Beltfedup Posted December 19, 2025 Report Share Posted December 19, 2025 Hello, I'm going to ask this question as simple as possible... I'm getting confused in all the conflicting information I've read about this particular situation.... I am wondering if this MPA defender will accept the standard ftf, cobray....ECT uppers? It is made out of all steel and was purchased around 2015... From what I think I understand is correct. Is that the newer ones that are made out of aluminum have a proprietary upper and won't accept all the older uppers and maybe a few other items?.... Thanks Quote Link to comment Share on other sites More sharing options...
