Malaysian surplus went from 4 MOA to 2 MOA. Lol. 168 FGMM and IMI 175 are about 1.5 MOA. (10 round groups @ 100m from a bi-pod with a 6x.)

They put longer screws in part of the hand guard attachment, which helped stop the rotation I was having. However, the rail itself flexes way too much and hits the gas block. I put on an ALG V3 I had sitting around, which is much more rigid.

Time and about 1k more rounds will tell.

Did you test the accuracy after the rail change?
