New Frontier Armory LW Blow Back Hammer for .22LR / 9mm Uppers

The New Frontier Armory polymer blow back hammer replaces the standard polymer hammer that comesinstalled onthe LW-4 complete polymer lower. The blowback hammer has been designed slightly narrower, resulting in better compatibility with dedicated AR-15 .22LR, 9mm and otheruppers 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.

    Lw blowback hammer

    Posted by Ribit on 6th Mar 2023

    Have not been able to use it yet, but looks like it will work just fine in my next build. Its a lightweight polymer trigger for 22LR, and 9mm. Item arrived quickly, and exactly as described. As soon as I get to use it I will leave another review, but I definitely recommend it to anyone building a 9mm, or 22lr looking to build a lightweight rifle it's a must have. I love all my NEw Frontier Armory products, and I have quit a few of there products. NFA is my go to for AR style builds.
