Frequently Asked Questions
Will this BCG work with my existing AR-15 lower and standard mil-spec components?
Yes. The Angstadt Arms 9mm BCG is designed to work with a standard AR-15 hammer, meaning you do not need to swap out your fire control group or other lower parts. It is a direct drop-in solution for dedicated 9mm AR-15 lower receivers configured for either GLOCK or Colt style magazines.
What is QPQ Black Nitride and why does it matter for a bolt carrier group?
QPQ (Quench-Polish-Quench) Black Nitride is a salt bath ferritic nitrocarburizing finish applied to the steel surface. It penetrates the metal rather than simply coating it, resulting in exceptional hardness, corrosion resistance, and lubricity. For a BCG, this means smoother cycling, reduced fouling buildup, easier cleaning, and longer service life compared to traditional phosphate finishes.
Can I use this BCG with a Law Tactical folding stock adapter?
Yes — this is one of the standout features of the Angstadt Arms 9mm BCG. It includes a removable weight that, when removed, provides the clearance needed for the BCG to cycle properly when used with a Law Tactical folding stock adapter, making it an excellent choice for compact or folding PCC builds.
