Captain O, Welcome to the forum. After reading your post, I found a discussion on the CMPwebsite that mentions these mags. From what I read, they will function but are not of the highest quality.

I notice that the CDNN mags have gone up $4 each since January. Take a look at the "walnut finish - US wood" carbine stocks they are offering. Makes me wonder if they are "take offs" from some of the New Inland Carbines?
