I want to build an underfolder, what are my options?

lonerunner1 · 04-12-2005, 10:10 PM

I have seen a few Russian AKM underfolder parts kits around, and some Polish PMKMS underfolders. Don't know where I should buy them. Yugo M70 underfolders are making their way in to, but I hear they have an RPK trunion and need an RPK receiver.

1. What kit should I go with, a traditional kit like the Russian or Polish, or wait for an M70? Where is a good place to buy them?

2. Does anyone make RPK receivers? I hear the FAC is supposed to make one in the near future.

3. With a standard AK receiver, does the underfolder rear trunion cover the rear of the receiver or does a plate need to be added to cover the whole at the end of the receiver?

Personally I would go with the Yugo underfolders that Centerfire has in stock right now for like $150. You can get an 80% receiver from www.coldsteelsolutionsincorporated.com or FAC is gauging interest for 100% receivers in the near future. Personally I don't know why FAC is waiting on this one, there are 1000's of these Yugo kits in the country right now and 100s of guys just itching to build them.

The trunnion fills the rear, if you can find a Polish get it they are very nice, most of the Russions are worn out that I have seen, it loogs like the Yugos are worn out too, I was dissapointed in the ones I just recieved.
