Tested and developed with Rifle World Champion Jarkko Laukia, our +6rd PMAG extensions will fit all Gen M3 PMAGs and extend their capacity by 6 rounds.
Made out of our tried and tested durable and lightweight polymer. Has a secure, strong single screw lock. Compatible with Ranger bases and similar accessories.
The extensions can be stacked to fine tune your mag length for a stage if needed. Generally, the stock spring in a magazine is good for 1x extension, so if you have a 20 round mag and you extend it to 32, you need a spring from a 30 round mag. This would in theory enable you to add a third extension with this same spring.
