Description
If you own an LWRC SIX8 rifle, this is the magazine you need. Magpul and LWRC partnered specifically to design this PMAG for the SIX8 platform, and it shows in every detail. You get 30 rounds of 6.8mm Remington SPC capacity in a lightweight polymer package that's half the weight of traditional steel magazines.
M3 Polymer Construction Built to Last
The M3 polymer body uses the same material science that goes into professional-grade magazines. It's impact and crush resistant, designed to exceed rigorous military performance specifications. The constant-curve geometry inside feeds rounds reliably shot after shot, and the anti-tilt follower keeps rounds stacked properly under pressure.
Practical Features That Matter
The aggressive texture on the front and rear gives you solid grip control during speed reloads, and the slim floorplate doesn't add bulk to your kit. An over-insertion stop on the spine prevents your magazine from seating too far into the magwell, protecting both the magazine and your rifle. The USGI-spec stainless steel spring handles environmental exposure without corrosion issues, and the paint pen dot matrix on the base makes it easy to mark and organize your mags.
LWRC SIX8 Exclusive Design
This magazine is engineered specifically for the LWRC SIX8 lower receiver and won't function in other 6.8mm platforms or standard AR-15 rifles. That tight engineering spec means you get the best possible fit and feed reliability in your Six8 build.

Frequently Asked Questions
Will this LWRC PMAG work in my standard AR-15 or other 6.8mm rifles?
No. This magazine is designed exclusively for LWRC SIX8 platform rifles and won't function in standard AR-15 lower receivers, older 6.8mm rifles, or any other manufacturer's platform. The SIX8 uses a proprietary magwell geometry that requires these specific magazines for reliable operation.
How does the polymer construction compare to steel magazines?
The Magpul M3 polymer is lighter than steel without sacrificing durability. It's impact and crush resistant, built to exceed military specifications, and the stainless steel spring handles corrosion just like steel magazines would. You get reliability and less weight in your kit.
What does the over-insertion stop do?
The over-insertion stop on the spine prevents the magazine from seating too far into your rifle's magwell. This protects both the magazine and your gun from damage while ensuring the mag sits in the proper position for reliable feeding.
Can I use this magazine in competition or training?
Yes. The 30-round capacity and reliable Magpul design make this a solid choice for training, practice, or any shooting where high volume is useful. Just verify that whatever you're participating in allows 30-round magazines, as capacity restrictions vary by location.
