79式的外贸型主要有两种，一种是保利（Polytech）出口的，称为PDM-86，另一种是北方工业（Norinco）出口的，称为NDM-86。国外对这两种枪的评价是：是一种优秀的狙击步枪，但比不上原苏联的设计。NDM-86也有两种型号，一种是EM351，发射俄制的7.62×54mm R弹，另一种EM352，发射西方的7.62×51mm北约标准弹。题图为EM352的NDM-86，弹匣形状为直弹匣，这是区分EM351与EM352的主要特征。

据说EM352曾发生过未闭锁击发的事故，把机匣炸损。其原因是这种枪的击针是自由浮动式的，在推弹上膛时有向前的惯性力，军用弹的底火较厚，不会提前击发，但市场上的各类商业.308弹性能不一，遇上一个底火较薄的就出事故了。后来采用的被救方法是在击针外加装一个弹簧。
另外前面提到的枪/镜结合问题也同样出现在NDM-86上，丁丁早些年曾购买过一把EM352，第一次上靶场较枪，结果较了半天都较不准，因为每一枪都震得让瞄准镜移了位。

在试验中，EM352在100码上散布为0.75英寸，可见其精度也是不错的

NDM-86也可以使用俄罗斯生产的SVD专用两脚架
