This magazine base pad is designed around the stock base pad for the 17-round magazine and to be paired with our MK1 backstrap.
Overall strength and longevity of the base pad will be dependent on the type of filament used and any damage caused by tactical reloads.
If tactical reloads are common, we recommend using the MK2 solution, which is designed specifically for the 3D print platform, providing additional strength at the weakest points.
