Description
If you run a Colt M4 in .22 LR and want a spare mag that doesn't break the bank, the ProMag COLA30 checks the boxes. This is a straightforward detachable magazine designed specifically for your rifle, holding 30 rounds and delivering solid reliability in the field.
ProMag COLA30 Construction and Materials
The body is molded from DuPont Zytel polymer, a material ProMag has used for years to balance durability with light weight. The injection-molded mag follower and heat-treated chrome silicone wire spring work together to feed rounds consistently without hanging up. That spring is tough enough to handle regular loading and unloading cycles. Everything is finished in matte black and made right here in the USA.
Perfect for Extended Shooting and Training
With 30 rounds on tap, you're spending more time downrange and less time reloading. Whether you're working on accuracy at the range or just enjoying some casual plinking, having multiple mags with decent capacity lets you focus on what matters. Keeping a few of these around means you're never stuck waiting for reloads between strings.
Important Compatibility Note
This magazine is built for Colt M4 rifles specifically. It will not work with Ciener or G.I. style .22 conversion platforms, so make sure you're running a Colt before ordering. If you've got the right rifle, it'll drop right in and lock firmly in place. ProMag backs this mag with a lifetime warranty against manufacturing defects, so you're covered if something goes wrong.
