My PTR-91 (A3R) set up as a DMR/SDM type rifle. It’s chambered in standard 7.62 NATO wearing a Vortex Viper PST (1-4x) optic.

I like the retractable A3 stock assembly aka ‘meat tenderizer’. They draw a lot of criticism but I haven’t found it to be significantly detrimental to achievable accuracy and handling, considering how compact I can make the rifle for transport and storage, so I’m keeping it.

The optic is great. I feel like Vortex optics are very reasonably priced for the quality of product available through them. Clear, bright, sharp, precise and rugged.

This setup will do 2-3" MOA groups all day long with milspec ball and I can bring it down to around 2" MOA with something a little nicer. More than adequate in it’s role.
