I posted this on AK-47.net and got one response that offered to send me an extra one they had laying around. Still looking for a second one:
--------------------------------------------
I need help with two muzzlebreak questions:
1) I have a pre-ban Hungarian AK-47 underfolder (7.62X39) with a slant-style muzzlebreak. Does anyone know where I can find an AK-74 style screw-on muzzlebreak that will fit the rifle?
2) I have a post-ban Polytech AK-47 (7.62X39) that I put a pistol grip on using a K-var furniture set (this did require a lot of Dremelling to fit!) and an RSA trigger group for a total of 6 U.S. parts. There is a nut welded over the threads. I am looking for an AK-74 style screw-on muzzlebreak that fill fit this rifle. My plan is to take it to a welder, Dremmel off the nut, screw on the muzzlebreak and weld it with silver solder.
The problem is finding the AK-74 style break with the proper thread for both of these rifles.
Thanks ahead for any info.
