- CompatibilityUpper vs Lower Receiver (3D)Take a real AR-15 apart in 3D and see how the upper and lower receiver go together. Push the takedown pin, hinge the upper open on the pivot pin, pull the bolt carrier group and lift the upper off, with every part colored by the half it belongs to.
- CompatibilityHow Muzzle Devices Work (3D)Watch one shot leave an AR-15 muzzle in slow motion 3D through a bare barrel, a flash hider, a compensator, a muzzle brake and a linear comp. See where each sends the gas, and what that does to flash, recoil, muzzle rise and the blast beside you.
