Easy to install and solid

Written by Josh Rouse on Aug 28th 2023

Unbolt the old stock and bolt in the new mount, easy as that. Everything fits snug with no play or rattle. Cut and finish is immaculate like all JMAC products.

Everything fit perfect! I had a triangle folding stock on my Zpap M-70 and was a breeze to assemble

Excellent product

Excellent mount, very snug to the receiver, no wobble. Well worth the money, let’s go Brandon

Fitment and machining

Written by Matthew Barth on Nov 4th 2021

Great piece, fits very tight had to tap it in with my punch hammer. Well machined and coated. It's the way to go for updating your yugo. Mine was a newer zastava m70.

Great product for the Zastava M70 ZPAP, bit of a snug fit but got it in with a rubber mallet.

1913 Mount

Mounted to a newer Zpap m70, required some minor filing to get to fit but once done it was worth it, sits flush and looks factory.

Using the RSA-YFS with the SS-8R

Written by Kobe Green on Jul 22nd 2021

So I got this adapter along with the SS-8R with the sig mechanism and it is leaps better than just a plain fixed stock The adapter only needed a tiny bit of persuasion and she slid right into place, a little lock tight on the bolt and I feel like it's never gonna leave, the Sig Mechanism grips it tight with no wobble so the whole system is very sturdy, I would definitely reccomend both if you want to turn your fixed stock yugo into a folder.

The fitment is perfect, just enough interference to create a rock solid mount. Highly recommend this adapter!

QC is beyond reproach. I have used several different adapters for YUGOs and this unit is the best made I have come across. The fit is as perfect as you can get, bar none. The finish is amazing. The best though is doing business with JMAC. While most vendors are telling customers it can be 5-10 days before orders are filled, NOT JMAC. I ordered on a Friday evening and received acknowledgement of the order that same evening. The next day, which was Saturday I received notice that item had shipped. I received my order in timely manner. I had a few questions and was pleasantly surprised when my questions were answered in less than an hour. Mss Ashley has definitely brought her A Game. I am so pleased to do business with JMAC that they will be first call on products they can supply.

Good quality, fit was immaculate. Very easy to install. If you have any questions or concerns about install JMAC has tutorial vids on Youtube for just the occasion and they are quick to answer questions on their website as well. Over all, very impressed. Will be a continued customer as long as they pump out the same quality products they have been. Folding stock up next!

Quick shipping and great price. Just what I needed to finish my Npap side folder conversation. The adapter fits like a glove. Nice, clean look. Will definitely continue to shop jmac in the future.
