Chinese NHM-91, caliber 7.62 x 39 with UltiMAK M2-B optic mount. The sight is a Tasco Propoint 2. Several have asked us if the UltiMAK AK optic mount will fit this rifle. The photo was taken by a customer, who had this to say; “Folks at UltiMAK – I’m just writing to let you know that I couldn’t be happier with my scope mount – The quality of your product was beyond what I expected – Your instructions were detailed and installation was a breeze – The scope mount was just the thing I needed to finish off my NHM-91 – Thank you very much.”
