to cap-and-ball revolvers where the loading is
done not actually through the muzzle but through the open ends of the cylinder's chambers.
Pulling the slide back to its rearmost position, and then letting it go forward under its own spring tension.
Racking the slide loads the chamber and prepares the gun to fire in a semi-automatic handgun.
A shotgun barrel that has a bore diameter increased beyond standard specifications, but less than the SAAMI maximum.
Done in an attempt to reduce felt recoil, improve patterning, or change the balance of the shotgun.
Violent Crime Control and Law Enforcement Act of 1994.
It is an act of Congress dealing with crime and law enforcement that became law in 1994.
Of the sections of the bill, it included the Federal Assault Weapons Ban.
A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired.
In such case the breechblock immediately begins to separate from the barrel upon firing.
Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber,
are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.
A small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge.
To jerk a firearm off target inadvertently in the instant of firing in timid anticipation of recoil. Commonly caused by learning to shoot with a gun more powerful then they are ready for.
