This kit is engineered to give you a tighter, more positive safety engagement than many stock options. The heat-treated 4140 components stand up to repeated use while the black oxide finish reduces wear and glare. It’s a great upgrade for custom AR-style builds or anyone replacing worn safety parts.
Designed for AR-15 platform installations; may be adapted for other platforms (see note below). Confirm fit with your lower/FCG before installation.
For use in certain non-AR platforms (for example MP5 variants) additional lower modifications or specific lowers that accept AR FCG parts may be required — consult manufacturer notes and fitment guides.
Recommended: Install by a qualified gunsmith. Improper installation can cause unsafe function. AS Designs and FTA Tactical recommend professional installation for best results.
