I have a Polytech M14S and my question is can I fit it into the EBR with out any issues? I am thinking of Picking up the Sage EBR. Thank you for your help and opinions. On a note as well does any one make Polymer mags for the m14/m1a? My Polytech HATES steel mags, won't ever function right but runs flawlessly with my one and only unmarked polymer magazine. All the steel have FTF or the springs are to weak and rounds poped out while an empty case was being ejected. However Sold them to a fella and he hasn't had any of the problems that I just mentioned.
