AR-15 Extra Power 30 Round Magazine Spring Replacement:
- Heavy Gauge Premium Spring Steel Extra Power AR-15 Magazine Spring Replacement
- Works for GI Mags, Magpul PMAG's, ProMags and similar variations of these (Except Hexmags)
15% Stronger AR-15 Magazine Spring over Factory Mag Spring
When leaving your 30 round magazine loaded for any extended period of time your magazine spring will eventually take a set, thereby reducing the amount of load it can handle. This results in a weaker magazine spring that will not properly present the next round for your bolt to grab and feed into the chamber.
Remember to change out your fully loaded magazines every 90 days by unloading and reloading a different fresh magazine.
Replace your weaker factory AR-15 mag spring with the Best Extra Power AR-15 Mag Spring that will last longer and provide greater operating performance. If you are rebuilding your GI Mags or just upgrading your brand new PMAG's it's worth doing now before your next Failure-To-Feed Malfunction. You should also use this opportunity to clean the inside of the magazine, inspect the follower and floor plate and inspect the feed lips for any damage or cracking. It's a great preventative maintenance that should be conducted every 3 months to ensure reliability of your AR-15.
The M*CARBO Extra Power Mag Springs improve reliability a lot, rebuild or not!
If you plan to store your mags fully loaded like the rest of us then over time you should be concerned that your factory mag spring will eventually lose it's intended stiffness. It's never a bad idea to keep back-up replacement parts in case of panic buying in the future. If you have a 10 round blocked magazine and you move to a state where 30 round mags are allowed, you can use these to convert the restricted mags.
AR-15 Extra Power 30 Round Mag Springs will work for GI Mags, Magpul PMAG's, ProMags and similar variations of these. **Will not work for Hexmags**
Most Shooters report that these M*CARBO Extra Power AR-15 Mag Springs feed much better than factory and provide more reliability. The stiffer magazine spring puts more tension between the floorplate and follower, while holding 30 rounds per mag. Go ahead and switch out the weaker standard mag springs with the Best AR 15 Extra Power Mag Springs to give yourself the most reliability and performance out of your AR.
Q: How does this spring affect the feed lips on polymer mags? Would the extra tension cause them to "flex" sooner?
A: The extra tension won't compromise the structural integrity of the feed lips. We designed this spring to provide extra power but not so much that it creates extra problems. Thanks for asking that one.
