LWRC PMAG M3 Magazine LWRC Six8 6.8mm SPC Polymer Black
If you're running an LWRC SIX8 rifle, you need magazines built for that platform—and the LWRC PMAG M3 Magazine in 6.8mm SPC is purpose-built to do exactly that. Built on Magpul's proven M3 polymer technology, this magazine delivers the durability and reliability you'd expect from a modern defensive or hunting rifle, with an aggressive texture that grips your hand even when things get wet or dirty.
The engineering here is straightforward but smart: a stainless steel spring resists corrosion so your magazine functions reliably whether you're storing it loaded for years or running it hard in the field. The over-insertion stop on the spine prevents the magazine from seating too far into the magazine well, eliminating a common headache with compatibility. This is exactly the kind of thoughtful detail that separates a quality magazine from a mediocre one.
One critical note: this magazine is designed exclusively for the LWRC SIX8 platform. It will not work in standard AR15 lowers or other rifles. If you're building out your SIX8 with reliable, mission-ready mags, this is the obvious choice.

Frequently Asked Questions
Will this magazine work in my standard AR15?
No. The LWRC PMAG M3 is engineered specifically for the LWRC SIX8 platform and is not compatible with standard AR15 lower receivers or other rifle platforms.
What's the advantage of the stainless steel spring?
Stainless steel resists corrosion and rust, keeping your magazine reliable whether it's stored loaded for extended periods or used in wet, demanding conditions. It also meets USGI field compatibility standards, so you know it'll work when it matters.
What does the over-insertion stop do?
The over-insertion stop on the magazine spine prevents the magazine from seating too far into the rifle's magazine well. This ensures proper function and eliminates a common compatibility issue with some magazine and receiver combinations.
