I don't think its been brought up here but I have had MANY requests to make magazines for the Yugo M77.
I have in the past felt that it was out of our reach to make magazines of this type due to our past designs requiring weld on feedlips. Thanks in part to the Saiga 12 magazine project, and all the totally annoying parts we have had to make for it. We are at the point that we can probably tackle this.
Our current goal is to make the M77 magazine in a one piece body, much like the original magazines are made. We are using a few magazines to base parts off of, I don't like the factory 20rd M77 magazines for a few reasons.. They have a hurried feel to them, like the maker got mostly done with a good design and threw in the towel.. Interestingly the magazine is almost exactly the size of a Galil .308 mag, however due to the design of the Galil front catch it won't fit in the M77. So we are thinking its possible to get both rifles with the same magazine design with only a small alteration.
Some may ask why the M77 and not a PSL or .223. The main reason for this choice is that we have data on the .308 and want to try making a more economical magazine, which will allow for us to take the data and transfer it to the next design.
We hope this is going to be a good step up in quality, while reducing costs a fair amount.
We are still working on the Saiga-12... And I am still making updates to other projects, we hope that 2014 will have four or five new product releases.
