I posted this on another forum, but feel that it may help here so here it goes:
"I have this SLR 101 S Bulgarian milled receiver that cost me under $800.00 NIB out the door a few yrs back with OD green furniture.
K-Var Corp. ™
The new US milled receivers should be better than the Bulgarians and the Bulgarians are tack drivers, but the new MSRP are double the price I paid out the door a few yrs back.
If you got the dough, then nothing will beat a milled receiver AK so get a used Bulgarian or a new high dollar US made receiver.
I got a stamped Maadi that aside the trigger slap (easy fixed if the owner wants to) shoots fine for an AK, but side by side the milled receiver is a higher quality rifle by a long shot and also shoots where you aim (unlike most stamped AKs).
If I got the dough, I would go with the SAM7-13, sweet rifle."
