Lantac Ultimate Forward Assist

The Lantac Ultimate Forward Assist (brand part number 01-UP-UFA-S) is a direct-fit replacement forward assist assembly for AR-15 upper receivers. Lantac builds it to drop into any mil-spec AR-15 upper in place of the factory forward assist, giving the shooter a positive way to seat the bolt carrier group fully into battery if it hangs up on a dirty or dry chamber. Because it’s a direct-fit part, it installs with the same hardware and footprint as the factory assembly, no upper receiver modification needed. It’s a simple, purpose-built upgrade for anyone rebuilding or refreshing an AR-15 upper.
