I really like my PTR-91. It is very accurate out of the box and soft shooting for a .308. However the only feature I dislike is the magazine release. It is a push-button like an AR-15 but I vastly prefer the HK-91 style latch mag release. I am used to the latch style on the Mini-14, which works very well, and changing mags with this push-button on the PTR is aggrevating. Is there any way to install a latch mag release on the PTR-91? Has anyone done this?
