First Impressions of Lead & Steel Mil-Spec Lower Spring Kit w/ Grip Screw
The Lead & Steel Mil-Spec Lower Spring Kit w/ Grip Screw promises to be a reliable and durable solution for completing or repairing an AR-15 lower receiver. Lead & Steel claims this kit meets or exceeds mil-spec standards, offering peace of mind for both novice builders and experienced armorers. At a price point of $6.95, it presents an incredibly affordable option for ensuring the proper function of critical components within the lower receiver.
I’ve been building and maintaining AR-platform rifles for over a decade, often encountering issues with worn or broken springs. The lower receiver houses several small but essential springs that affect trigger pull, magazine release, bolt catch, and selector lever function. Replacing these springs with a quality kit can breathe new life into an older rifle or ensure optimal performance in a new build.
Upon receiving the kit, I immediately noted the clean packaging and the individually bagged components. The springs appeared well-made, free from any visible defects or corrosion. Compared to some generic spring kits I’ve used in the past, the Lead & Steel springs felt more robust and consistent. I was pleasantly surprised by the overall quality, especially considering the low price.
Real-World Testing: Putting Lead & Steel Mil-Spec Lower Spring Kit w/ Grip Screw to the Test
First Use Experience
I installed the Lead & Steel Mil-Spec Lower Spring Kit w/ Grip Screw in a lower receiver I was assembling for a new lightweight AR build. The installation process was straightforward; each spring fit perfectly into its designated location within the lower receiver.

The rifle performed flawlessly; there were no malfunctions or issues related to the lower receiver components. The trigger felt crisp and consistent, the magazine release was smooth, and the bolt catch functioned properly. I experienced no light primer strikes or failures to feed.

After several months of regular use, including multiple range trips and a carbine course, the Lead & Steel Mil-Spec Lower Spring Kit w/ Grip Screw has held up remarkably well. There are no signs of wear and tear, and all components continue to function as expected. The springs have maintained their tension, and there has been no degradation in performance.
Compared to previous experiences with less expensive spring kits, the Lead & Steel kit has proven to be significantly more durable and reliable.
