| Has anyone tried using a 5.45 upper on their RR/RLL/dias with any success? |
| I've tried two different 5.45x39 uppers, a S&W and one I built with an Alexander Arms barrel and a bolt from Olympic, on my RR M16. Both run great with C-product mags. I use the extra heavy hammer spring that came with the S&W upper and cheap Bulgarian surplus ammo. |

I use the extra heavy hammer spring that came with the S&W upper and cheap Bulgarian surplus ammo. My S&W runs great too! I just shortened it to 10.5 and it runs like a top with my RDIAS, but you have to use the heavy hammer spring. |

I've been running them for a couple years now. I initially used a modified AR-47 lower....actually just modified the mag catch. Then later used the MGI AK74 magwell when it came out.
This is a custom setup using the AR47 lower. 11.5" Bulgarian chrome lined barrel headspaced to M16 barrel extension:
