I was looking back in this thread... post #126... and noticed over a year ago (and 1,500 rounds) I installed a bullet guide on my 5.45 Saiga conversion, but it looks like the .223 flat guide in the Dinzag reference in post #126 (and below).
Sorry to hijack this 7.62 thread... has anyone else put a bullet guide in a 5.45 that has the sloped front edge?
Again I have fired ~1,500 rounds
without any issues with this guide and 9 different surplus mags (I think bulgarian).
