bolt carrier
A bolt is the part of a repeating, breech-loading 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 extractor and firing pin are often integral parts of the bolt.
In gas-operated firearms, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from the gas piston.
The slide of a semi-automatic pistol is a form of bolt, as it contains the same parts and serves the same functions.
Handguard sold. Adams Arms piston kit with front rail block, mid length short strike piston rod with Adam's Arms bolt Carrier (no bolt). This is a .750 gas block diameter. $80 $70 for the piston kit, rod, and carrier. Pickup in Puyallup or Sumner. Will ship for $20.

I got a little too optimistic with the number of SBR builds I was going to finish, so I'm letting go of some parts that I'm not using. Was going to build 7 SBR's so I bought 7 sets of these parts, and will probably let go of 3-4 of each. These are BRAND NEW and UNOPENED. Not "open box" or...

Looking for a used/cheap AR-15 Bolt Carrier. I have a Magpul BEV Block that I use for gun building. I get annoyed having to disassemble one of my BCGs to anchor the upper so I was hoping to pick up a beat-up old one that someone doesn't really want or need just to use as an insert. I can get a...

I bought the non-hard chrome version of one of these a few years back and wasn't impressed by Wilson's much touted and vaunted quality. The unit worked fine, but it had machining marks as if they didn't finish it or it was someones first day on the job...
