*NOTE: Some .22LR, 9mm and other blow back style upper receivers use a groove in their BCG that is too narrow for the polymer hammer that comes standard on the New Frontier Armory LW-4 complete carbon fiber lower receiver. In these cases you will need to switch to a blow back style hammer available by clicking HERE. The blow back style hammer, once installed, will run all rim fire and pistol uppers, and still work fine with standard mil-spec rifle uppers.
**USE OF ANY MAGWELL ADAPTERS WILL VOID THE FACTORY WARRANTY!!
OPTIONS: Also available in a stripped version.
AVAILABLE ACCESSORIES: Blow Back Hammer for use with .22 caliber uppers
Q: Can I build my upper while attached to the lower receiver?
A: NO! When assembling your upper receiver DO NOT torque the barrel nut or muzzle brake while the upper is attached to the LW-4 (or any other model) lower receiver. Assembling the upper improperly could cause damage to the lower receiver and will NOT be covered under the factory warranty. When assembling an upper you should use a reaction rod or a vise block specific for assembling upper receivers.
Q: Why is the safety selector able to turn to safe regardless of hammer position
A: This is an added safety feature that allows the firearm to be put on “Safe” whether the hammer is cocked or forward. We believe this is a much safer solution to ensure the safety of our users and will not affect normal use in any other way.
The New Frontier Armory LW-4 Complete Carbon Fiber AR-15 lower receiver is proudly MADE IN THE USA by hard working American men and women and is covered under a lifetime warranty against manufacturer defects when used as directed.
