An AR-15 spring kit from Luth-AR gives you the replacement springs you're likely to need over the life of your rifle. Springs wear, get lost during field strips, or break from heavy use—and when they do, having the right parts on hand beats waiting for a gunsmith or mail delivery. This kit assembles the essential springs that keep your AR-15 functioning, so you can get back to shooting instead of troubleshooting.
Whether you're a competition shooter, a hunter who relies on your rifle, or someone who just runs a lot of rounds through your gun, springs are wear items. The Luth-AR spring kit includes the springs most commonly replaced or lost: ejection port, hammer, trigger, forward assist, magazine catch, selector, disconnector, bolt catch, extractor, detent, buffer retainer, and charging handle springs. Having them in your toolbox or range bag means you're prepared for most common spring-related issues without having to order individual parts.
This kit is straightforward to use if you're comfortable field-stripping your AR-15. Each spring is included so you have options and backups. Keep one in your go-bag, range pack, or home maintenance kit—it's the kind of thing you don't think about until you need it.

Frequently Asked Questions
Will this AR-15 spring kit fit my rifle?
This kit is designed for standard AR-15 pattern rifles. If you have a custom or non-standard build, verify that your rifle uses common AR-15 components before ordering.
Do I need tools to install these springs?
Installation depends on which spring you're replacing. Most AR-15 spring replacements require only basic gunsmithing knowledge and tools like a punch set and small screwdrivers. If you're not comfortable field-stripping and reassembling your rifle, have a qualified gunsmith handle the work.
What if I only need one or two springs?
This kit gives you a complete assortment, including extras like two detent springs. It's designed to cover most common spring failures and replacements, so you'll have spares for future repairs or as backups.
