Lone Eagle 839 Posted August 8, 2014 Report Share Posted August 8, 2014 The only parts that won't interchange are the recoil spring, barrel, and bolt(and related bolt parts). Member on another forum rebarreled his 74 to 47 caliber, and this was all he changed. Quote Link to post Share on other sites

But the question is: every other parts i have to take from AK-74 or AK-47? Or is it all the same and i can take it from AK-74 OR AK-47? W8lifter mean i have to take it from AK-74. Right?

These rifles are based on the AK-74. All parts that did not need to be modified to accommodate the 7.62 can be replaced with AK-74 parts. The recoil spring, bolt carrier, firing pin, dust cover, gas tube, etc etc should be taken from the AK-74. Basically the only replacement parts you CANNOT just drop in from the AK-74 are the extractor, bolt, barrel and magazines of course. Quote Link to post Share on other sites

Mullet Man 2,114 Posted August 15, 2014 Report Share Posted August 15, 2014 Bolt carrier is specific to saiga/100 series guns too, since they use a thin stem bolt. Quote Link to post Share on other sites
BigChongus 765 Posted August 17, 2014 Report Share Posted August 17, 2014 Bolt carrier is specific to saiga/100 series guns too, since they use a thin stem bolt. AK-74 carriers are compatible with these as they also used the thin stem bolts. Quote Link to post Share on other sites
Mullet Man 2,114 Posted August 17, 2014 Report Share Posted August 17, 2014 (edited) What do Bulgarian Arsenal AK's use, '74 type parts? My Saiga stuff wont interchange with my Arsenal SLR107cr. I thought Saiga's used 100 series/'74M parts which were compatible, but aren't compatible with '74 non 'M' parts. Edited August 17, 2014 by Mullet Man Quote Link to post Share on other sites
BigChongus 765 Posted August 17, 2014 Report Share Posted August 17, 2014 Apparently the SLR (or maybe just the 107cr?) is the exception, which is why they won't swap with other Saiga/74 parts. Otherwise, for garden variety Saigas/SGLs, 74 carriers are g2g: https://www.k-var.com/shop/AK-046R.html Quote Link to post Share on other sites
BigChongus 765 Posted August 17, 2014 Report Share Posted August 17, 2014 (edited) Just out of curiosity, what won't swap on your 107? I'm reading from a few places that the 107's guts are AKM based, which would explain it. Assuming that's true, anyway. http://glocktalk.com/forums/showthread.php?t=1424978 Edited August 17, 2014 by W8lifter Quote Link to post Share on other sites
Mullet Man 2,114 Posted August 17, 2014 Report Share Posted August 17, 2014 Interesting reads. SLR107cr has a fat bolt, which is not interchangeable with the Saigas thin stem carrier and vice versa, obviously. Perhaps my nomenclature is fail when I say '74M. Quote Link to post Share on other sites
BigChongus 765 Posted August 17, 2014 Report Share Posted August 17, 2014 Actually, that seems like a huge plus for the 107. An AKM based 7.62 seems a lot more convenient as far as replacement parts IMO. Quote Link to post Share on other sites
AKdomination 1 Posted August 20, 2014 Report Share Posted August 20, 2014 Interesting reads. SLR107cr has a fat bolt, which is not interchangeable with the Saigas thin stem carrier and vice versa, obviously. Perhaps my nomenclature is fail when I say '74M. The saiga has the correct 100 series bolt based on the 74. The SLR is Bulgarian copy of the 100 series which for some reason, possibly a patent issue but not sure, uses the akm bolt or a version of the akm bolt. Quote Link to post Share on other sites

Member on another forum rebarreled his 74 to 47 caliber, and this was all he changed. The places that sell the recoil springs don't say springs that only fit only a 47 or 74. The complete recoil assembly are marked for either, but not the springs. The springs interchange. I tried an akm recoil assembly on a saiga and it fit on there fine.
