Description
The ProMag COLA30 is a 30-round detachable 22 LR replacement magazine purpose-built for the Colt M4 .22 LR semi-automatic rimfire rifle. Engineered around a proprietary DuPont Zytel polymer body, the magazine delivers light carry weight, excellent corrosion resistance, and the durability needed for high-volume range sessions and rimfire training.
A heat-treated chrome-silicon spring and an injection-molded polymer follower feed rounds smoothly, while the matte black finish matches factory Colt furniture for a low-profile look. The magazine seats and drops free in standard Colt M4 .22 LR magwells and serves equally well as a primary or spare.
Made in the USA by ProMag, a long-established American manufacturer of firearms accessories and magazines, the COLA30 is a reliable companion for your rimfire M4. Note: This magazine is designed for the Colt M4 .22 LR rifle and is not compatible with Ciener or G.I. style .22 conversion upper receivers.
