ProMag MOSA1 22 LR 25-Rd Blued Steel/Polymer Magazine Mossberg 715T

The ProMag MOSA1 is a 25-round detachable magazine built for the Mossberg 715T rimfire rifle chambered in .22 LR. It pairs a heat-treated blued steel upper body with a polymer lower body extension for reliable feeding, and uses an injection molded follower and a spring formed from music wire for consistent cycling.

Designed as a drop-in replacement magazine for the Mossberg 715T, the MOSA1 gives rimfire shooters extra capacity for plinking, training, and casual range sessions. Made in the USA by ProMag.
