A telescoping bolt is a bolt that wraps around the breech end of the barrel. This bolt design is often used to reduce overall weapon length without sacrificing barrel length or bolt weight. A turn bolt refers to a firearm component where the whole bolt without using a bolt carrier turns to lock and unlock.
short-stroke gas piston Short stroke gas piston and bolt carrier group, from a gas piston AR-15. With a short-stroke or tappet system, the piston moves separately from the bolt group. It may directly push [12] the bolt group parts, as in the M1 carbine, or operate through a connecting rod or assembly, as in the Armalite AR-18 or the SKS.

The carrier causes an internal component of the bolt carrier group named the lifter to push the bearings outward. The Lifter has angled grooves that interact with the bearings. [ 32 ] Bearing delay is designed to be tuned based on the user's preference or configuration of other components by swapping to a lifter with a different geometry.

A carrier strike group (CSG) is a type of carrier battle group of the United States Navy. [1] It is an operational formation composed of roughly 7,500 personnel, usually an aircraft carrier , at least one cruiser , a destroyer squadron of at least two destroyers or frigates , [ 2 ] and a carrier air wing of 65 to 70 aircraft.
When first introduced in 1956, the AR-10 used an innovative combination of a straight-line barrel/stock design with phenolic composite, a new patent-filed gas-operated bolt and carrier system and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over 1 lb (0.45 kg) lighter than other infantry ...
Carrier tilt is a wear issue that can arise in some gas piston-based firearm operating systems. High pressure gas pushes the gas piston back hitting the bolt carrier. This force pushes the bolt carrier down into the buffer tube wall. This can lead to increased wear, shaved and/or chipped metal. This in turn can lead to a loss of accuracy. [1]
