NUPROL 370rnd W-Mag B High-Cap Magazine for M4/AR15 AEG

Featuring dot pattern on the side and rubberised buttplate, this is for those of you looking for a more modern M4 hi-cap magazine.

This magazine holds 370 BBs and is loaded through its fill window, located on the top of the magazine body and wound using the wheel at the bottom.

This magazine is constructed from strong polymer with a rubberised baseplate complete with an extension to allow for “mag padding” and a dot matrix so you can mark your magazines for I.D and admin purposes.

This magazine takes its name from the mock witness windows located on either side of the magazine, through which you can see the internal gear and BBs, letting you know how much blasting you have left.
