Description
Finishing a stripped AR-15 lower usually means chasing down a dozen tiny springs, detents, and pins that all have to be right. The White Label Armory WLA-LOW-1013-01 takes that headache off your plate by packing everything into one complete kit. It covers the full fire control group, the controls, all the small parts, and an A2 grip so you can go from bare receiver to a working lower without a second shopping trip.
What Goes Into the WLA-LOW-1013-01 Build
This is the fully loaded version of White Label's lower kits. You get the hammer and trigger with their springs and pivot pins, the disconnector and its spring, the safety selector with detent and spring, the bolt catch and its plunger, spring, and roll pin, plus the magazine catch, button, and spring. Round that out with both takedown pins, the pivot pin and detents, the buffer retainer and spring, and a trigger guard with hardware. The A2 pistol grip and grip screw come along too, so the furniture side of the lower is handled.
Why Builders Trust This White Label Lower Kit
White Label Armory makes a real point of keeping these kits domestic. Every part is 100 percent American-made and machined to mil-spec standards, with no foreign, polymer, or MIM parts in the mix. The parts carry a phosphate finish, which is the classic mil-spec coating that resists corrosion and holds oil well inside the receiver. Because it is cut to mil-spec dimensions, the kit is meant to drop into any standard mil-spec AR-15 lower.
Getting the WLA-LOW-1013-01 Installed
If you have built a lower before, this kit will feel familiar and go together smoothly. First-timers can absolutely tackle it too, though a roll pin punch set, a bench block, and a little patience with the bolt catch and trigger guard roll pins go a long way. Keep the small detents and springs corralled while you work and you will have a functioning lower in an afternoon.

Frequently Asked Questions
What does the WLA-LOW-1013-01 lower parts kit include?
This is the complete version, so it carries everything needed to finish a stripped AR-15 lower. That means the full fire control group with hammer, trigger, disconnector, and springs, plus the safety selector, bolt catch, magazine catch, takedown and pivot pins, buffer retainer, trigger guard, and an A2 pistol grip. In short, you are not left hunting for extra small parts to wrap up the lower.
Will this kit fit any AR-15 lower receiver?
The kit is machined to mil-spec dimensions and is designed to drop into any standard mil-spec AR-15 lower. If your receiver follows the mil-spec pattern, these parts should fit and function as intended. Non-standard or proprietary lowers can vary, so it is worth confirming your receiver is mil-spec before ordering.
What is the phosphate finish and why does it matter?
Phosphate is the traditional mil-spec coating used on internal AR-15 parts. It resists corrosion and holds oil well, which helps the small springs and pins stay protected inside the receiver over time. It is a proven, no-nonsense finish that matches what you would expect on a duty-grade build.
Is the WLA-LOW-1013-01 good for a first AR-15 build?
It works well for both first-time builders and folks who have done this before. Having every part in one box removes the guesswork of sourcing individual pieces. A basic roll pin punch set, a bench block, and some patience with the bolt catch and trigger guard pins will make the install go smoothly.
