ProMag Magazine Springfield M14, M1A 308 Winchester 50-Round Drum Polymer Black

If you own a Springfield M14 or M1A and want to break the monotony of standard 20-round mags at the range, the ProMag 50-Round Drum Magazine for Springfield M14/M1A offers something most .308 Winchester shooters don't get to experience: high-capacity fun without swapping platforms. While AR owners have enjoyed drum mags for years, this polymer drum brings that extended firepower to the M14 platform—perfect for those range days when you want fewer reloads and more trigger time.

Built with serious durability in mind, this drum combines a proprietary Zytel-based polymer housing (originally developed by DuPont) with a carbon-steel lip reinforcement that's overmolded into the upper feed tower. That steel lip does double duty: it strengthens the feed area and improves the mag's lubricity, so it seats and functions smoothly in your rifle. Inside, a heat-treated stainless-steel spring pairs with an injection-molded follower to keep rounds feeding reliably through all 50 of them.

The magazine is chambered exclusively for .308 Winchester and 7.62 NATO—if that's your M14/M1A's diet, you're covered. It ships in all-black polymer finish and is made in the USA, so you're supporting domestic manufacturing while you're stocking up on range capacity.

Fair warning: drum mags are fun but they're also heavier and bulkier than standard box mags, and some shooters find them slower to reload. They shine at the bench or on the range where you want extended fire; they're less practical for hunting or duty use. Load it up, get behind your M14, and enjoy what it's like to send serious volume downrange.

Frequently Asked Questions

Will this drum magazine work with my Springfield M14 or M1A?

Yes, this ProMag drum is designed specifically for the Springfield M14 and M1A platforms in .308 Winchester / 7.62 NATO. It will not work with other rifle platforms.

What ammunition does this magazine accept?

This drum magazine is chambered exclusively for .308 Winchester and 7.62 NATO cartridges. Do not attempt to use it with other calibers.

What makes the carbon-steel lip reinforcement important?

The overmolded carbon-steel lip on the upper feed tower strengthens the feed area where rounds are stripped from the drum and into the chamber. It also improves lubricity, helping the magazine feed smoothly and reliably through all 50 rounds.

Is this magazine suitable for hunting or tactical use?

While the magazine is robust and reliable, drum mags are heavier and bulkier than standard box magazines, and some shooters find them slower to reload. They're best suited for range shooting and extended fire scenarios; standard 20-round mags remain the practical choice for hunting and field use.
