AR-15 Extra Power 30 Round Magazine Spring Replacement:

  • Heavy Gauge Premium Spring Steel Extra Power AR-15 Magazine Spring Replacement

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 loose it's intended stiffness. It never a bad idea to keep back-up replacement parts in case if there is panic buying in the future as happened in the past. 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.

Most Shooters report that these M*CARBO Extra Power AR-15 Mag Springs feed much better than factory and provide more reliably. 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.

Bought these to replace the old tired and worn springs in my magazines. These springs are what all magazines should come with from the factory. No worries about storing loaded magazines with these springs.

Easy install. Blazing fast shipping.

Nice, I can feel the difference in tension immediately, Manually ran a full mag through my AR15, no problems. I used these springs to replace the ones in the HEXMAG . Then I took the old HEXMAG 30rd springs and used them in my RUGER Mini 14 20 RD mags. Didn't have to cut anything, Everything works great.
