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.
In the United States, the ATF has ruled that since the sound waves are not dampened and are metered at the same levels at two measuring points (1 m (3.3 ft) to the left and 0 m in front of the muzzle and 1 m (3.3 ft) left and 5 m (16 ft) forward of the muzzle) this is not a sound suppressing device.
Weihrauch then produced an under-lever spring piston rifle, the HW77. This gun opened fully for loading directly into the breech of the barrel, like a Feinwerkbau match rifle. This was a great improvement over under lever air rifles which utilized a loading tap from which the pellet had to leap into the barrel.

The AKM rifle's slant-cut compensator . Construction of a muzzle brake or compensator can be as simple as a diagonal cut at the muzzle end of the barrel to direct some of the escaping gas upward. On the AKM assault rifle, the brake also angles slightly to the right to counteract the sideways movement of the rifle under recoil.
