An L85A2 rifle with a partially-shrouded barrel A Winchester Model 12 combat shotgun with a barrel shroud and attached bayonet. A barrel shroud is an external covering that envelops (either partially or full-length) the barrel of a firearm to prevent unwanted direct contact with the barrel (e.g. accidental collision with surrounding objects or ...
A bolt-on thermal sleeve. A thermal sleeve, or blanket, is a device around the length of a gun barrel of a large caliber gun, typically found on modern tanks.Its primary purpose is to provide a more consistent temperature to the gun barrel, preventing distortions due to differential thermal expansion caused by the temperature differences around the barrel when firing.
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1]
A muzzle shroud differs from a silencer (sound suppressor) in that its primary function is not to suppress the sound, but merely redirect it so to increase the comfort of the shooter, reducing the concussion to a comfortable level. [4] Linear compensators are also a form of muzzle shrouds.
With a Walnut stock and rocker-type thumb safety, this airgun is a great collector's rifle, known for its accuracy. As previously noted, in 1977 Sheridan Products Inc. was acquired by the Benjamin Air Rifle Co., also ending line of original Sheridan Model F's in 1976. For help in dating your model, find the serial number on the barrel.
The duct or shroud is an aerodynamic ring which surrounds the fan and closely fits the blade tips. It must be made rigid enough not to distort under flight loads nor touch the blades as they turn. The duct performs several functions: Principally, it reduces the vortices created by air flowing round the ends of the blades.
Bedding epoxy in a stock. Rifle bedding is a gunsmithing process of providing a rigid and consistent foundation for a rifle’s operational components, by creating a stable and close-fitting bearing surface between the gun's functional parts (i.e. the receiver housing the barrelled action) and its structural support (i.e. the stock) that do not deform with heat, pressure and moisture, or shift ...
The BSA Supersport is an air rifle produced by BSA Guns (UK) Limited a subsidiary of Spanish manufacturer Gamo and was first introduced in 1986. [1] It is essentially the same rifle as the Lightning, the only difference being that the Lightning has the BSA Volumetric Silencer fitted. It is made in three calibres, 0.177 in (4.5 mm), 0.22 in (5.6 ...
