- Manufacturer: New Frontier Armory
- Model: LW Blow Back Hammer for .22LR / 9mm Uppers
- Caliber: Multi blowback operated calibers (.22LR, 9mm, etc, etc)
- Compatible With: LW-4 Complete Polymer Lower
The New Frontier Armory polymer blow back hammer replaces the standard polymer hammer that comes installed on the LW-4 complete polymer lower. The blowback hammer has been designed slightly narrower, resulting in better compatibility with dedicated AR-15 .22LR, 9mm and other uppers that do not use a bolt carrier with a mil-spec slot.
This part is not required for standard centerfire uppers but will work with them as well once it is installed.
If you are ordering an LW-4 at the same time and would like to have us install this part for free – please add your request to the comments section of your order.
Although the installation of this hammer is a simple task, we advise you use a trained gunsmith to perform the work and we will not be held responsible for any damage caused to the lower or parts during install.
The New Frontier Armory LW Blow Back Hammer for .22LR / 9mm Uppers is proudly MADE IN THE USA by hard-working American men and women.
