The ProMag COL19 is built for shooters who want a no-nonsense, short-profile magazine without the bulk of standard 20 or 30-round options. This 5-round magazine features a heat-treated steel body with black oxide finish, engineered to handle both .223 Remington and 5.56 NATO rounds across any AR-15 platform.
The magazine body is constructed from high-carbon heat-treated steel and features TIG welding throughout for structural integrity. The internal spring is precision-wound from heat-treated chrome-silicon wire, a material proven for long-term durability and consistent performance. The follower and baseplate are molded from tough polymer material selected for durability and reliable cartridge alignment shot after shot.
This is where the COL19 really shines. The magazine sits flush with or very close to the bottom of the mag well, eliminating the magazine from interfering with bipod legs or bench rests. That short profile means you can get into a solid prone or bench position without worrying about the magazine hanging up when you're trying to get low for better sight alignment. You can also reload while the rifle is mounted on a bipod without awkward repositioning.
ProMag magazines come backed by a lifetime warranty against manufacturer defects. The COL19 is straightforward—no gimmicks, no over-engineered follower systems, just a solid steel magazine designed to work with your rifle. Each magazine is machined for exceptional quality and guaranteed to feed and function reliably. Made in the USA.
Yes, that's one of the main advantages. The flush-fit design keeps the magazine profile low and tight to the magazine well, so it won't interfere with bipod legs or bench shooting setups. You can get lower on the gun and reload while it's mounted on a bipod without repositioning.
This steel magazine is machined for consistent quality and designed to feed and function reliably. It uses a heat-treated chrome-silicon spring and precision-molded polymer follower. Like any magazine, it's worth testing a few rounds through your specific rifle before relying on it for critical applications.
ProMag backs all their magazines with a lifetime guarantee against manufacturer defects. If you experience any defect in workmanship or materials, you can return it to ProMag for replacement.
Yes, the magazine is chambered for both .223 Remington and 5.56 NATO ammunition. It's fully compatible with any standard AR-15 platform rifle in either of those calibers.
