Yugo underfolder question

[lower lover]

My yugo underfolder parts kit came today had a few questions. Looked around and could not find the answers that I wanted. If any one can add any thing to help I would appreciate it.

1.I believe that my kit is a yugo fixed stock front half and the back is from an underfolder kit. My front half has the sites for the grenade launcher and I thought that it was only placed on the fixed stock kits, I could be wrong though.

2.is the front half of a yugo fixed stock different from that of an underfolder?

3.Also should the back half have and corresponding serial numbers to match the front half?.

4. If they are different will they still work together.

thanks

The GL front sight is on both versions.

1. All M70's (fixed and folder) have grenade sights.

2. Nope, they're the same.

3. I've looked my folder over and my rear trunion is not marked. Only numbered parts are the front trunion, bolt, carrier, and top cover. recoil spring, and gas tube.

4. The beauty of the AK is that the tolerances are such that parts from AK's from different countries will work together. Yes, they will work. Just make sure to check the headspace regardless whether it's a numbers matching kit or not.
