Hello All,

Not a Nube, just need some additional brainpower and practical experience.

I have a number of Romanian kits that I am about to build. I have taken stock of all of my spares and stuff. After thinking about it all, I think I want to build two AK rifles in 5.45x39. Cool! Except; my Romy kits are 7.62x39. So, here are my questions:

1. Can I buy a Bulgarian 5.45x39 Barrel from Copes, and expect it to fit into the Romy front trunion?

Not sure, I have never taken the time to measure the parts.

2. Will my 7.62x39 Bolt work unmodified for the 5.45x39 cartridge?

3. Will I need to aquire anything else to replace specific parts in my kits to make this conversion work?

Make sure the barrel parts will press on and be tight enough, I was working on a Bulgy 74 today and IIRC it had a 90deg gas block, the Romy G is 45 deg. If that would work then your GTG.

4. My intent is to use the AKreceivers.com receivers for the builds. Any known issues there?

I have built 20+ guns with these receivers, the 7.62 receivers seem to let the blot carrier hang when charging the gun. That hasn't been a problem with the 5.45 receivers.
If your in Cali you won't be able to order their receivers direct. They only ship to 1 FFL in the State and you'll need to buy from them, http://www.prkarms.org/ or at least thats what I was told by the owner when he called me.

I am reaching out to the Old Dogs here, but any comments ar welcome.

Thanks All,

no rim is too large

sell or trade one of your g kits to fund a 74 kit
