There was a time when a 40-round magazine seemed to be almost de rigueur for an automatic rifle, then they seemed to fall out of fashion.
Now it looks as though where the iconic RPK led, MagPul follows. Today they announced their 40-round M3 PMAG, specifically designed to be fully compatible with many types of AR and NATO STANAG platforms….
The 40-round PMAG is only 2 1/8″ longer than its 30-round brother but gives you 10 more rounds. The M3 PMAGs feature a re-designed bolt catch notch and a protruding lip on the magazine spine to prevent over-insertion into the mag well – which would cause a stoppage.
The M3 PMAGs also incorporate new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed military specifications.
Finally, modified internal and external geometry permits operation with a wide range of non Colt-spec platforms such as the HK® 416 and MR556A1, M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.
Manufacturers Suggested Retail Price is $19.95. The 40-Round M3 PMAG is prohibited in several states and is also an ITAR restricted item.
