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.

Built nice ? I did some Mexican injunity, elbow greese to make the trigger pins set, although I had little parts flying everywhere but found everything except a small internal take down pin lost in oblivion somewhere ,its ok that's what oops kits are for ? I like the trigger pull? my first lower I put together, there is a first time for everything ? thank you NFA
Ordered this set for my new .22LR..and I am impresed. I put the set into my FMK Polymer lower, and it has done as well as a standard Mil-Spec LPK...will be looking to purchase another very soon
Precise fit. Unimaginable that poly can be made into such critical parts. Molding and fit were perfect with the exception of very minor adjustment with a needle file. What's next , could new frontier armory come out with a tough poly carbine buffer tube so I can shave even more weight or maybe a poly delta ring?
Just what I wanted, everything was just excellent. Fit, finish and quality is far above average. Helped me build the ultimate lightweight rifle! Thanks New Frontier Armory.
Worked as advertised and described. All the parts fitted without a problem. I did have a problem with the selector detent but it was replaced quickly by NFA and solved the issue. I was able to lose a couple .oz off a lightwieght build. The LPK has held up to 800+rds of abuse. I will order from New Frontier Armory again.
