Leber V2 MP5 Lower Review | AR‑15 FCG Compatible Housing

🛠️ Introducing the Leber V2 – AR‑15 Fire Control Lower for MP5/MP5K

Launched March 6, 2025 by designer s3igu2, the Leber V2 is a ground‑up redesign of earlier ARMP5/Leber V1 models. It's purpose‑built to accept AR‑15 fire control group (FCG) components and deliver high performance in a reinforced housing system X (formerly Twitter)+13Odysee+13Odysee+13.

🔍 Why Leber V2 Stands Out

🌟 Key Features

• Complete compatibility with standard AR‑15 FCG, including triggers, hammers, and disconnector OdyseeOdysee.

• Steel-reinforced SCS mounting plates and trigger housing, dramatically improving durability over V1 and preventing cracking Falador Design.

• Super‑safety compatible, enabling forced reset operation and safer operation with suppressors Falador Design+1X (formerly Twitter)+1.

🧩 Design & Build Improvements

• A refined grip angle and internal ergonomics optimized for improved handling Odysee+5Falador Design+5Odysee+5.

• Modular slip-trip design (beta v3 iterations) for customizable fire rate and smoother cycling Odysee+6Reddit+6Falador Design+6.

🧰 How to Install Leber V2

1. Download the Leber V2 assembly guide (available March 5, 2025) on Odysee to walk through fitting and parts layout X (formerly Twitter)+12Odysee+12Odysee+12.

2. 3D print or purchase housing in PAHT or PPA (or order steel-reinforced kit via Falador Design), then install your AR‑15 FCG into the steel SCS plates Falador Design.

3. Add a slip trip (v3 recommended), buffer spacer, and springs as per instructions to dial in firing characteristics Odysee+8Falador Design+8Reddit+8.

💬 Community Feedback & Beta Insights

On r/MP5, early beta testers highlight:

“Leber v2 is a completely reworked system … holds the tension … far longer than V1”“It should slow down your rate of fire … keep you from getting roller dents with suppressor & brace builds.” Reddit

Enthusiasts mention that transitioning from V1 to V2 allows reuse of many earlier components, simplifying upgrades.

🧠 Who It’s For

The Leber V2 is perfect for:

• Builders aiming to convert MP5 or MP5K platforms to run standard AR‑15 FCG.

• Anyone looking to upgrade durability and reliability beyond current 3D printed lowers.

• Enthusiasts wanting super‑safety functionality and full forced‑reset capability.
