someone asked if the ak74 kits have dual rivet, feed ramp, type barrel trunnions.  Can you please explain to me what this is?  What are the other types.  Which is better.  I have three Bulgarian ak74 kits and would like to know what I have.

BTW, the reason that I posted this question here is that I don't want to hijack the sales post of a vendor.

lol, i was way off!

The bullet feed ramp on AKS-74 had two rivets while on the Ak-74 they only had on rivet.

Not sure if this holds true for all 74's, but when the batches of true sidefolders came in that is how they were. IIRC.

Thanks for the education.  I'll take a look at the Bulgy side folder that I just received from ORF and compare it to the fixed stock Bulgies that I have.
