bolt carrier group
A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms "breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section.
In most automatic firearms that use delayed blowback, recoil or gas operation, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from a gas tube (direct impingement) or a piston system.
The slide of a self-loading pistol can be considered a bolt carrier, as it contains the same components and serves the same functions.
Larue BCG I picked up as a spare when I bought an UU kit. Ran it for about 140 rounds, cleaned it and put it back in the packaging.
Minor wear marks but functions flawlessly.
$150 *SPF
