Luth-AR 9mm Carbine Buffer Assembly Mil-Spec

Luth-AR 9mm Carbine Buffer Assembly

This is a complete, ready-to-install buffer assembly designed specifically for 9mm AR-15 carbines. It provides everything you need for proper bolt carrier group function in a 9mm platform.

What's Included

• 9mm Carbine Buffer — Properly weighted for 9mm recoil impulse
• Mil-Spec Carbine Buffer Tube — 6-position adjustable stock compatible
• Carbine Recoil Spring — Matched to buffer weight
• Castle Nut — Secures tube to receiver
• End Plate (Latch Plate) — Receiver mounting hardware

Why This Matters

Buffer weight is critical in 9mm AR builds. Too heavy, and your bolt carrier won't cycle properly. Too light, and you'll experience reliability issues. This assembly is engineered specifically for 9mm ballistics, ensuring reliable feeding, firing, and extraction.

The Mil-Spec diameter tube works with standard AR-15 receivers and accepts any Mil-Spec stock, giving you flexibility in your build or upgrade.

Installation

This is a straightforward drop-in component for gunsmiths and experienced builders. If you're new to AR assembly, consider having a qualified gunsmith install it to ensure proper function and safety.
