Frequently Asked Questions

Will this magazine fit both the Springfield Armory M1A and military M14 rifles?

Yes. This ProMag magazine is designed to be compatible with Springfield Armory M1A rifles as well as standard M14-pattern platforms that accept the same double-stack detachable box magazine. Always verify fitment with your specific variant before purchasing, as some aftermarket builds may have tighter tolerances.

What does "10-round capacity in a 20-round body" mean, and is it California-legal?

This magazine uses a full-size 20-round steel body but is internally blocked at the factory to hold a maximum of 10 rounds, making it compliant with California's magazine capacity restrictions. The block is a permanent modification intended to meet state regulations. It is sold as a California-compliant magazine, but buyers should confirm current local laws apply to their situation, as regulations can change.

How does the chrome silicon wire spring improve feeding reliability compared to standard springs?

Chrome silicon wire is a premium spring steel alloy prized for its high tensile strength and resistance to fatigue over thousands of compression cycles. ProMag precision-winds and heat-treats each spring to maintain consistent follower pressure from the first round to the last, reducing the likelihood of misfeeds, failure-to-feed malfunctions, and premature spring set common in lower-quality magazines.
