AR-15 Extra Power Magazine Spring Replacement:
Upgrade the performance of your AR-15 with our Extra Power Magazine Spring Replacement. Made from heavy gauge premium spring steel, this replacement spring offers 15% more strength over factory mag springs, providing greater operating performance and reliability.
Leaving your 30 round magazine loaded for an extended period of time can cause the magazine spring to lose its intended stiffness, resulting in a weaker magazine spring that will not properly present the next round for your bolt to grab and feed into the chamber. To ensure reliability of your AR-15, it's recommended to replace your weaker factory mag spring with the Best Extra Power AR-15 Mag Spring, which will last longer and provide optimal performance.
This Extra Power Mag Spring is compatible with GI Mags, Magpul PMAG's, ProMags, and similar variations of these, excluding Hexmags.
Most shooters report that these MCARBO 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.
This is a great 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 preventative maintenance that should be conducted every three months to ensure the reliability of your AR-15.
Don't settle for a weaker standard mag spring that may cause Failure-To-Feed Malfunctions. Upgrade your AR-15 with the Best AR 15 Extra Power Mag Springs to give yourself the most reliability and performance out of your AR. Additionally, it's always a good idea to keep back-up replacement parts in case of panic buying in the future, or if you have a 10 round blocked magazine and move to a state where 30 round mags are allowed, you can use these to convert the restricted mags.
