AR-15 PMAG Gen 3 – Magazine Extension – +5 Capacity – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Shield Arms PMAG Gen 3 +5 Magazine Extension adds five rounds to compatible Magpul PMAG Gen M3 magazines using a machined aluminum extension body with anodized finish options. This is built for shooters who want more capacity and a more durable extension setup for training, range use, or competition work.
Fitment
- Fits Magpul PMAG Gen M3 / Gen 3 magazines
- Adds +5 rounds
- Designed for the PMAG Gen 3 magazine body family
Does NOT fit
- Not for PMAG Gen 2 magazine bodies
- Not a universal AR magazine extension
What it does
This extension increases capacity while replacing the standard floor plate with a stronger aluminum body. Shield Arms also calls out an easy-access floor plate design that helps service the spring and follower without removing the extension from the magazine body.
Why it’s worth it
This one is useful, not gimmicky. More rounds, solid construction, and actual serviceability beat cheap extensions that feel like a dare.
