Featuring a high-strength injection-molded polymer follower and a high-tensile steel spring, the Atlas Gunworks Lockback Follower Kit is a drop-in magazine upgrade kit, favored by new and experienced shooters across the country. The self-lubricating polymer follower delivers proper cartridge alignment for smooth feeding performance, while the +18% spring drastically improves feeding performance, reducing the risk of magazine-related jams and failures. Plus, Atlas’s proprietary Lockback technology delivers a positive lockup when empty for safe and consistent operation. Better yet, this kit offers quick tool-free installation for quick, field-ready service right out of the box.
