What Are the 3 Major Parts of a Gun?
The basic parts of all modern firearms are:
- Barrel - The tube that the projectile travels down.
- Action - The part of the gun that discharges the projectile by striking the primer.
- Stock - Used by the shooter to hold the firearm, and usually at least some part of the frame to support and connect the action and the barrel.
Can You Buy All the Parts to Build a Gun Online?
You cannot buy the receiver online (lower receiver for AR-pattern and similar guns), as that is the part that is serialized and defined by the ATF as a firearm. All the other parts can be purchased online at OpticsPlanet where allowed by law.
